12V 2A 24W DC UPS Power Supply Control Board Module V4.0L

The 12V 2A DC Uninterrupted Power Supply (UPS) Control Board V4.0L is an essential power management module designed to provide seamless backup power for your 12V electronics during outages. Engineered for reliability, it effortlessly manages power switching between a main 12V DC input and a backup 2S (7.4V/8.4V) lithium battery pack. With a rated power output of 24W and peak handling up to 30W, this module ensures your critical systems stay online without a glitch.

Perfect for makers and engineers, this UPS board is highly suitable for backing up Wi-Fi routers, security cameras, IoT sensor nodes, and microcontroller projects involving Arduino or ESP32. It features an onboard 500mA continuous charging circuit to keep the backup battery topped up while the main power is active. Its compact footprint and straightforward integration make it an ideal choice for custom automated enclosures and uninterrupted remote hardware setups.

Features:

• Seamless Power Switching: Instantly transitions to battery power when main input fails, ensuring zero downtime.
• High Power Capacity: Supports up to 2A continuous output current with a rated module power of 24W (30W peak).
• Integrated Charging: Features a built-in 500mA constant current charging circuit for the connected battery.
• Battery Compatibility: Designed specifically for 2S 7.4V-8.4V Li-ion or LiPo battery packs (up to 6Ah capacity).
• Compact & Efficient: Small board profile optimized for integration into tight router or IoT device enclosures.
