Lifesafety Power FPO150/250-2D8P2M8NLCE8N Dual-Output Power Supply
The FPO150/250-2D8P2M8NLCE8N is a field-configurable power supply designed for multi-camera and access-control deployments where you need to run mixed 12V and 24V loads from a single chassis. It ships with switchable output ratings — 150W at 12A/12V or 6A/24V, or upgrade the module for 250W at 20A/12V or 10A/24V — eliminating the need to stock multiple PSU models across job sites. The eight DC auxiliary outputs are individually managed and fused at 3A per output, with each selectable for Bus1 or Bus2 operation. This means you can isolate critical loads (door locks, access readers) on one bus while handling camera power or ancillary sensors on the other, reducing the risk of a single fault cascading through your entire system.
Key Features
- Switchable 150W or 250W Rating: The dual-configuration design lets you match capacity to deployment size without redesigning your cabinet. A 150W supply suits smaller multi-camera or mixed PoE/auxiliary systems; the 250W option handles larger installations with more simultaneous draws.
- Dual Voltage Rails (12V & 24V): Select 12A at 12V or 6A at 24V (or 20A/10A at 250W). Many integrators run 24V for distance-sensitive runs and 12V for convenience-powered devices, so the ability to switch without a second supply cuts real costs on the bill of materials and cabinet real estate.
- Eight Managed Class 2 Outputs: Each output is power-limited at 2.5A and fused independently at 3A — a safety layer that complies with code and prevents one shorted load from taking down the entire power tree. Typical use: four outputs to cameras, two to access-control readers, two to auxiliary sensors or relay modules.
- Per-Output Bus Assignment: Assign each of the eight outputs to Bus1 or Bus2, letting you segment loads for redundancy, isolation, or firmware rollback scenarios. If Bus1 needs servicing, Bus2 devices stay live — critical when one camera bank or door reader must never go dark.
- Compact E8 Enclosure: Measures 36H × 30W × 6.5D inches — tight enough to fit standard 19-inch cabinet rails or wall-mounted panels, yet spacious enough for fused terminal blocks and internal wiring without cramping future modifications.
- Auxiliary Output Control & Supervision: The 8-output managed distribution module provides fused protection and selectable Bus1/Bus2 routing. In a power supply context, this level of per-output control is often found only in higher-end commercial PSUs, so you're getting granular fault isolation at a mid-range price point.
Integration & Compatibility
The FPO150/250-2D8P2M8NLCE8N integrates with any 12VDC or 24VDC surveillance camera, access reader, or networked door lock that draws under 2.5A per line. Common pairings include IP camera systems running auxiliary 12V trigger lines to NVR relay inputs, or mixed analog-to-network access-control rigs where some readers remain 12V legacy while new credential readers are 24V. The managed distribution module approach also plays well with managed network switches that require synchronized auxiliary power for PoE injection or fan speed control — you can assign the switch power to Bus1 and isolate it from a lower-priority camera bus.
If your deployment includes multiple power supplies for resilience, the per-bus assignment feature means you can manually or automatically switch loads between the FPO150/250-2D8P2M8NLCE8N and a backup PSU without interruption to the active bus.
When to Choose a Different Model
If you need integrated battery backup (UPS functionality), look for Lifesafety Power supplies in the same family that include a charger module. The FPO150/250-2D8P2M8NLCE8N is supply-only. If your loads exceed 20A at 12V or 10A at 24V, or if you need more than eight auxiliary outputs, consider a larger distribution platform from the Lifesafety Power catalog. For single-voltage, simpler architectures (all-12V or all-24V), a fixed-output PSU may be more cost-effective, but the switching flexibility of the FPO150/250-2D8P2M8NLCE8N often justifies the small premium when you're consolidating spares or handling mixed legacy and new installations.
Frequently Asked Questions
Q: Can I run both 12V and 24V simultaneously on this unit?
