DC 4.5-40V To 5V 2A USB Charger Step down Converter Voltmeter Module In Pakistan

The Buck Regulator module converts an input of 4.5-40V into a very stable 5V 2A output. The Step-Down Voltmeter device features a USB port through which you can charge your phone. While charging your device please consider that the output of this device is regulated at 5V 2A. Simply connect this device to the power supply, the voltage can be detected in real-time. When you need the phone, IPAD, MP3, and other digital products to charge, click the “Output Enable” button, then the USB power indicator lights up and Variable Power Supply will start supplying 5V 2A at its output. When you need to turn off the voltmeter, click the “Low Power” button, then enter the ultra-low-power standby mode, USB output corresponding shutdown.

Voltmeter Calibration Method:

1. Step1: Press the “Output Enable” button  more than 2 seconds, release, voltmeter flashes, this time into the voltage regulation mode;
2. Step2: Press the “Output Enable” button (normal speed), the voltage value is adding up a unit; Press the “Low Power” button, minus a unit; Due to a unit being less than 0.1V, the minimum voltage display to 0.1V, so you need to continuously press 1-5 times to see the voltmeter change 0.1V, how many times voltmeter change 0.1V by pressing the button, depending on the current display voltage, the higher the voltage, the fewer the number of press.
3. Step3: press the “Output Enable” button for more than 2 seconds, release, to exit the voltage calibration mode. Data is not lost after the power failure.
