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 combo2. High-performance, multi-purpose, intelligent and user-friendly design3. If you don’t need to enable the switch, just disconnect the pointed line4. Ultra-wide range of voltmeter: DC4. 5~40V5. 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 purposes7. 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: 13g9. Size: 58x21x10mmModule 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 burn3. With over-current and over-temperature protection4. With USB power indicator5. With wiring terminals, easy to access the line6. High efficiency, low rippleModule 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.Specification: Package Weight One Package Weight 0.03kgs / 0.07lb One Package Size 8cm * 5cm * 3cm / 3.15inch * 1.97inch * 1.18inch Qty per Carton 300 Carton Weight 10.00kgs / 22.05lb Carton Size 42cm * 32cm * 32cm / 16.54inch * 12.6inch * 12.6inch Loading Container 20GP: 620 cartons * 300 pcs = 186000 pcs 40HQ: 1439 cartons * 300 pcs = 431700 pcs
