Module parameters Input voltage 6V 32VOutput voltage 1 5 32V continuously adjustable can only be usedstep down module the input must be greater than the output 1 5V or more Output current adjustable the maximum 5A recommended in the use of 4 5A when exceed 3A or 35W the best to strengthen the cooling Suggest using a small fan at the input terminal Constant current requires an output voltage of 2V or more to be adjusted the current regulation only in the constant current state will work constant current is mainly directly used to the low resistance battery charge or LED working current limit and other use please make sure about this before you order it Output power up to 75W recommended in the use of 50W if uses large pressure difference please reduce the power Operating temperature 20 to 70 degrees pay attention to the power tube temperature when exceed please strengthen the cooling Operating frequency 180KHzConversion efficiency up to 96 Short circuit protection Yes constant current Current set constant current valueOver temperature protection Yes over temperature automatically turn off the output Input reverse protection YesOutput reverse flow None for charging please add a diode Installation 8pcs pillars 8pcs 3mm screwsWiring method wiring terminal or soldering terminal VIN for the input VOUT for the outputModule size 65 6mm x 40mm x 25mm L W H Weight 77gCalibration method The module has a calibration function dont worry about me
