Manual click here to opennote this product is a step down module and cannot be boosted the input voltage is 55v and the output voltage can be adjusted from 0 50v if the output voltage is 12v the minimum input voltage should be 14v the input voltage should not exceed 55v it must be dc and not ac highlights 1 the lcd can display input output voltage output current output power output capacity output time 2 numerical control adjustment precise and fast step down output arbitrary adjustment of output voltage 0 50 00v arbitrary adjustment of limited current 0 20 00a 3 the output terminal will not burn when it is poured backwards 4 the module can be set to be turned on off by default 5 has a variety of software protection mechanisms and the protection threshold is adjustable when the working parameters of the module exceed the protection threshold the output will be automatically turned off 6 using synchronous rectification technology high conversion efficiency more than 90 efficiency 7 increase the heat sink and install a fan to enhance heat dissipation feature model wz5020ldisplay lcdinput voltage range 6 55 00vinput voltage resolution 0 01voutput voltage range 0 50 00voutput voltage resolution 0 01voutput current range 0 20 00aoutput current resolution 0 01aoutput power range 0 1000winput voltage accuracy â 1 5 output voltage accuracy â 0 3 5 output current accuracy â 0 5 5 typical value of output ripple 150mv peak valuenormal operating t
