Battery Charger

The AD2120CF series is a DC uninterruptible power supply (DC UPS) that combines an AC-DC switch-mode power supply, backup control circuitry, and a battery charger to provide stable, uninterrupted DC power. With a wide AC input range and TS35 DIN rail installation design, it is ideal for applications such as security monitoring systems, telecom systems, and environmental monitoring systems. It features built-in AC power failure dry contact alarm signals and low battery voltage dry contact alarm signals for real-time monitoring of operation. Additionally, the AD2120CF series includes comprehensive protection mechanisms such as overload protection, short circuit protection, overcurrent protection, reverse polarity protection, and low battery voltage shutdown, ensuring safe and stable system operation, especially in applications requiring long-term stable power supply.
