DC 9V UPS Power Supply Module with Auto Battery Switchover, Stable Output Boost Converter Board for Router

DC 9V UPS Power Supply Module with Auto Battery Switchover, Stable Output Boost Converter Board for Router Description

DC 9V Output UPS ChargeBoost Control Board, 12W Max Why you need it Keeps essential devices running during power outages by automatically switching to battery power Charges your battery when input power is available and maintains stable output for continuous operation Protects your equipment and battery with multiple safety features Key benefits Auto charging and seamless switchover: Maintains power to connected devices without interruption Full protection: Input reverse connection, overheating, overdischarge, and shortcircuit protection Stable performance: Efficient boost design provides steady DC output to your load Wide utility: Ideal for powering routers, switches, mobile power projects, infrared alarms, and more Easy installation: Lightweight, compact PCB for flexible integration Function and performance Working voltage (input): DC 5.0V to 12.0V Output: DC 9V; up to 12W maximum power Output current: Up to 1A at full battery; delivers 8-9W as battery approaches depletion Battery support: 3.7V lithium or polymer battery up to 15Ah (battery not included) Power continuity: Automatically switches to battery during outages; lowbattery flashing prompt before protection shutdown Shortcircuit response: Automatic shutdown with recovery after recharging Shared ground design: Input and output can share the negative pole; use separate positive connections Compatibility and applications Network equipment: Routers, switches, and similar 9V devices Security and sensing: Infrared alarms and lowpower monitoring equipment DIY and mobile power: Power conversion and mobile power supply projects; small equipment backup where 9V DC is needed How to use 1) Connect the correct input voltage (DC 5.0V-12.0V) to the input terminals. 2) Verify the output with a voltmeter and ammeter. 3) Connect the battery to B+ and B (3.7V Liion or LiPo, up to 15Ah). 4) Connect your device to the DC 9V output. When the battery is fully charged, up to 1A can be supplied. As the battery nears depletion, 8-9W will be available. If the output is shortcircuited, the board shuts down and recovers after recharging. A flashing indicator alerts before lowpower protection shuts down the output.
