Feature

Come with protective shell, Large LCD screen, blue background and white digit, can be clearly seen in any angle, displaying voltage and current simultaneously.
A constant voltage and current module, Input voltage could be 6-32V; Output voltage could be 1.25~32V; input side must be 1.5 higher than output side; max output Power is 75W.
Made of imported MP2304 chip, high conversion efficiency of 96%, when current is higher than 3A or 35W, please enhance heat dissipation.
With voltage-calibration and current-calibration, designed with USB interface, it brings you many conveniences in most occasions.
Wide applicationsused as an ordinary step-down modules with over-current protection capabilities, as a battery charger, as a constant current LED driver module.

Description

Parameters Input voltage: 6~32V Output voltage: 1.25~32V (Input must be 1.5 higher than output.) Output current: Max.5V, adjustable, recommend the use of within 4.5A. (Over 2A or 35W, please enhance heat dissipation.) Constant current needs above 2V output voltage, then can be adjusted. Only in the status of constant current can current adjustment work. Output Power: Max. 75W (recommend the use of within 50W, please reduce power if the dropout voltage is large) Operating temperature: -20 ~+70 Operating frequency: 180KHz Conversion efficiency: up to 96% Short circuit protection: Yes Input reverse polarity protection: None Over-temperature protection: Yes (Automatically shut off the output when over-temperature.) Connection: terminals or solder terminals; VIN is input; VOUT is output Module dimension: 65.6 x 40 x 25mm Voltage-calibration Method: In the case of power off, press and hold the "SET" key and power on, then enter into voltage calibration mode, and LCD screen starts to flash, release the "SET" key; press "SET" and "ENT" key to increase or reduce the voltage to the right input voltage. It will automatically saves after 2s, then power off and the calibration is complete. Current-calibration Method: Suitable for no-load with current display or slightly large current. In the case of power off, press and hold "ENT" and power on, then enter into current calibration mode and LCD screen starts to flash, release the "ENT" key; press "SET" and "ENT" key to increase or reduce the voltage to the right value. It will automatically saves after 2s, then power off and the calibration is complete. Package Includes: 1 x DC-DC Adjustable Step-down Power Supply Module with Shell 4 x Copper Cylinder Screws M3*6 4 x Double-pass Screws M3*12 8 x Roundhead Screws M3*6
