Lifesafety Power RD150-16/E 150W Rackmount Power Supply Distribution

The RD150-16/E is a 2U rackmount power distribution enclosure designed for small-to-medium security and access control installations where centralized, supervised power management reduces field service calls and simplifies troubleshooting. It accepts 220VAC input and outputs selectable 12VDC or 24VDC—critical for deployments mixing legacy 12V sensors or readers with newer 24V devices on the same infrastructure.

Core Specifications

Power Budget: 150W total capacity supports up to 12A at 12V or 6A at 24V. For point-of-view context: a typical IP door strike draws 0.8–1.2A; a PoE injector module draws 0.5–1A. This supply handles 10–15 moderate-draw accessories before auxiliary supply becomes necessary.

Distribution Architecture: Two fused front boards (8 zones each) and 16 rear outputs isolate circuit failures—if one zone trips, the remaining 15 stay live. This supervised design is essential on life-safety and critical-access circuits where a total power loss triggers unnecessary alarms.

Form Factor: 2U height fits standard 19-inch server racks alongside network switches, NVRs, or UPS units. Rear board also carries RD fault signaling, FAI (Fault Alert Input), and battery backup connections—supporting 12V sealed-lead-acid or lithium UPS modules for siren/lock holdover during main power loss.

Typical Deployment

Install where centralized 24V distribution serves access control panels, door sensors, motion detectors, and IP intercom power taps. The RD150-16/E eliminates distributed wall-mounted supplies and gives integrators a single point to supervise and troubleshoot power faults—reducing downtime on multi-door or multi-zone projects.

Decision Points

Choose this model if you need:

Supervised 12V or 24V distribution in a compact rack-mount package

Fused zone isolation to protect downstream circuits from short-circuit cascades

Battery backup terminal connections for emergency power holdover

If your installation requires >150W continuous draw, evaluate larger Lifesafety Power supply families. If distributed power at each device is preferable to centralized management, individual power supplies may reduce wiring complexity.
