Input voltage :DC12V-60V, do not use less than 12V input voltage, full load output greater than 60V, when the input and output voltage difference is large, should be appropriate to reduce the output power. The greater the voltage difference, the lower the efficiency of the power supply and the greater the heat output. Maximum input current shall not exceed 100A, power shall not exceed 2000W output voltage :DC15V-80V, maximum output current shall not exceed 50A, power shall not exceed 1850W Undervoltage adjustable range :DC10.5V-50V(decrease clockwise, increase counterclockwise), first adjust the undervoltage to the minimum, then adjust the input voltage to the required undervoltage protection value, and then slowly increase the adjustable value counterclockwise, when the undervoltage indicator lights up, turn it back one or two turns, and then reconnect the power supply The power supply is equipped with intelligent temperature-controlled fans. When the temperature of the power supply reaches 55-60 degrees Celsius, the fan will automatically turn on. When the temperature of the power supply drops to 50 degrees Celsius, the fan will automatically turn off. When the output of the module requires constant current limiting, the input and output ground cables must be connected separately and cannot share the same cable. When using switching power supplies or other secondary power supplies, ensure that the power supply should be greater than twice the power of the module. The output blue indicator lights up only when the power supply is increasing. When the power supply has overcurrent or undervoltage protection, the output still has a voltage close to the input value, and the protection is only that the power supply does not boost the voltage. Package Included: 1*12V-60V to 15V-80V 100A 2000W DC Boost Power Supply Output Charging Module