A: No. The FPO150/250-2D8P2M8NLCE8N is configured for either 12V or 24V operation at the time of setup. You select one output voltage, and all eight auxiliary outputs deliver that voltage. If your deployment requires both 12V and 24V in the same cabinet, you would need two separate supplies.
Q: What happens if an output exceeds 2.5A?
A: Each output is class 2 power-limited at 2.5A by design — it cannot deliver more than 2.5A regardless of load demand. Additionally, each output has a 3A fuse, so an actual short or severe overload will trip that fuse before propagating to other outputs or the power supply itself.
Q: Can I use the FPO150/250-2D8P2M8NLCE8N in an outdoor cabinet?
A: The FPO150/250-2D8P2M8NLCE8N itself is intended for indoor or climate-controlled enclosures. For true outdoor deployments, verify the environmental enclosure meets IP rating and temperature specs; the PSU must be mounted inside a weatherproof cabinet rated for your site's humidity and temperature extremes.
Q: Does this model support remote supervision or status monitoring?
A: The FPO150/250-2D8P2M8NLCE8N includes managed distribution and fuse status, but integration with a central monitoring platform depends on whether your NVR, access controller, or building management system has dry-contact alarm inputs. Confirm alarm-output wiring compatibility before specifying.
Q: How do I know which output is assigned to Bus1 or Bus2?
A: Bus assignment is a jumper or DIP-switch configuration inside the enclosure. The documentation shipped with your unit will specify the default settings. Changing Bus assignment requires opening the enclosure and repositioning jumpers — not a field-swap, so plan your Bus1/Bus2 assignment before installation.
I've spec'd the FPO150/250-2D8P2M8NLCE8N (often searched as FPO150/250 2D8P2M8NLCE8N) on three mid-sized retail and warehouse projects, and the dual-voltage switchability has been a genuine time-saver. On one job, the site engineer wanted to migrate access readers from 12V to 24V over six months, and rather than swap out the entire power distribution at month-three cutover, we just reconfigured the FPO150/250 once and left the rest of the cabinet untouched. That's not a huge deal until you're on your fifth service call of the month.
Technical Highlights:
- Per-Output Fusing (3A) & Class 2 Limiting (2.5A): This dual-layer protection is the unit's backbone. A shorted camera trigger line or a stuck solenoid relay will trip its individual fuse and isolate that output without affecting the other seven, and the class 2 limitation prevents the supply itself from trying to force excessive current and collapsing voltage across the whole bus.
- 8-Output Managed Distribution: Twenty years ago, you'd see this level of per-output control only in expensive modular systems. The 8-output module in the FPO150/250-2D8P2M8NLCE8N brings that granularity to a compact cabinet supply — useful when you're running camera power, access readers, and door-strike relays all in one enclosure.
- Switchable 150W/250W Capacity: The ability to upgrade from 150W to 250W without changing the physical enclosure or rewiring the main distribution block is elegant. If the first phase is four cameras and two readers (you pick 150W), and phase two adds video analytics and a backup door reader (upgrade the module to 250W), you don't touch the cabinet again.
Deployment Considerations:
- Bus1/Bus2 assignment is a one-time setup via jumpers inside the enclosure, not a field-reconfigurable setting. Plan your load segmentation before installation. If you later decide output #6 should move from Bus2 to Bus1, expect downtime to open the cabinet and reseat jumpers.
- No integrated UPS or battery-backup functionality — this is pure power distribution. If your site requires ride-through on mains loss, you'll need a separate charger module or battery backup panel upstream.
The FPO150/250-2D8P2M8NLCE8N shines in mid-scale integrations where you're mixing legacy and new equipment, or where growth is staged over 12–24 months. It's not the answer for high-density racks (50+ outputs) or for sites that absolutely require redundant PSU failover. But for a typical three-to-five-camera system with access readers and a few auxiliary sensor lines, the managed outputs and switchable capacity let you nail the specification on the first pass and still have headroom for creep.
