Lifesafety Power RGH75B-C8PZ 75W Power Supply with 8-Channel Relay Control
Overview
The Lifesafety Power RGH75B-C8PZ is a 75W regulated power supply designed for access control, lock management, and auxiliary device control in security installations. It delivers either 6A at 12VDC or 3A at 24VDC — sufficient to power a single IP camera or small cluster of networked endpoints alongside relay-controlled electromagnetic locks, door strikes, or intercom interfaces. The unit provides eight Class 2 power-limited relay outputs, each independently selectable for failsafe or failsecure operation, with rated throughput of 2.5A per relay. This separation of power delivery from relay control reduces wiring complexity in access panels and eliminates the need for secondary relay modules in single-door or two-door deployments.
Compatibility
The RGH75B-C8PZ integrates into access control systems requiring coordinated power and lock control — particularly installations where power supply and relay switching are co-located in a single enclosure. Verify compatibility with your access control panel's relay input voltage and contact rating (typically 12VDC or 24VDC trigger). Confirm relay amperage requirements do not exceed 2.5A per channel; multi-door or high-draw lock applications may require load distribution across multiple outputs or external relay modules.
Installation Notes
Each relay output is independently configurable for FAI (Fail As-Is) or failsafe/failsecure modes — set via hardware or controller programming depending on your access control software. Wire 24/7 backup power to the supply's battery input if UPS integration is required; the unit supports external battery connection for power-loss lock release scenarios. Class 2 power limiting at 2.5A per output protects against short-circuit conditions and reduces shock hazard in low-voltage installations. Secure the supply in a climate-controlled cabinet; confirm AC mains input voltage matches your site electrical infrastructure (typically 110–240V, auto-sensing).
