Electrical power

Trust UPS teardown

An uninterruptible power supply (UPS) is an electrical apparatus that provides emergency power to a load when the input power source or mains power fails. The on-battery runtime of most uninterruptible power sources is relatively short (only a few minutes) but sufficient to start a standby power source or properly shut down the protected equipment.

Measuring AC power with the Industruino PROTO

https://blog.arduino.cc/2016/11/21/measuring-ac-power-with-the-industruino-proto/ This project uses DIN rail mountable Arduino to measure electrical power consumption. This robust DIN rail mountable, Leonardo-compatible controller enables you to take your existing Arduino projects and swiftly transform them into permanent installations. The prototyping area and screw connectors allow you to install your own circuitry and reliably connect to accessories.   Interview With
