DC4.5V-40V to 5V 2A USB Step Down Power Module

RWF 5,000.00

The DC4.5V-40V to 5V 2A USB Step Down Power Module is a versatile and efficient voltage regulator designed to step down a wide range of input voltages (from 4.5V to 40V) to a stable 5V output, capable of providing up to 2A of current. This makes it ideal for powering 5V USB devices such as microcontrollers, sensors, and small electronic projects, especially when the input power source is a higher voltage, such as a battery or solar panel. The module features a compact and robust design, making it suitable for use in both hobbyist and industrial applications. It is commonly used in various electronics, including Arduino projects, Raspberry Pi setups, and portable power banks, where efficient and stable voltage conversion is crucial. With its wide input voltage range, the module offers flexibility in different power environments, ensuring reliable performance and safe operation for your 5V devices.

Product Description

This is DC-DC 4.5-40V To 5V 2A USB Charger Step down Converter Voltmeter Module, 2A Charger and voltage checker.

The module converts input of 4.5-40V into a very stable 5V 2A output. The 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 USB power indicator lights up and it 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.

It accepts wide input voltage as from car/battery car/motorcycle used for monitoring battery voltage; measure the voltage needed for a variety of occasions. The output current capability 5.0V/2A, enough to meet a variety of USB devices.

Note:

This module default D + D- short, most of the cell phone charger is compatible, and set aside a variety of mobile phones identification resistor installation location, if you need to add the identification resistor, please connect D + D- wires cut, then added.

Voltmeter Calibration Method

Step1: Press the �Output Enable� button more than 2 seconds, release, voltmeter flashes, this time into the voltage regulation mode.

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 is 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.

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.
