Lifesafety Power FPO250/250-B10010D8NLCE8M2 250W Dual-Output Power Supply
Overview
The FPO250/250-B10010D8NLCE8M2 is a 250W power supply with dual selectable outputs—20A at 12VDC or 10A at 24VDC. Eight independent DC auxiliary outputs provide 3A per channel, each selectable to serve either Bus 1 or Bus 2, allowing flexible distribution to multiple IP cameras, access control readers, alarm panels, and auxiliary devices in a single cabinet. The E8 enclosure (36H × 30W × 6.5D inches) mounts vertically and includes a 16-position DIN-rail mercury back plate for organized output termination. This configuration addresses the common integrator challenge: powering diverse 12V and 24V endpoints from one supply without cross-voltage contamination or excessive circuit splitting.
Compatibility
The dual-bus output architecture supports mixed-voltage deployments typical in security installations. Each of the 8 auxiliary outputs independently switches between Bus 1 (primary voltage rail) or Bus 2, enabling you to power 12V devices from one bus while 24V equipment draws from the other without additional external relays. This suits integration with legacy 12V cameras, newer 24V PoE infrastructure, 24V solenoid locks, and 12V siren modules in the same cabinet. Output assignment occurs at installation via DIN-terminal configuration; no field firmware updates required.
Installation Notes
The 3A per-output fusing provides branch circuit protection for each auxiliary load, reducing the need for external fused distribution blocks. Integrate with supervised power monitoring systems using the included quick guides for E8 enclosure, D8 supervision module, B100 battery backup interface, and NLC network loss configuration. The 6.5-inch depth allows cabinet mounting alongside PoE switches and video recorders in standard 19-inch racks. AC input wiring and DC output termination require standard terminal crimp connectors; consult the FPO75-250 combo manual for detailed commissioning sequences.
