Altronix R2416CB220 16-Output 24/28VAC Rack-Mount CCTV Power Supply
Overview
The Altronix R2416CB220 is a 220VAC-input, rack-mount AC power distribution unit purpose-built for CCTV deployments where you need to centralize camera power in a 2U footprint. It delivers 24VAC at 8A or 28VAC at 7A across sixteen independently PTC-protected outputs — the kind of distribution architecture that keeps a single shorted camera from taking down an entire wing of coverage. If you're commissioning a mid-to-large camera system in a European-voltage or international facility, or any domestic site wired for 220VAC, the R2416CB220 slots cleanly into a standard 19-inch EIA rack without a step-down transformer between the panel and your cameras.
Altronix has been producing Altronix power supplies for the professional security market for decades, and this unit carries CE, TAA, NDAA, and BAA compliance — a combination that matters for government, federal, and DoD-adjacent installations where supply-chain documentation is as important as the hardware itself.
Key Features
- Sixteen PTC-Protected Outputs (2.5A max each): Each of the 16 outputs is individually protected by a self-resetting PTC fuse. A fault on one circuit clears automatically once the load is removed — no pulling fuses or resetting breakers per port. At 24VAC, each output supplies up to 0.5A per device (2.5A max per port); at 28VAC, 0.4375A per device. This lets you mix cameras and accessories across the distribution rail without fear of cascade failures. Check your CCTV power supply sizing against your per-camera draw before populating all 16.
- Dual Voltage Output — 24VAC or 28VAC: The unit ships with a selectable output voltage. 24VAC is the standard rail for most CCTV cameras and PTZ units; 28VAC supports camera heater elements and accessories that need the extra headroom. Both modes deliver 200VA of total capacity — run the math on your camera count and heater draw before committing to a mode.
- 220VAC / 50-60Hz Input at 1.0A: Designed for 220VAC single-phase input — standard in most international installations and common in commercial electrical panels in North America. The 1.0A input draw means a 220VA system AC requirement; verify your panel circuit can sustain this under continuous load in a 24/7 surveillance environment.
- Illuminated Master Circuit Breaker with Manual Reset: The front-panel master power disconnect is illuminated so you can confirm live status from across the rack room. Manual reset means a qualified technician must clear and restore power intentionally — no accidental restarts during maintenance. Combine this with the per-output LEDs (one per channel) to diagnose faulted outputs without pulling the unit.
- Sixteen Per-Output Power LEDs: Each output has its own status LED. In a rack with 16 cameras, this is a real time-saver during commissioning and fault isolation — you can see at a glance which circuits are live and which have tripped, without a multimeter or crawling cable runs.
- Surge Suppression Built In: Integrated surge suppression on the output side reduces the risk of transient spikes — from lightning on outdoor camera runs or inductive kick from PTZ motors — damaging connected equipment. This is not a substitute for proper grounding and shielded cable on long outdoor runs, but it adds a measurable layer of protection.
- Removable Terminal Blocks with Locking Screw Flange: Wiring to removable, locking terminal blocks means you can pre-wire the output harness before the unit is racked, or swap the unit without cutting and re-terminating every camera run. This matters on retrofit jobs where pulling all cables at once isn't an option.
- 3-Wire Grounded Line Cord: Ships with a grounded line cord — a basic but important compliance point for commercial electrical inspections. Confirm your facility's 220VAC receptacle type before installation.
- NDAA / TAA / BAA / CE Compliant: All four agency listings verified for this SKU. NDAA Section 889 compliance is a hard requirement for federal and state government camera installations. TAA and BAA compliance extend the eligibility to GSA schedule and Buy American Act contracts. CE marking satisfies EU/UK regulatory requirements for international deployments.
- 2U EIA 19-Inch Rack Mount Chassis: Fits any standard 19-inch rack. The 3.25-inch height (2U) is efficient for dense racks — allow a half-U of clearance above and below for ventilation. At 16.15 lbs., it's manageable for a single technician to rack, though a second set of hands helps during wire termination.
