Module name: 400w
Module nature: Non isolated buck module (BUCK)
Input voltage: 10.5-60V
Output voltage range: 0-45V (must meet voltage reduction conditions, IN input multiplied by 0.8)
Minimum output voltage: 0V (+1V)
Maximum output voltage: approximately equal to input * 0.8 (for example, if the input is 40V and 40V * 0.8=32V, the maximum output voltage is 32V, which will actually be slightly higher and reach around 34V.35)
Output constant current: 0.2-15A (continuously adjustable, over 12A, heat dissipation should be strengthened)
Maximum output power: 400W (requires adding a fan for forced cooling of the heat sink and magnetic ring)
Continuous maximum working power: 280W (in a ventilated environment)
Continuous maximum working current: 12A (in a ventilated environment)
Input undervoltage protection: Yes, (when the input is below 10.5V, the output is closed, with an error of about 0.5V)
Input overvoltage protection: None (overpressure prohibited)

Main features of the power module:
10-60V wide input voltage, suitable for most power sources on the market as input sources.
Output constant voltage and current, continuously adjustable voltage and current. Can meet the needs of most electrical equipment.
The output power is large, with good ventilation and natural heat dissipation, which can achieve 280W/12A (note that there are output power and output current limitations).
