DC-DC 12-70V High-power Wide-voltage Automatic Buck-boost Constant-current and Voltage-stabilized Vehicle Charging LED Power Module-with heat sink and fan

Features: Use high thermal conductivity aluminum substrate to adjust the meter, convenient for external radiatorInput ultra-wide range, can boost, buck, and stabilizeAchieve zero voltage difference between input and output, adjustable
output voltageModule parameters: Module
nature: non-isolated
voltage regulatorInput voltage: 10.5 -70V DC (please use derating when the power supply voltage is lower than 12V)
Input current: 10A max, long
time 8A maxOutput voltage: 5-58VDC
Output current: 8A max, 6A max for a long time (Do not allow the input and output current to work at the maximum value, the sum of the input and output current cannot exceed 12A)Constant current adjustable: 0.5
-8AOutput power: 180W max (maximum current 8A when working at low voltage, maximum output 30W without auxiliary heat dissipation on bare board, with heat sink without fan, maximum output 50W, when the module temperature exceeds 65 degrees, heat
dissipation is required)Standby current: about

Output voltage/current adjustment method: 1. Adjust the constant voltage adjustable potentiometer (decrease the voltage clockwise, increase the voltage counterclockwise), according to your load requirements, set the output voltage to the voltage value you need. For example, the voltage of 10 LED strings is adjusted to 37V. 2. Adjust the constant current adjustable potentiometer clockwise about 20 turns, set the output current to the minimum, connect the LED, and adjust the constant current adjustable potentiometer to the current you need. For battery charging, after the battery is discharged, connect to the output and adjust to the current you need. (When used for charging, you must use the discharged battery to adjust, because the battery has more power, The smaller the charging current. ) Please do not adjust the current in a short-circuit mode. The circuit structure of this buck-boost module cannot be adjusted in a short-circuit mode.
