Module parameters:

DC-DC non-isolated high voltage step-down power module

Wide voltage input: 12V-120V (120V is the limit voltage, leave room for long-term work);

For the first use, it is recommended to connect a power supply of more than 30V;

Adjustable output voltage: adjustable between 1.25V-48V;

Input and output voltage difference: 5V (ie output voltage < input voltage -5V);

Output current: 1.5A (Max) The value of each input voltage point is different from that of the output voltage point, see the parameter table below for details;

Built-in over temperature, over current, output short circuit protection

Built-in soft start
