Specification: Item Type:Power Supply Module Model:WD5020 Input Voltage:7~50V Output Voltage:0~36V Continuous AdjustableCan only be used as a step down module, the input must be greater than the output 1V or more Output Current:Adjustable,20A MaximumIt 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 degrees Celsius 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 types: 1. F-0 mode: display output voltage; 2. F-1 mode: display input voltage; 3. F-2 mode: alternately display input and output voltages; Instructions for use: Press the “+” button to cycle through the three display modes. Press the “-” button to save and exit. Press the “-” button alone toswitch the backlight of the LCD screen.Application range three applications Note that the constant current adjustable current must be in the constant current mode when the actual load output current is greater than the set current. Otherwise, it will work in the constant voltage state. It is not the current adjusted to 2A, that is, any equipment will change to 2A. Know. Constant current above 2V output voltage will take effect! 1. Use as a normal step-down module with overcurrent protection Instructions: 1 Under no-load conditions, adjust the “constant piezoelectric device CV” to make the output voltage reach the desired voltage value; 2 Connect the load, connect the line with a thick point, adjust the "constant current potentiometer " counterclock is to reduce the size, the default factory is 10A, if the actual need is lower than the constant current 10A output, you need to adjust the counter clock The loop current display will change. The current value displayed by the ammeter is 4A, then the maximum current of the module is limited to 4A, and the red indicator light of the constant current indicator
