20A DC DC Converter Voltage Meter Adjustable CC CV Step Down 7V-50V to 0-36V Regulated Power Supply Battery Charging Board

Features:

1. Using high quality materials, durable

2. Refined appearance

3. Easy to use

4. High precision, stable and reliable

5. Wide range of applications

parameter:

Input voltage: 7V-50V

Output voltage: 0V-36V continuously adjustable (can only be used as a step-down module, the input must be greater than the output 2V or more)

Output current: adjustable, maximum 20A (recommended for use within 15A, 10A or below 180W can be naturally cooled at room temperature, please strengthen the heat dissipation when it increases! Constant current should be adjusted above 2V output voltage, current adjustment, only in constant current mode will work below.)

Output power: Maximum 300W (recommended to use within 250W, please reduce the power when using large pressure difference)

Working temperature: -20~+75 degrees (pay attention to the temperature of the power tube when using, if it rises, please strengthen the heat dissipation)

Conversion efficiency: up to 95%

Short circuit protection: Yes, the constant current value is now set by a constant current

Input reverse polarity protection: Yes

Reverse flow output: None, please add a diode for motor type charging

Wiring method: terminal wiring or terminal welding, VIN is input, VOUT is output

Module size: length 100mm width 60mm height 48mm

Important thing: Many customers said that they burned MOS tubes when they first started using them. I want to explain in particular that they are used to charge batteries and connect motors and engines. Remember to add diodes to the output of the module to prevent backflow. If no reflux is added, the tube will be burned, remember, remember!!

Special Note: Some customers reported that the output voltage could not be adjusted when they first received the product, because the default output voltage of the module was around 20V when it left the factory. When you encounter this kind of problem, please turn the CV potentiometer counterclockwise for more than 10 turns until the voltage value changes, and then use the module to adjust the voltage normally.

Calibration method: This module has a calibration function, so you don’t need to worry about inaccurate measurement display, you only need to calibrate it once! The factory has been calibrated by default. If the display of the received product is inaccurate, you can use the following method to calibrate!

Voltage calibration: No load, in case of power failure, press and hold the “+” key, power on, enter the voltage calibration mode, the LCD screen starts to flash, release the “+” key, press the “+” key to add, “-” ”is minus, calibrate the correct input voltage, such as: the input voltage is 12.65V, then adjust the input voltage to 12.65V, it will automatically save after 2 seconds, and the calibration will be completed after power off and exit!
