Lifesafety Power RGS250-4D8/E Rackmount Power Supply
Overview
The RGS250-4D8/E is a 150W rackmount power supply designed to distribute regulated DC power to networked security endpoints and auxiliary devices in distributed surveillance deployments. It provides selectable 12VDC (12A) or 24VDC (6A) output—voltage flexibility that lets you match the power architecture of legacy and modern IP cameras, control modules, and access readers in the same cabinet without requiring separate supply chains.
Key Specifications
Output Configuration: Eight fused DC auxiliary outputs, each rated 3A maximum. Each output is independently assignable to Bus1 or Bus2, enabling segregated power domains for redundancy or load balancing across multiple device circuits.
Input & Conversion: AC input with ferrite filtering reduces EMI in sensitive RF environments—a practical detail in facilities with two-way radios or wireless access points sharing the same cabinet space. Single FPO bus architecture via single Flex Cable Kit (4 D8/D8P compatible connectors).
Compatibility & Integration
The RGS250-4D8/E integrates with Lifesafety Power D8 and D8P base modules and is compatible with systems using 12V or 24V DC endpoints. It functions as a standalone cabinet supply or as part of a multi-supply redundancy scheme when paired with PoE switches that require auxiliary DC for remote PoE injectors or distributed power nodes.
Installation Constraints
Rackmount form factor requires standard 19-inch cabinet space and AC mains availability. Eight 3A output fuses provide branch-level overcurrent protection—critical for segregating fault domains so a short on one endpoint circuit does not cascade to others. Auxiliary outputs must be wired according to voltage selection (12V or 24V); voltage selection is a one-time configuration during commissioning.