Integration and Compatibility
The R2416CB220 is output-agnostic — any CCTV camera, PTZ, or accessory rated for 24VAC or 28VAC can draw from its outputs, regardless of manufacturer. It integrates naturally into rack-based NVR enclosures alongside recording hardware, keeping camera power and network infrastructure co-located. For large deployments, pair it with a structured power distribution plan that accounts for wire gauge, run length, and voltage drop on each camera circuit — AC power over long runs loses voltage, and 24VAC at the supply does not guarantee 24VAC at the camera head 300 feet away.
The modular EIA chassis and removable terminal blocks make it compatible with standard rack wiring practices. It does not provide battery backup — if UPS protection is required for camera power continuity during outages, plan a separate UPS upstream of the R2416CB220's input, or evaluate Altronix units with integrated battery management in the same product family.
Frequently Asked Questions
Q: Is the R2416CB220 NDAA Section 889 compliant?
A: Yes. The R2416CB220 carries verified NDAA compliance, along with TAA, BAA, and CE listings — making it eligible for federal, state, and GSA contract installations.
Q: Can the R2416CB220 run at both 24VAC and 28VAC at the same time?
A: No. The unit operates in one voltage mode at a time — either 24VAC at 8A (200VA total) or 28VAC at 7A (200VA total). All 16 outputs share the selected output voltage.
Q: What is the maximum load per output on the R2416CB220?
A: Each of the 16 PTC-protected outputs is rated at 2.5A maximum. At 24VAC the typical per-device allocation is 0.5A; at 28VAC it is 0.4375A per device, with the 2.5A per-port cap applying in both modes.
Q: Does the R2416CB220 fit a standard 19-inch rack?
A: Yes. The chassis is a modular 2U EIA 19-inch rack mount design, measuring 19.12 inches wide by 3.25 inches tall by 8.5 inches deep. Altronix recommends allowing a half-U of ventilation clearance above and below the unit.
Q: What is the warranty on the R2416CB220?
A: Altronix lists a Lifetime Warranty on the R2416CB220 per the manufacturer's product page.
Q: Does the R2416CB220 include battery backup?
A: No. The R2416CB220 is a straight AC distribution unit with no integrated battery or UPS functionality. If power continuity during outages is required, install a compatible UPS upstream of the unit's 220VAC input.
The R2416CB220 is one of the cleaner solutions I've seen for centralizing AC camera power in a 220VAC environment. The thing that stands out immediately is the 16 individually PTC-protected outputs — each auto-resetting, each with its own status LED. On a 16-camera install, that alone saves you an hour of diagnostics the first time a camera shorts. I've wired enough systems where one bad PTZ took out a whole power zone to appreciate what that per-port protection actually means in the field.
Technical Highlights:
- 200VA Total Output Capacity: Whether you're running 24VAC at 8A or 28VAC at 7A, the total available power is 200VA. Useful to know when you're mixing cameras (typically 0.5A each at 24VAC) and heated housings — you can load out 16 ports and still stay within budget if each device pulls at or below the 0.5A typical figure.
- Per-Output PTC Protection at 2.5A: Self-resetting fuses mean no service call to swap a blown fuse on a faulted circuit. The 2.5A per-port cap also gives you room for accessories that pull more than a standard camera — within limits. Exceeding 2.5A on any single output will trip the PTC; once the load is cleared, it resets automatically.
- NDAA + TAA + BAA + CE All Verified: Four agency listings on one SKU is unusual and valuable. For integrators bidding government or GSA-schedule work, the NDAA and TAA compliance documentation is often a contract requirement, not a preference. CE covers you for international deployment without sourcing a separate regional unit.
Deployment Considerations:
- The spec sheet calls for half-U of clearance above and below for ventilation — don't rack this unit flush against adjacent gear in a dense enclosure. At 90 BTU/hr heat output, airflow matters for long-term reliability.
- This unit has no battery backup. If your site requires camera uptime during power outages — hospitals, corrections, transit — put a UPS upstream of the 220VAC input. Don't assume the PTC protection covers anything other than output overcurrent; it won't help you during a mains failure.
This unit is the right call for international facilities, embassy and government builds, or any commercial site where 220VAC is the native distribution voltage and you need 16 cameras under one roof with per-circuit fault isolation and full compliance documentation in one box.
