Lifesafety Power FPO150-2D8PE4M1 150W 16-Output Power Supply
The Lifesafety Power FPO150-2D8PE4M1 is a fixed-output, high-capacity power distribution unit designed for multi-camera and access control installations where you need to centralize power for a dozen or more devices from one supply point. With 150W total capacity and 16 individually protected auxiliary outputs, this unit reduces field wiring complexity and gives you granular control over individual circuit faults.
Key Features
- Dual-voltage primary output (12A @ 12VDC or 6A @ 24VDC): Choose the output voltage that matches your camera and door-control device mix. The 12VDC setting delivers 144W; 24VDC mode delivers 144W at half the current, reducing voltage drop across longer cable runs — critical if you're distributing power more than 100 feet from the enclosure.
- 16 independent Class 2 auxiliary outputs, each rated 2.5A: Each of the 16 auxiliary circuits is fused and isolated, so a short or overcurrent on one output won't cascade through the whole supply. For a typical door controller pulling 0.8A or a camera at 1.2A, this gives you headroom and protects adjacent devices if one fails.
- E4M1 enclosure with Mercury backplate: Galvanized steel construction rated for wall, cabinet, or DIN-rail mounting in indoor security rack environments. The Mercury backplate simplifies wiring by pre-terminating the main output and auxiliary distribution rails — you're not hand-wiring a terminal strip from scratch.
- Compact form factor: Fits standard 19-inch security cabinets and wall-mount boxes without dominating space, leaving room for an NVR, PoE switch, or access control panel in the same enclosure.
- 150W total capacity: Sufficient to power up to 16 mixed-draw devices (small PTZ domes, bullet cameras, access readers, or relay modules) without the need for cascaded supplies or daisy-chained PoE injectors.
- Fixed output (non-adjustable): No potentiometer tuning required; set once at installation and it stays stable. Reduces commissioning time and eliminates field drift complaints later.
Integration & Compatibility
This supply pairs naturally with IP security systems that require dedicated 12VDC or 24VDC rails separate from PoE infrastructure. It's often used in hybrid deployments where you have PoE cameras on a managed switch, but also outdoor access controllers, door strikes, or analog sensors that need hardwired 12 or 24V. Because each output is fused at 2.5A, you can safely connect devices with varying current draws without worrying about interaction between channels. The Mercury backplate simplifies installation in existing cabinet environments — no need for external terminal blocks or additional assembly.
When to Choose a Different Model
If you need adjustable voltage output or integrated UPS battery backup with automatic failover, consider a higher-capacity model in the Lifesafety Power catalog. If you're deploying only PoE cameras with a managed PoE switch, skip this supply entirely and use the PoE switch's built-in power budget. If you require 100+ watts of continuous 24VDC output for a large door-strike array, verify the 6A @ 24VDC limit meets your peak draw; a higher-wattage supply may be necessary.
Frequently Asked Questions
Q: Can I use the FPO150-2D8PE4M1 to power both cameras and door controllers simultaneously?
A: Yes. The 16 outputs are independent, so you can assign some channels to cameras (typical 0.8–2A each) and others to door readers or strikes (typically 0.4–1.5A each), as long as the total draw across all 16 channels doesn't exceed 150W (the primary output limit) and each individual output stays under 2.5A.
Q: What's the difference between the 12VDC and 24VDC output settings?
A: At 12VDC, you get 12A; at 24VDC, you get 6A. Both deliver 144W. Use 12VDC for shorter runs (under 50 feet) or low-impedance loads; use 24VDC for longer cable runs (100+ feet) to reduce voltage drop and wiring gauge requirements.
Q: Are the 16 outputs fused individually?
A: Yes. Each output is Class 2 power-limited at 2.5A, so a fault on one channel won't disable the others. This is essential in multi-device installations where you can't afford a cascade failure.
Q: Does the FPO150-2D8PE4M1 include battery backup?
A: No. This is a fixed-output supply without integrated UPS. If you need ride-through power during brief outages, you'll need a separate battery backup module or UPS in the cabinet.
Q: Is the Mercury backplate included in the unit?
A: Yes. The FPO150-2D8PE4M1 ships with the E4M1 enclosure and Mercury backplate pre-assembled, reducing installation labor.
Q: What mounting options are available?
A: The E4M1 enclosure supports wall mounting, cabinet mounting, and DIN-rail mounting via standard brackets (verify bracket availability with your installer or supplier).
The FPO150-2D8PE4M1 is a workhorse for integrators building hybrid security racks where you need centralized 12 or 24VDC distribution alongside PoE switches and NVRs. The 16 independent, fused outputs at 2.5A each eliminate the need for daisy-chained supplies or external terminal blocks, and the E4M1 Mercury backplate cuts assembly time significantly — you're not hand-soldering or crimping a custom terminal strip on site.
Technical Highlights:
- 150W total capacity with dual-voltage primary (12A @ 12VDC or 6A @ 24VDC): The 24VDC mode is a real asset for longer cable runs where voltage drop matters; 6A at 24VDC lets you use 16 or 18 AWG over 150+ feet without exceeding a 5% drop. At 12VDC, the 12A is overkill for most individual devices but valuable if you're powering a cluster of readers or relay modules near the cabinet.
- 16 Class 2 auxiliary outputs, each fused at 2.5A: This granularity is why integrators prefer this unit over a dumb bench supply. A short on one output—say, a wet door reader in a loading dock—won't cascade and take down your entire rack. Each channel is isolated, and diagnostics are simpler because you can kill power to one zone without affecting the others.
- Mercury backplate with pre-wired rail distribution: Saves 2–3 hours of assembly labor per unit. The terminal positions are laid out and clearly marked; you're screwing in wire, not building the distribution from raw components.
Deployment Considerations:
- No battery backup integrated. If you need UPS ride-through (especially for door strikes or access readers), this supply alone won't cut it—plan for a separate battery module or external UPS in the cabinet. Many integrators treat this supply as the primary distribution point and add a small 24VDC battery module on the 24V rail for critical circuits.
- Watch the 2.5A-per-output ceiling. A high-power PTZ dome drawing 2.8A on one channel will trip that circuit's protection; you'd need to split the load across two outputs or use a different supply. For multi-PTZ installations, verify current budgets before committing to this unit.
- The fixed output (no voltage adjustment) is a plus for stability and a minus for flexibility. If you inherit a site with mixed 12V and 24V equipment, you'll need to partition outputs carefully or accept that some devices will run on their non-native voltage (bad idea).
Deploy the FPO150-2D8PE4M1 in mid-scale security racks (4–8 cameras, 3–6 door readers/controllers) where you want a single, robust power node with fault isolation. It's not overkill for a small site, but it earns its space in larger cabinet installations where you'd otherwise be managing multiple supplies and external terminal blocks.
