HW-318 12V To 5V Buck Module DC-DC 3A DC Power Module LED Battery Car Voltmeter

1. Two-wire car voltmeter + 5.0V USB charging combo
2. High-performance, multi-purpose, intelligent and user-friendly design
3. If you don't need to enable the switch, just disconnect the pointed line
4. Ultra-wide range of voltmeter: DC4. 5~40V
5. The output current capacity of 5.0V, 2A is enough to meet various USB devices, and the voltage is very stable. This module is short-circuited by D+D- by default, which is compatible with most mobile phone charging, and reserves the installation position of various mobile phone identification resistors. , If you need to add identification resistance, please cut off the wire connecting D+ D-
6. Purpose: Ultra-wide input voltage, can be used for cars, battery cars, motorcycles, used to monitor the battery voltage, timely grasp the battery status, can be used for various voltage measurement purposes
7. Note: The power module will become hot during normal use. If you are mindful of this heat or are sensitive to heat, please take it carefully.
8. Weight: 13g
9. Size: 58x21x10mm

Module performance and highlights:
1. The output current capacity of 5V/2A (note: when the input voltage is 6.5~40V, the output voltage of 5.0V can be stabilized)
2. With reverse connection protection, reverse connection will not burn
3. With over-current and over-temperature protection
4. With USB power indicator
5. With wiring terminals, easy to access the line
6. High efficiency, low ripple

Module instructions:
After the module is powered on, the voltage can be detected in real time. When you need to charge mobile phones, Ipads, MP3s and other digital products, just touch the "output enable" button. At this time, the USB power indicator lights up and the USB outputs 5.0V voltage; When you need to turn off the digital tube, touch the "low power consumption" button, and the module enters the ultra-low power standby mode, and the USB output is also turned off accordingly.
