Lifesafety Power RS250B-M16 Rackmount 250W Power Supply
Overview
The RS250B-M16 is a 2U rackmount power distribution unit designed to centralize power delivery across multi-camera deployments and IP-based security infrastructure. It delivers 250W total capacity with selectable output: 20A @ 12V or 10A @ 24V — accommodating both legacy 12V camera systems and modern 24V endpoints. A 12V secondary module with adjustable 5–18V output @ 4A max (Class 2 power-limited) serves auxiliary devices like door locks, access control readers, and alarm sensors. The 16-output managed enclosure structure (RS8 board × 2) allows per-port supervision and fault reporting, essential for identifying power supply failures in real time across distributed camera sites.
Compatibility
The RS250B-M16 is purpose-built for Lifesafety Power surveillance ecosystems and integrates into rackmount power supply architectures where centralized PoE switch backup and dual-voltage support are required. Verify specific board and firmware compatibility with your system integrator before procurement, as the unit's configuration depends on RS8 module pairing and battery backup topology.
Installation Notes
This is a 2U rackmount enclosure requiring standard 19-inch rack space. Dual RS8 boards provide redundancy and expansion capability. The R2U rear board manages fault detection, battery connections, and auxiliary power distribution. Integrators must size backup battery capacity separately based on load duration requirements and confirm voltage rail isolation if mixing 12V and 24V outputs in the same deployment.
