DC-DC Buck Voltage Converter 4.5-40V In to 5V/2A USB Out Step-down Voltage Regulator Module Power Supply Charger Board with LED Voltmeter This unique dual function DC-DC Buck step-down voltage converter accepts 4.5V to 40V input and provides an LED voltmeter to monitor the input voltage. With input voltages from 6.5V to 40V, it will generate a regulated 5V USB output at up to 2A that can be used to power or charge a cell phone, MP3 player, or any device that is powered by 5V USB power. Features: Input voltage/ voltmeter range: DC 4.5~40V, (with input voltage from 6.5V to 40V, can generate a 5.0V regulated output) Output voltage/current: 5V/2A Voltmeter display can be calibrated Reverse polarity, over current and over temperature protection Output enable button turns On/Off the USB output power. USB power indicator LED illuminates when output is enabled Lower Power button disables output and display and puts module in a low power mode High-efficiency, low ripple Dimensions: 58mm * 21mm * 10mm (L*W*H) Net weight: 13g Instructions for use: At power-on, the voltmeter digital display will display the input voltage level. To charge or power a phone, Tablet PC, or MP3 player, press the "Output Enable" button. The USB power indicator will illuminate, and 5.0V will be applied to the USB output connector and the output solder pads. To turn off the digital display, press the "Low Power" button. The module will enter the low-power standby mode, the display will be disabled and the USB output shut down. Voltmeter calibration: With power applied to the module, and voltage is displayed on the LED meter, press and hold the "Output Enable" button for 2 seconds then release, the voltmeter will flash. Touch the "Output Enable" button, the voltage increases one unit, touching the "Low Power" button will reduce the voltage by one voltage reduction unit (one unit is less than 0.1V). After the voltage calibration is completed, press the "Output Enable" button for 2 seconds then release to exit voltage calibration mode. When powered off, parameter settings will automatically be saved. Applications: Car / motorcycle battery voltage monitoring, or other voltage measurements. USB Charger for mobile phone, MP3 player, Tablet PC or other electronic products. Please Note: this module defaults to the USB connector pins D+, D- are shorted, which is compatible with most cell phones. If the phone requires an identification resistor, such as the IPhone, please cut the trace at the red line position in the image below.
