Lifesafety Power FPO250/250-3D83M8NLCE12M 250W Managed Power Supply
Overview
The FPO250/250-3D83M8NLCE12M is a 250W managed power supply delivering either 20A at 12VDC or 10A at 24VDC, depending on configuration. The unit provides 8 independent DC auxiliary outputs, each fused at 3A, with per-channel Bus1/Bus2 selectability. This design is purpose-built for security and access-control integrations where multiple IP cameras, door locks, or auxiliary devices require individually supervised, isolated power distribution from a single source. The managed output architecture allows integrators to segregate loads across redundant power buses, reducing single-point-of-failure risk on larger deployments.
Compatibility & Configuration
Each of the 8 outputs is independently selectable for Bus1 or Bus2 assignment, enabling flexible load distribution across two distribution buses without requiring separate power supplies. The 3A per-output fusing protects individual circuits without nuisance trips on transients. The dual-bus design is compatible with access-control panels and distributed power architectures that expect supervised auxiliary power rails. Verify your system's input voltage requirement (12V or 24V) before configuring; the unit is ordered with a specific voltage rating and is not field-switchable between them.
Installation Notes
Coordinate with your system's power distribution diagram to assign outputs to Bus1 or Bus2 according to redundancy and load-balancing requirements. Ensure DC load calculations do not exceed 3A per output (fused maximum) to avoid nuisance fusing during normal operation. Verify inlet AC supply capacity and grounding compliance with local electrical codes before installation. The managed output fusing provides per-circuit protection, but total draw across all 8 outputs must not exceed the unit's rated current (20A @ 12V or 10A @ 24V).
