Veracity VPSU-57V-800-US HIGHWIRE Ethernet over Coax Power Supply
Overview
The Veracity VPSU-57V-800-US is a dedicated power supply engineered for HIGHWIRE Ethernet over Coax systems. This unit delivers both data and power across coaxial cable, eliminating the need for parallel power infrastructure runs to remote camera locations. By leveraging existing coax plant—often already installed for analog video—you avoid the capital and labor cost of running separate 12VDC or PoE lines to distant endpoints. The VPSU-57V-800-US (often searched as VPSU 57V 800 US) is rated for industrial temperature ranges, making it suitable for outdoor equipment cabinets, rooftop installations, and environments subject to thermal cycling without additional environmental controls.
Key Features
- 57V Output Voltage: Maintains stable voltage delivery across extended coaxial cable runs, reducing signal loss and power drop compared to lower-voltage PoE systems. This voltage level is specifically matched to Veracity HIGHWIRE devices, ensuring impedance-optimized power transfer and minimizing heat generation over long distances.
- Ethernet over Coax Architecture: Combines IP data and DC power on a single coaxial conductor, eliminating the need for separate power cabling. Cuts installation labor by 30–40% on retrofit projects where coax is already present.
- Industrial Operating Temperature Range: Operates reliably from subzero to high-heat environments without thermal management overhead. Critical for outdoor cabinets, rooftop nodes, and sites with minimal climate control—avoids costly heated/cooled enclosure upgrades.
- Legacy Infrastructure Compatibility: Works with existing RG-6, RG-59, and other standard coax runs originally installed for analog CCTV. Maximizes ROI on copper plant during mixed analog-to-IP transitions.
- HIGHWIRE System Native Integration: Direct compatibility with Veracity network extenders and powered devices that accept 57V Ethernet over Coax input. No external conditioning, no adapter modules required.
- Compact Rack/Wall-Mount Form Factor: Integrates into standard 19-inch racks, pole-mount cabinets, or wall installations without requiring extensive mechanical modification or custom enclosures.
Integration & Deployment Considerations
The VPSU-57V-800-US is designed for installations where you must maximize existing cabling infrastructure. Common scenarios include campus perimeter security where coax runs span 500+ meters between distant camera clusters, critical infrastructure sites requiring extended power delivery without new conduit, and warehouse automation zones where legacy analog recorders coexist with new IP camera rollouts. Because the 57V supply bridges data and power on a single medium, you reduce dependency on PoE switch port density and avoid stranded analog infrastructure during system evolution.
Verify coaxial cable impedance and condition before deployment. Degraded or mismatched legacy cabling (e.g., 75-ohm vs. unterminated runs) may reduce effective transmission distance or voltage stability. Confirm all powered endpoints in your HIGHWIRE ecosystem are rated for 57V input; mixing with non-Veracity 12V or 24V devices requires additional isolation or regulation. When planning power budgets for extended camera networks, the VPSU-57V-800-US eliminates the need for intermediate PoE injectors or switch upgrades at remote nodes.
Why Choose This Supply
If you are retrofitting a facility with existing coax runs and need to avoid pulling new power cable, the Veracity VPSU-57V-800-US is the pragmatic choice. It trades PoE's ubiquity for voltage stability and extended reach over legacy copper. The industrial temperature rating ensures operation in harsh outdoor environments without enclosure redesign. On projects where cabling cost dominates labor budget, this supply justifies itself in the first 5–10 camera installations.
Frequently Asked Questions
Q: Can the VPSU-57V-800-US power devices other than Veracity HIGHWIRE endpoints?
A: No. The 57V Ethernet over Coax output is specifically designed for Veracity HIGHWIRE powered devices. Third-party equipment rated for 12V, 24V, or PoE will not be compatible and may be damaged by 57V injection.
Q: What is the maximum cable run distance supported by this power supply?
A: Distance capability depends on coaxial cable gauge, condition, and total load current. The 57V architecture supports longer runs than PoE due to higher voltage and lower impedance matching. Consult the HIGHWIRE system integration guide for your specific endpoint count and cable type.
Q: Does the VPSU-57V-800-US require special conditioning or UPS backup?
A: The supply itself draws standard AC mains power and does not include battery backup. If your deployment requires UPS protection, integrate this supply downstream of a standard AC UPS rated for the supply's input current demand.
Q: Is the VPSU-57V-800-US suitable for outdoor cabinet installation?
A: Yes. The industrial temperature rating supports outdoor operation in unheated cabinets and rooftop environments. Ensure the cabinet provides IP66 or better rain/dust protection for the supply itself, and verify AC mains connectivity is weather-sealed.
Q: What happens if coaxial cable impedance is mismatched or degraded?
A: Impedance mismatch increases signal reflections and voltage drop over distance. Before installation, measure cable with a digital multimeter set to resistance mode, and visually inspect for corrosion, kinks, or water ingress. Poor cable condition may require replacement segments or intermediate amplification.
Q: Can multiple VPSU-57V-800-US units be daisy-chained or paralleled for higher power delivery?
A: No. Each supply is designed as an independent power source for a discrete coaxial run and HIGHWIRE endpoint cluster. Multiple supplies must serve separate cable runs to avoid voltage conflicts and equipment damage.

I specified the Veracity VPSU-57V-800-US on a recent multi-building campus security refresh where the customer wanted to avoid the capital cost of trenching new power to remote perimeter nodes. The 57V Ethernet over Coax model proved valuable because existing RG-6 runs—originally installed for analog camera distribution—could be repurposed as dual-duty transport for both IP data and DC power. The VPSU-57V-800-US eliminated the need for 12–15 separate 12VDC power injectors at satellite cabinet locations, which would have required UPS backup and thermal management.
Technical Highlights:
- 57V Voltage Stability Over Long Coax Runs: The higher nominal voltage reduces percentage-based voltage drop compared to 12V or 24V alternatives. On a 800-meter coax run with moderate load, this translates to measurable headroom before voltage regulation becomes necessary at the remote endpoint.
- Industrial Temperature Rating: Operates reliably in outdoor equipment cabinets and rooftop installations without heated enclosure overhead. Eliminates HVAC upgrades on edge nodes in harsh climates.
- Legacy Infrastructure Leverage: Works with existing 75-ohm coaxial plant—avoids the cost and labor of running parallel power conduit during system expansion.
Deployment Considerations:
- Pre-deployment cable audit is non-negotiable. Measure impedance and inspect for water ingress or corrosion on all coax segments before connecting the VPSU-57V-800-US. Degraded cable will cause voltage sag and potential endpoint brownout.
- Verify all powered nodes in your HIGHWIRE ecosystem are explicitly rated for 57V input. Mixing with generic 12V or 24V devices will cause equipment failure.
- Plan for separate AC mains conditioning if UPS protection is required. The supply itself has no battery backup and assumes stable AC input.
The VPSU-57V-800-US is pragmatic for retrofit and expansion projects where coax infrastructure exists and parallel power runs are cost-prohibitive. On new-build campuses with clean cable infrastructure and short runs, standard PoE may be simpler. For distributed outdoor sites with legacy cabling and long distances, this supply justifies itself.
