DC Power Supply Unit With Battery Charger

24VDC 15A Power Supply Unit with Built-in Battery Charger & Dual Contactor Outputs

This robust 24VDC power supply unit delivers a reliable 15A output and features a built-in intelligent battery charger, making it ideal for mission-critical applications. Designed for uninterrupted operation, it seamlessly switches to battery backup during AC power outages—no external switching or wiring required. Just connect your battery directly for immediate integration.

The unit includes two built-in 24VDC contactor outputs, each rated at 50A, eliminating the need for external contactors. A 50A protective fuse is also integrated, providing overcurrent protection for downstream equipment like power amplifiers—ensuring system reliability and minimizing the risk of damage.

For added functionality, a 24VDC output trigger activates during AC failure, allowing connection to external alert systems such as buzzers, LED indicators, or emergency interfaces that require instant activation.

Installation is simplified with a plug-and-play design, reducing setup time for both experienced installers and first-time users. All core functions are internally configured, minimizing reliance on extra accessories and ensuring a cleaner, more organized rack layout that’s easy to maintain.

The built-in charger features advanced battery protection mechanisms including low-voltage disconnect and overcharge current limitation. These safeguards help prevent premature battery wear due to accidental misconfiguration or prolonged idle commissioning periods—particularly when systems are tested before end-user occupancy.

This all-in-one solution is purpose-built for professional environments that demand clean integration, minimal setup complexity, and continuous, dependable power. Just prepare your cables and connect—everything else is ready to go.
