DC-DC 스텝 다운 모듈 -전압측정 지원, 5V/2A USB 출력
(DC-DC Step-Down Module with Voltimeter - 5V/2A USB Output)
개요
- 본 제품은 DC 6V - 40V를 입력 받아 5V/2A를 USB로 출력하여 줄 수 있는 스텝다운 모듈입니다.
- 모듈상에 디스플레이를 통해 전압을 측정할 수 있습니다.
- 모듈상에는 두개의 버튼이 있으며, low power 버튼을 누르면 voltimeter 디스플레이를 off시킬 수 있습니다.
- 출력은 USB output enable 버튼을 누르면 5V가 USB로 출력되게 됩니다.
- 모듈 뒷면에 장착되어 있는 저항을 교체 조절하여 용도에 맞게 제품 튜닝이 가능합니다.
특징
- Parameters:
Input voltage/ voltmeter range: DC 4.5~40V (please input voltage 6.5 ~ 40V , then can get a 5.0V stabilize output)
Output voltage/current: 5V/2A
Module dimensions: 58mm * 21mm * 10mm (L*W*H)
Net weight: 13g - Instructions for use:
After power-on, the voltmeter displays, if you need to charge such devices as phone, Tablet PC, MP3, press the "Output Enable" button,
then the USB power indicator lights, USB output 5.0V;
if you need to turn off the digital display, press the "low power" button,
then enter low-power standby mode and USB output shutdown.
Voltmeter calibration method:
1.when the voltage meter display, press "Output Enable" button 2 seconds then release, voltmeter flashes.
2.Touch the "Output Enable" button, the voltage increases one unit,
touch the "Low Power" button, reduce one voltage reduction unit(one unit is less than 0.1V)
3.After the voltage adjustment is completed, please press the "Output Enable" button for 2 seconds then release, exit voltage calibration mode.
If power off, parameter setting will automatically save.
Applications:
1.Car / motorcycle battery voltage monitor or other voltage measurements
2.USB Charger for Mobile phone, MP3, Tablet PC or other electronic products
Please Note:
This module defaults to D+,D- shorted, compatible with most of cell phone charging,
if you need to install identification resistor such as for IPhone, please cut off the red line position
