Specification:

Item Type:Power Supply Module

Model:WD5020

Input Voltage:7~50V

Output Voltage:0~36V Continuous Adjustable(Can only be used as a step down module, the input must be greater than the output 1V or more)

Output Current:Adjustable,20A Maximum(It is recommended to use it in 15A. It can naturally dissipate heat at 10A or below 140W. If it exceeds, please strengthen the heat dissipation! Constant current requires output voltage of 2V or more to adjust. Current regulation can only work under constant current state.)

Output Power: Up to 300W (recommended to use within 250W, please reduce power when using large differential pressure)

Working Temperature: -20~+75 ℃ (pay attention to the power tube temperature when using, please strengthen the heat dissipation)

Working Frequency: 300KHz

Conversion efficiency: up to 95%

Short Circuit Protection: Yes, constant current value currently set by constant current

Input Reverse Connection Protection: Yes

Output Backflow: No, please add a diode for charging!

Wiring Method: Terminal block or soldering terminal, VIN is input, VOUT is output

Size:100 x 60 x 48mm / 3.94 x 2.36 x 1.89in

Calibration method: This module has a calibration function, so you don't have to worry about the measurement display being inaccurate. Just calibrate once! The module has been calibrated when left factory, if the module displayed inaccurately, you can use the following method to perform a calibration!

Voltage calibration: Under no-load condition, press and hold the ''+'' button, power on, enter the voltage calibration mode, the LCD screen starts to flash, release the ''+'' button, press the ''+'' button to add, ''- ''to reduce, calibrate to the correct input voltage, such as: input voltage is 12.65V, then adjust the current voltage to 12.65V, automatically save after 2 seconds, the power is off and the calibration is completed!

Setting instructions:

The "+" button sets the display mode and is divided into three
