DROK 091016 DCDC Buck Converter 438V Stepdown Voltage Regulator Module Adjustable Current 5A Max 75W High Power Volt Power Supply Transformer Board with Constant Current Voltage

Parameter Input voltage: 4-38V Output power: 75W(Max) Transfer efficiency: 96%(Max) Output current: adjustabel;5A(Max) Output voltage: 1.25-36V constantly adjustable Input reverse connection protection: NO Short-circuit protection: YES(limited current of 8A) Over-temperature protection: YES(item will stop output automatically) How to set current limits: 1. Adjust constant-voltage potentiometer to make output voltage reach the voltage value which you want. 2. Use 10A multimeter to measure short-circuit output current (directly connect two meters to output interface), at the same time, adjust constant-voltage potentiometer to make output current reach preset over-current protection value. (If the current value multimeter displays is 4A, the maximum current of the module only can be up to 4A; when the current reach 4A, constant-voltage constant-current red indicator light is on, or the light is off) LED indicator light: 1. Red light is on in constant current status and off in constant voltage status. 2. Blue light is on when charging and off when full-charging 3. Green light is on when full-charged. Package includes: 1 X Buck Converter
