Lifesafety Power RD250/250 Rackmount Power Supply Distribution Enclosure
Overview
The RD250/250 is a compact 2U rackmount power distribution unit designed to centralize power delivery for networked security endpoints across distributed installations. It supplies 250W total capacity in dual configurations—20A at 12VDC or 10A at 24VDC—eliminating the need for multiple individual power adapters and reducing point-of-failure risk in larger deployments. The 16-output rear board simplifies wiring and consolidates management of power supply circuits for mixed-voltage environments.
Compatibility & Integration
The RD250/250 pairs with standard 12VDC and 24VDC endpoints including IP cameras, access control readers, door locks, and other security hardware requiring constant or backup power. The dual-voltage capability lets you run both 12V and 24V devices from a single rackmount chassis, reducing enclosure count in mixed-technology deployments. It integrates into PoE switch backup power architectures for sites where switch-sourced PoE is insufficient or unavailable.
Installation Context
Built for 19-inch standard racks, the RD250/250 occupies 2U of vertical space. The rear board consolidates fault monitoring, battery connections, and FAI (Fault Alert Input) supervision points, enabling centralized circuit diagnostics. Its 16-output configuration handles medium-scale distributed security networks without requiring external terminal blocks or secondary power panels. Front and rear accessibility simplifies troubleshooting and maintenance without displacing adjacent equipment.
When to Choose a Different Model
If your deployment exceeds 250W or requires higher amp-hour battery backup capacity, evaluate larger units in the Lifesafety Power rackmount family. For single-voltage or lower-density installations, compact wall-mount or DIN-rail units may be more cost-effective. Confirm your endpoint current draw and standby runtime requirements before final selection.
