2pcs DC-DC Adjustable Step Down Power Supply Module LCD Display w/ Shell


Free Shipping

DC-DC Step Down Power Supply Adjustable Module with LCD Display / Housing Case, made of high quality material, is of great durability. This module is regularly used for many digital goods. This is a sort of depressurization module, so the input voltage must be higher than the output. At the same time, it has no reverse polarity protection. You should pay much attention to the correct connection. With indicator lights, you can easily notice whether it′s charged or not. It also features high efficiency and less heat productivity. You deserve to own such a good gadget!

Extra Info

Calibration method:

Power-off status, press and hold the left button access the power, the display starts flashing, release the left button. using multimeter measured the output terminal voltage, if the measured voltage is greater than 5V, press the left button reduced the voltage to 5V; if the voltage is less than 5V, press the right button to increase the voltage to 5V. When the LCD display voltage of 5V(sometimes it shows 4.99V), turn off the power, the calibration is complete.
