Product Description
20A High-powe Adjustable Step-down Power Supply Module DC-DC 7V-50V To 0-36V Regulated Power Supply Voltage Current Dual Display
Features:
1. Using high-quality materials, durable
2. Exquisite appearance
3. Easy to use
4. High precision, stable and reliable
5. Wide range of applications
Specifications:
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 to use within 15A, 10A or below 180W can be cooled naturally at room temperature, please strengthen the heat dissipation when it exceeds! Constant current needs to be adjusted above 2V output voltage, current adjustment, only in constant current state 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 exceeds, please strengthen the heat dissipation)
Conversion efficiency: up to 95%
Short circuit protection: yes, the constant current value currently set by the constant current
Input reverse polarity protection: yes
Output reverse flow: no, please add a diode for charging and motor type
Wiring method: wiring terminal or welding terminal, VIN is input, VOUT is output
Module size: length 100mm width 60mm height 48mm
Special Note:
1. There are many customers who say that the MOS tube is burnt when they first use it. I would like to explain that it is used to charge batteries and connect motors and motors. 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!!
2. 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 is about 20V when it leaves 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:
Calibration method: This module has a calibration function, so you don't need to worry about the 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 perform a calibration!
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 to the correct input voltage, such as: the input voltage is 12.65V, then adjust the current voltage to 12.65V, automatically save after 2 seconds, and the calibration is completed after power off and exit!
