What is Class 4 Fault Managed Power?
https://www.necanet.org/neca-bicsi/schedule/session-detail/what-is-class-4-fault-managed-power

Class 4 is a new circuit term defined in the 2023 edition of the NFPA 70, commonly referred to as the National Electrical Code (NEC). Class 4 is defined in a new Article 726 that is part of chapter 7 which deals with special conditions. Class 4 systems are referred to as “Fault Managed Power Systems” (FMPS). These systems are not power limited and can deliver hundreds or thousands of watts of power. The voltage can be up to 450V AC or DC which sounds dangerous. However, these systems intelligently limit the amount of energy that can go into a fault. Limiting the fault energy mitigates the risk of shock or fire and allows the installation of Class 4 circuits using methods like power-limited circuits. Attendees will learn how Class 2 and Class 4 circuits can be used to deliver more than 100W at distances above 100m. How a DC based power infrastructure can save on CapEx (material and labor costs), control their energy use to reduce OpEx, and use less materials for less embodied carbon per project. VoltServer is the pioneer of fault managed power systems and has thousands of installations using this technology under existing electrical codes supporting applications in wireless communications, intelligent buildings, and controlled environment agriculture (CEA).

Monitoring for Predefined Faults

Fault managed power systems should all monitor for these fault conditions, and stop power within a few milliseconds if any of these faults occur:

An abnormal condition such as abnormal voltage, current, waveform, or load condition is identified in the system
Short circuit occurs
Human skin contact with energized parts
Ground-fault condition exists
Overcurrent condition exists
Malfunction of the monitoring or control system
Intentional shorting of the line at the receiving or transmitting end to force de-energization for purposes of maintenance or repair occurs

There are several benefits to power systems that can monitor for predefined faults. Fault management is primarily a safety feature that, among other benefits, permits higher voltages to be transmitted along cables (up to 450V in the current Class 4 standard). They are able to distribute higher voltages because the rapid shutdown of power (when a fault is detected) significantly reduces the risk of electrical shock and fire. The use of higher voltages comes with its own benefits. For example, cable gauges can be smaller when carrying higher voltages, resulting in lower project capital costs associated with cabling. Furthermore, fault management enables Class 4 systems to be installed by the same technicians who install PoE cabling (depending on local regulations), which can potentially eliminate the need for electricians during installation.

Higher Voltages Carried Along Cables

Fault managed power systems should all be able to deliver hundreds (or even thousands) of watts of power, at up to 450V. When compared to a Class 2 power system, which can only deliver up to 100VA (or 100W at up to 60V), Class 4 power systems (synonymous with fault managed power systems) can practically deliver up to 20 times more power. Class 4 systems don’t technically have a power limit, because there is no current limit, only a voltage limit of 450V.

Prepare for Hybrid Fiber Cables

A hybrid cable incorporates optical fibers (for data transmission) and copper wires (for power transmission) within the same jacket. The power transmission wires would ideally be part of a Class 4 power system so cables could be fault managed, and carry higher voltages, while being about 10 times thinner than cables carrying 48V power.

The main benefit of hybrid cables is that they enable long-distance power supply while ensuring high-speed data transmission. Additionally, similarly to Power over Ethernet (PoE), they reduce cabling required because, instead of needing separate cables for both power and data, one cable can be used for both. This could reduce project costs associated with cabling, as well as simplify cable management. Hybrid cables are a distribution medium for both Class 4 power and data for 5G, so they are extremely beneficial when used in telecom infrastructure.

How A Fault Managed Power (FMP) System Works

As we mentioned, the technology involved in Class 4 power systems varies depending on the manufacturer. Because of this, in order to demonstrate how a Class 4, fault managed power system works, we’ll use Cence Power’s system as an example.

‍

Step 1: In a Class 4, fault managed power system, a Class 4 transmitter is connected to the main power supply of a building (such as an electrical panel). It includes an AC to DC converter, and DC-DC converter.

The intelligent transmitter converts AC to DC power, and steps up DC voltage levels with a DC – DC converter to up to 450V DC.

‍

Step 2: Up to 450V DC flows through fault managed cables, with the transmitter and receiver continuously monitoring for faults on either end of cables.

