Description

Lifesafety Power RD250-8 Rackmount DC Power Supply

Overview

The RD250-8 is a dedicated rackmount power supply designed to deliver redundant DC power to electrified locking hardware and access control systems in commercial security installations. It provisions either 12VDC at 20 amps or 24VDC at 10 amps — allowing you to match your lock voltage topology without oversizing. The eight dedicated egress lock outputs eliminate the need for separate relay modules in medium-scale access control deployments, simplifying both wiring and troubleshooting.

Compatibility

The RD250-8 integrates into rackmount DC power configurations paired with access control panels, electric strikes, magnetic locks, and egress hardware from vendors including Salto, HID, Honeywell, and Vivotek-compatible door management systems. Verify voltage and amperage requirements against your specific lock hardware before specifying.

Deployment Context

Deploy the RD250-8 in small-to-medium access control systems where centralized power distribution from a single rack eliminates point-load failures. The eight outputs accommodate typical multi-door entrances (lobbies, secured corridors, loading docks) without cascading power topology. Back-order status may affect availability — confirm lead time with your procurement contact.

Installation Notes

Mount in a standard 19-inch equipment rack. Wire input power to a dedicated 20-amp circuit breaker (12V configuration requires higher current capacity than 24V). Verify that branch-circuit amperage supports the supply's inrush current during cold start. Test all eight outputs under load before commissioning to confirm lock activation voltage at the farthest door.
