MEAN WELL PSC-100B-C 100W AC/DC Power Supply with Integrated Battery Charger, 27.6V DC 2.4A, UPS Function, Lead-Acid Charging

Industrial-grade 100W AC/DC power supply with integrated battery charger, delivering 27.6V DC at 2.4A for 24V lead-acid battery systems. The PSC-100B-C combines a regulated power supply and a smart charger in one chassis-mount unit, ensuring uninterrupted DC power for security, access control, and backup applications.

Advantages

Built-in UPS function detects AC failure and switches to battery seamlessly, preventing downtime. Intelligent 3-stage charging (bulk, absorption, float) extends battery life for gel, AGM, and flooded lead-acid types. Comprehensive protections include short circuit, overload, over voltage, battery low, and reverse polarity. Free air convection cooling ensures silent operation, while LED indicators provide clear status of AC OK, battery full, and battery low.