Even though they can send higher voltages, fault managed power systems can often make use of low-voltage wiring practices. This is because an intelligent power transmitter and receiver are constantly monitoring cables for faults, and will shut power off if one is detected. Using low-voltage wiring practices can save on project capital costs associated with cable. Additionally, because fault managed power systems can supply power at higher voltages (up to 450V DC), cables suffer less line losses than a low-voltage system.

‍

Step 3: Power arrives at a Class 4 receiver

Before power reaches a load, it goes through a receiver that lowers the voltage levels for the last stretch of cable, commonly referred to as the “last-mile.”

‍

Step 4: The DC power load (such as an LED light fixture or telecom cell) receives power.

The Future of Fault Managed Power Systems

Although they are only in their naissance, companies such as Cence Power have already begun to offer fault managed power systems. Fault managed power systems will pose strong competition for traditional AC power systems because they can provide just as much power, and do so more safely and efficiently. Thus, although it would take time, fault managed, Class 4 power systems could someday be the primary electrical system in buildings.

A recent report from Guidehouse Insights states that the global market for Power over Ethernet (PoE) is anticipated to grow from $113.8 million in 2021 to $614.9 million by the end of 2030. The growth of PoE is being driven in part by the rise in smart building development and will be further fueled by a variety of emerging digital power technologies

According to Young Hoon Kim, senior research analyst with Guidehouse Insights, “PoE is expected to be a key connectivity solution in building network infrastructure. Many building network renovations and new building construction projects are expected to adopt the technology due to its core benefits of reliability, flexibility, and easy installation.”

While PoE has long been touted for its easy installation and reduced labor costs, eliminating the need to run traditional AC electrical wiring to power connected smart building devices, industry experts say cost is no longer the driving factor.

Are DC microgrids the way of the future?

As discussed in the white paper “DC Lighting and Building Microgrids” from the U.S. Department of Energy’s (DOE) Pacific Northwest National Laboratory, DC building microgrids that draw from on-site solar and energy storage can allow entire buildings to disconnect from the traditional power grid during outages.

Emerging digital power technologies

When it comes to delivering digital power throughout a smart building, Suau points to three main technologies of focus—PoE, USB-C, and digital electricity. PoE has already experienced significant advancements since it was introduced almost two decades ago, advancing from delivering 13 watts to IT networked devices to now delivering upwards of 75 watts. Single-pair Ethernet technology under development to support low-speed data connections over longer distances to OT networked devices, such as building automation sensors and controllers, will also deliver a form of PoE, or SPoE. Depending on the cable length, SPoE is targeted to support between 7 and 52 watts.

USB-C power delivery is a relatively recent technology introduced by the creators of the USB standard

With its ability to charge smartphones up to 70% faster than previous-generation USB technology, USB-C is rapidly gaining ground. While the first iteration of USB-C topped out at 100 watts, the USB Implementers Forum (USB-IF) recently announced that it’s working to more than double the amount of power to 240 watts, enough to power a high-end laptop.

“It’s becoming universal, and most laptops and smartphones are embracing it,” says Suau. “It extends DC power throughout a building by working in conjunction with PoE—we’ll now have devices that are powered by PoE in turn powering other devices by USB-C.”

Class 2 power, which includes but is not limited to PoE, delivers low-voltage DC power for applications including LED lights to thermostats. For powering connected devices in a smart building that are beyond the distance limitation of PoE or don’t have a copper network interface, Class 2 power can be delivered via copper conductors in hybrid fiber cable.

A new type of power getting attention is fault managed power, which is expected to be included in the next National Electric Code as Class 4. Fault managed power transforms AC or DC power into a pulse current waveform that is delivered over common multi-conductor power cables like those use in hybrid fiber cables. Each pulse has a short duration of time, and if the power is touched or shorted, it is automatically detected by a fault prevention system and stops transmission within milliseconds—far faster than a traditional AC circuit breaker for improved safety.

Fault managed power is expected to provide about 20 times the power over 20 times the distance of PoE, and it costs less than traditional AC due to smaller copper wires and the potential for installation by low-voltage contractors versus licensed electricians. “While Class 4 does communicate fault information, we don’t know yet if it will be expanded in the future to deliver more data. It an early technology,” says Suau.

