Lifesafety Power RGL75-D8Z Rack-Mount Power Supply
Overview
The RGL75-D8Z is a 75W, 2U rack-mount power supply designed to distribute regulated DC power across eight independently fused auxiliary outputs. Each output is field-selectable for Bus1 or Bus2 operation, delivering either 6A at 12V or 3A at 24V depending on your system voltage requirement. This compact form factor fits standard 19-inch racks and solves the core problem: centralizing clean, regulated power for access control nodes, readers, locks, and field devices without tangling individual wall-mount supplies throughout your installation.
Compatibility
The RGL75-D8Z integrates with Lifesafety Power control systems and bus-based access control architectures that require dual-bus or single-bus distribution. Confirm your system's Bus1/Bus2 topology and DC voltage requirement (12V or 24V) before selecting output assignments. Eight fused channels allow you to power up to eight independent 3A/24V or 6A/12V field devices per output—typical for reader/lock combinations, auxiliary relays, or sensor nodes in mid-scale deployments.
Installation Notes
Mount the RGL75-D8Z in a standard 19-inch rack using the included bracket. The unit measures 19.00″W × 3.50″H × 20.50″D and occupies 2U vertical space. The Z-bracket wire management arm keeps field wiring organized and reduces strain on terminal blocks. Each of the eight DC outputs is fused at 3A—exceeding this limit on any single output will trip the fuse, protecting downstream devices. Verify supply voltage (AC input) and confirm Bus1/Bus2 jumper positions before energizing. Use stranded copper wire rated for the expected current draw on each channel.
