Lifesafety Power RGS250-4D8Z1 Rack-Mount Power Supply, 32 Fused Outputs
Overview
The RGS250-4D8Z1 is a 250W power supply designed for distributed IP camera and accessory installations in rack-mount environments. It delivers either 20A at 12VDC or 10A at 24VDC — sufficient to support mid-scale multi-camera deployments where individual endpoint power demand must be isolated and supervised. The 2U enclosure (19.00" W × 3.50" H × 20.50" D) fits standard 19-inch racks, making it practical for network closets and equipment rooms where space is constrained.
Power Architecture & Output Configuration
The unit features 32 DC auxiliary outputs, each independently fused at 3A. Each output is selectable for Bus1 or Bus2, allowing you to segregate power delivery across two independent supervision circuits — a critical design pattern when you need to monitor power integrity separately by zone or system segment. This dual-bus architecture prevents a single wiring fault from collapsing power to all endpoints simultaneously.
Compatibility & Integration Context
This supply pairs with systems requiring dedicated, supervised PoE switch backup or non-PoE powered endpoints (sensors, door controllers, strobes, auxiliary devices). The 32-output count and per-output fusing make it suitable for small-to-medium security installations where each device requires its own circuit protection and you need granular monitoring per output.
Installation & Mounting
The Z1 heavy-duty articulating bracket with integrated wire management secures the unit and organizes cable runs, reducing installation labor. The enclosure accommodates internal distribution terminal blocks and clearly marked output terminals for simplified field commissioning.
