Altronix R2416600ULCB CCTV Power Supply
Overview
The Altronix R2416600ULCB is a professional-grade 2U rack-mount power supply engineered for mid-to-large scale CCTV and access control installations. Delivering 24/28VAC output at 25A maximum current across 16 individually supervised Class 2 outputs, this unit consolidates power distribution for camera arrays, access control devices, and auxiliary security equipment into a single, space-efficient chassis. The R2416600ULCB operates on standard 115VAC input and integrates seamlessly into existing rack infrastructure, reducing panel clutter and simplifying troubleshooting during system deployment and maintenance.
Key Features
- 16 Supervised Class 2 Outputs: PTC (Positive Temperature Coefficient) protected outputs with independent supervision ensure fault detection and prevent cascading failures when a load is disconnected or shorted
- 24/28VAC Output at 25A: Full-current rating provides adequate headroom for mixed-load camera and device configurations without voltage sag under peak demand
- 115VAC Input: Standard North American mains voltage compatibility; no step-down transformer or special circuit preparation required
- 2U Rack Mount Form Factor: Compact vertical footprint fits standard 19-inch racks alongside switches, NVRs, and access control panels
- UL Listed & CE Marked: Dual regulatory compliance confirms product safety for use in commercial and institutional security installations
- Class 2 Rated Outputs: Inherent current-limiting and short-circuit protection meets NEC Article 725 requirements for low-voltage control circuits
Integration & Compatibility
Security integrators will recognize the R2416600ULCB as a drop-in replacement or primary power backbone for legacy analog CCTV systems, IP camera PoE injector farms, door controllers, card readers, and intercom panels. The 16-output design accommodates redundant power feeds to critical devices and supports daisy-chaining of auxiliary loads through distribution blocks. UL and CE certifications confirm compatibility with installations subject to commercial building codes and international electrical standards. Supervision capability allows monitoring platforms to log and alert on individual output faults, reducing service response time for field troubleshooting.
Electrical Specifications
Input rating of 115VAC ensures operation within standard branch circuit capacity (typically 15–20A circuits). The R2416600ULCB outputs 24/28VAC at a maximum aggregate current of 25A, with each of the 16 outputs individually fused and PTC-protected to prevent damage to downstream equipment. Class 2 output classification eliminates the need for conduit or additional insulation when running wiring to cameras and devices, reducing installation labor and material cost. All outputs remain isolated from the chassis ground, permitting flexible wiring topology without ground-loop concerns common in analog video systems.
Physical & Environmental Integration
The 2U height and standard rack-mount ears enable vertical stacking with other equipment in 42U and 48U cabinets. Power cord termination is internal, reducing the footprint in crowded rack spaces. The unit is suitable for indoor climate-controlled environments typical of server rooms, wiring closets, and security operations centers. Thermal design ensures reliable operation in standard HVAC conditions without external cooling or special ventilation provisions.

I have specified the Altronix R2416600ULCB on several moderate-scale CCTV migrations where analog and hybrid IP environments required centralized, supervised power distribution. The 16-output architecture scales well for facility expansions and provides the headroom needed when camera arrays are added incrementally over a project lifecycle.
Technical Highlights:
- Supervised Outputs: PTC protection and individual output supervision mean a single shorted camera feed will not take down the entire power rail—a significant operational advantage in multi-camera deployments.
- Compact Rack Footprint: 2U height preserves real estate in cabinets shared with edge switches, NVRs, and access control processors; the unit pulls 115VAC from standard branch circuits without additional service upgrades.
- Regulatory Dual Compliance: UL listing and CE marking eliminate certification delays for projects spanning North American and international markets.
Deployment Considerations:
- Plan wiring runs from the R2416600ULCB to cameras and devices with Class 2 cable (typically 18–16 AWG) to remain within code; this allows direct installation in walls without conduit.
- Verify incoming 115VAC circuit capacity and panel load; at 25A output, the supply will draw approximately 5–6A input current under full load, leaving margin on a standard 20A breaker.
- Use a dedicated power distribution block or terminal strip to organize the 16 outputs; label each with the corresponding camera or device ID to streamline future service calls.
For integrators managing mixed-voltage systems or facilities requiring rapid power scalability, the R2416600ULCB delivers proven reliability and simplifies the cabling and troubleshooting burden. Its supervision capability integrates naturally with modern monitoring systems that log device health and alert on faults in near real-time.
