Short-circuit protection: YES(limited current of 8A)
Over-temperature protection: YES(item will stop output atomatically)
Input reverse connection protection: NO (If necessary, connect the high-current diode on the input in series)
Installation: you need 4 screws with size 3mm
Wiring method: connect the terminals or welding terminals, V-IN: Input; V-OUT: Output
Module Features:
1. High-power, high efficiency, 5A, low ripple;
2. 3 IN 1:
(1) Work as buck module with over-current protection;
(2) Work as a high-power LED constant current driver module;
(3) Work as a charger for lithium batteries, batteries, nickel-cadmium nickel-metal hydride batteries (battery) with variety of voltage value; used for solar panels, wind turbines and other occasions;
How to set limited rate:
1. Yo can adjust constant voltage potentiometer in order to let the output voltage reach the voltage value you want;
2. Use 10A multimeter to measure short-circuit output current (directly connect two meters to output terminal), adjust constant current potentiometer at the same time to make output current reach preset over-current protection value. (If the current value on the multimeter shows 4A, the maxmum current of the module can only be up to 4A. When the current reaches 4A, constant-voltage constant-current red indicator lights on, or lighting off)
