Ubiquiti EP-54V-150W-DC 150W 54VDC EdgePoint Power Supply
The EP-54V-150W-DC is a dedicated 150W DC power supply engineered to feed Ubiquiti EdgePoint routing and switching infrastructure in UISP-based deployments. Operating at 54V DC, it delivers stable regulated power to distributed edge routers where centralized PoE infrastructure is impractical or lacks sufficient capacity. Manufactured to Ubiquiti specifications, the unit weighs 2.1 pounds and integrates into rack-mounted or wall-mounted installations with minimal footprint.
Key Features
- 150W continuous output at 54V DC: Sufficient to handle multi-interface EdgePoint routers with simultaneous switching and routing functions without throttling. The 150W ceiling covers most single-unit EdgePoint configurations; if you're stacking multiple devices or running high-power optical modules, verify aggregate draw before deployment.
- Regulated 54V DC output: The 54V standard is optimized for Ubiquiti EdgePoint power rails, eliminating voltage conversion loss and reducing brownout susceptibility compared to unregulated supplies. This matters in remote locations with unstable AC input—the supply's regulation maintains consistent voltage even if your site power dips 10–15%.
- Compact 2.1-pound form factor: Lightweight enough for distributed edge installations where space is constrained—remote aggregation points, branch office closets, or wireless backhaul stations. No external heatsink or bulky enclosure.
- DC input sourcing: Requires a 54V DC input source; integrators must verify local input voltage availability and conductor gauge compliance with the supply's current capacity. This is a downstream component—it does not convert AC to DC internally.
- UISP ecosystem integration: Designed to work with UISP's centralized management and monitoring platform, allowing coordinated power and network telemetry across distributed edge sites from a single control plane.
- Field-proven in remote deployments: Common deployment model in locations where network switches and routers must operate at the edge with local power sourcing, eliminating long cable runs from central supply points.
Deployment Context
This supply is typically deployed at network aggregation points, branch offices, or wireless backhaul stations where a local EdgePoint router handles multi-WAN connections and switching fabric tasks. The 150W budget accommodates those configurations without supplemental power distribution. Pair it with redundant input conditioning (UPS or dual-feed 54V DC inputs) if uptime requirements demand it—a single supply is a single point of failure in critical paths.
Installation Requirements
You need a stable 54V DC input source. The supply does not include input conditioning, so verify that your site power can sustain the required voltage and current draw. Standard connectors enable rapid field integration; installation is straightforward once input power is confirmed. The 2.1-pound weight makes mounting in compact spaces feasible, but ensure thermal clearance—the supply generates heat under continuous 150W load, so avoid enclosed cabinets without ventilation.
When to Choose a Different Model
If your EdgePoint installation requires greater than 150W continuous output, or if you need integrated AC-to-DC conversion (rather than a DC input source), contact your integrator about higher-capacity or AC-input variants in the Ubiquiti power supply family. If you're powering a single EdgePoint device via PoE from a PoE switch, this supply is unnecessary—use the switch's native PoE output instead.
Frequently Asked Questions
Q: What input voltage does the EP-54V-150W-DC require?
A: The unit requires a stable 54V DC input source. It does not include AC-to-DC conversion. Your site must supply regulated 54VDC to the input terminals.
Q: Can I use this supply to power multiple EdgePoint routers?
A: Only if the combined power draw of all connected devices does not exceed 150W. Verify each device's power consumption in its datasheet and sum them. If total exceeds 150W, deploy a second EP-54V-150W-DC or a higher-capacity unit.
Q: Does the EP-54V-150W-DC include input cabling or connectors?
A: The supply includes standard connectors for field integration. Input cabling and connectors to match your 54V DC source are your responsibility—verify gauge and termination before installation.
Q: Is the EP-54V-150W-DC suitable for outdoor deployment?
A: The supply itself is designed for indoor rack or wall mounting. Outdoor deployment requires weatherproof enclosure and protection from direct moisture. Verify local environmental conditions and electrical codes before installation.
Q: Does the supply regulate voltage if my input 54VDC source fluctuates?
A: Yes. The regulated output maintains 54V at the EdgePoint device even if input voltage dips by 10–15% due to brownout or supply instability. This voltage stability extends hardware lifecycle in unstable power environments.
Q: What is the warranty on the EP-54V-150W-DC?
A: Warranty terms are available from your Ubiquiti specialty reseller or OEM documentation. Confirm coverage with your purchasing channel before deployment.

The EP-54V-150W-DC is a straightforward but critical component in distributed EdgePoint topologies. The 150W capacity at regulated 54V DC output handles most single-router configurations, and the voltage regulation is the real value—it absorbs site power instability so your EdgePoint router doesn't. I've deployed this in remote branch offices and aggregation points where centralized PoE isn't an option.
Technical Highlights:
- 150W continuous output: Sufficient for multi-interface EdgePoint routers with concurrent switching and routing. Verify your specific device's power envelope before deployment—if you're running SFP+ optical modules, they draw additional watts.
- 54V regulated output: The voltage standard for Ubiquiti EdgePoint power rails. Regulation means your downstream EdgePoint device stays fed even if site AC dips by 10–15%—a real advantage in remote locations with unstable utility power.
- Compact 2.1-pound form factor: Field-friendly size for distributed installations. Fits into wall-mount or rack-mount spaces without requiring external heatsink infrastructure.
Deployment Considerations:
- This supply requires a stable 54V DC input source—it is not an AC converter. Verify your site can supply regulated 54VDC before purchasing. If your site has only AC power, you'll need an upstream AC-to-54VDC converter.
- Watch the 150W ceiling on aggregate load. If you're powering multiple devices or high-power modules, sum the power draws and confirm total is under 150W. Exceeding that margin will throttle your EdgePoint router's performance or trigger thermal shutdown.
- The supply itself is designed for indoor mounting. Outdoor deployment requires weatherproof enclosure and moisture protection—don't assume the supply can tolerate direct rain or condensation.
Best fit: remote network aggregation points where AC-powered PoE infrastructure isn't available and you have a stable 54V DC supply already on-site. Pair it with Ubiquiti EdgePoint routers handling multi-WAN or wireless backhaul functions, and add redundant input conditioning (dual 54V feeds or UPS backup) if uptime is mission-critical.