The digitalization of buildings, agriculture and outdoor stadiums require deploying intelligent edge-sensors to facilitate real-time data transmission to the cloud. Powering these intelligent sensors, which often includes communications and processing capabilities, is challenging due to the long-distance cable runs needed which can be inefficient and expensive to deploy. Running heavy gauge wiring through large stadiums, convention centers, office towers, warehouses, and vertical farms is a labor-intensive hurdle to overcome to deliver digital intelligence to these venues. Digital Electricity™, a patented new technology of VoltServer, simplifies and optimizes the installation and power delivery for smart applications. VoltServer’s approach reduces costs and capitalizes on efficient power delivery over long distances, providing numerous advantages compared to conventional electrical installations. With Digital Electricity™, up to 2kW of power can be efficiently and safely transmitted across long distances up to 2km using low-cost, off-the-shelf data cables.

VoltServer takes conventional electricity and breaks it into small pulses, or “energy packets.” Each packet is sent to a receiver from a transmitter that contains local, embedded processing capability. Each energy packet is analyzed using a digital signal processing engine to determine that power is being precisely and safely distributed; and if a fault is detected the next energy packet is not sent. Each packet contains only a very small amount of energy, so individually they are not harmful to people, animals, systems, or buildings.

Vicor ruggedized, passively-cooled DC-DC fixed-ratio bus converters are located in the receivers. They provide the power efficiency that allows the receivers to be placed in tight, enclosed spaces that are too small to permit the use of active cooling.

Vicor BCM6123 fixed-ratio bus converters uses a proprietary, low-noise, high-efficiency Sine Amplitude Converter (SAC) topology that requires little electromagnetic filtration. This further reduces cooling requirements, which lowers total cost of ownership by reducing power losses.

“With the Vicor converter, we have 43% less heat loss than a normal converter, and the heat sink size decreases disproportionately,” said Dan Lowe, VoltServer’s co-founder and Chief Business Officer. “Also, the Digital Electricity™ receiver may need to be outdoors, and ideally it operates without a fan to cool it. That’s where Vicor comes in really, really neatly.”

Digital Electricity™ offers the benefits of low-voltage with the power and distance capabilities of AC high voltage. It’s easier to install long runs using light-weight cabling and it conforms to the NEC and CEC Code.

PoE on Steroids: “Digital Electricity” Hub Uses Standard Ethernet Cable to Deliver Up to 2 kW Over Long Distances

VoltServer Inc., based in East Greenwich, R.I., has introduced its Digital Electricity technology that can safely transmit Ethernet data and up to 2 kW of power across long distances (up to 2 km) using low-cost, off-the-shelf data cables. Created to serve the growing number of applications with large numbers of remote nodes that require power and data, VoltServer’s systems have been deployed in hundreds of marquee venues including stadiums, airports, convention centers, office towers, hotels, condominiums, hospitals, and indoor gardens. They power 4G, 5G, and Wi-Fi wireless communications, LED lighting, and IoT applications.

Pulsed Power Transmission

VoltServer’s Digital Electricity systems are able to deliver much more power than conventional Power over Ethernet (PoE) technology because they get around the low-current capacities of lightweight data cable by using high-voltage, low-current pulses to deliver power to downstream loads. VoltServer refers to these pulses as “energy packets.” These are distributed from a transmitter containing local, embedded processing that can determine if the power is being precisely and safely distributed. If a fault is detected, the next energy packet is not sent.

Each packet contains only a very small amount of energy that’s not individually harmful to people, animals, systems, or buildings. Each end point is equipped with a receiver that converts the high-voltage pulses back into analog ac or dc to power local loads.

Plug-and-Play Power Sources

Similar to PoE, VoltServer’s Digital Electricity delivery system can simultaneously send data and power over a distance up to 2,000 meters using off-the-shelf structured copper communications cable and Class 2, low-voltage wiring methods. Since this is easier and more economical to install than conventional 110/220 electrical systems, architects, designers, and facility managers can quickly and easily configure and reconfigure wireless networks, office floorplans, and agricultural grow rooms.

In addition, because the platform is natively digital, it allows users to monitor energy use with a centralized dashboard. This gives building operators and maintenance staff a granular view of their electric grid to better manage critical loads while eliminating the need for traditional circuit breaker panels.

In the end, VoltServer chose the Vicor BCM6123 for use in the endpoint receiver. Not only is the converter 97% efficient, it has a very compact footprint (0.99 × 2.402 × 0.286 in.).

The lower cooling requirements afforded by the BCM6123 allows the receivers to be placed in tight, enclosed spaces that are too small to accommodate cooling fans.
