Modul UPS 5V - 12V to 9V / 12V DC Module Charging Power Supply Control - 12V

Feature: Support charging and discharging at the same time Large current Small size High efficiency Support short circuit protection Specification: Product Name: UPS Voltage Converter Module Working Voltage: DC 5.0V-12.0V Output Voltage: DC 9V/DC 12.0V(Option) Output Power: 9W/12W Support Battery: 3.7V Lithium or polymer battery 15Ah(Max) (No include!) Working Temperature range: -40 -85℃ Working Humidity range: 0%-95%RH Size: 50*20*6.3mm Using Steps: Connect right input voltage at input terminal. Check output voltage by voltmeter and ammeter. Connect battery at B+ and B-. Note: Its max output current is 1A and can’t keep output 1A. The positive and negative poles of the input power supply cannot be reversed Otherwise the module will be damaged. Users can install a common anode Red-Blue LED by yourself as charging indicators. Blue light indicates whether there is a load at output. Keep Red is charging. There is no battery if Red flashing. Red OFF if charged. Due to the large current, it is recommended to use a thicker wire. Wire cross-section greater than 1.5 square millimeters. Please read use manual and description before use. Application: Ordinary power supply Battery charger Mobile power Power conversion Infrared alarm Network equipment such as switches Router Battery car modification
