Operating voltage range: 6-36V. Maximum output current: 8A for low power version, 15A for high power version. Module self-consumption about 6mA or so Adopt ultra-low power consumption 8-bit MCU as the main control, switching quickly and accurately. Adopt high power and low loss MOS tube 2 power supply indicator lights on board, you can know the power supply status in real time. Switching time is about 0.1mS. On-board multi-turn potentiometer, can freely adjust the main power supply switching voltage and recovery voltage, convenient for a variety of different voltage occasions. The main power supply voltage can be higher or lower than the secondary power supply voltage. The module does not have charging function, the main power supply can not charge the vice power supply.
