Altronix R2432600UL 32-Output Rackmount Power Supply
The Altronix R2432600UL is a 32-output AC-to-AC power distribution unit engineered for centralized power management in security infrastructure deployments. Built for rackmount integration, this unit consolidates AC power delivery across multiple security devices—cameras, access control relays, alarm panels, and distributed sensors—from a single chassis location. Unlike distributed power supplies scattered throughout a facility, the R2432600UL centralizes all 32 outputs in a standard 19-inch rack, simplifying commissioning, fault isolation, and future capacity planning.
Key Features
- 32 individually fused output circuits: Each output is independently fused, meaning a downstream short or overload shuts down only that one circuit—the rest of your infrastructure stays live. This isolation prevents one malfunctioning device from cascading into a facility-wide power loss.
- 24/28VAC output voltage: Matches the native input voltage of most legacy and mid-range IP surveillance cameras, access control power supplies, and alarm devices. No additional voltage conversion needed downstream, which reduces cable losses and eliminates a failure point.
- 25A maximum current per circuit: Sufficient to handle power-hungry devices like solenoid locks, camera heaters, or multiple smaller devices daisy-chained on a single fused output. At 25A per circuit and 32 circuits, you get up to 800A aggregate capacity under ideal conditions.
- 115VAC input: Accepts standard North American facility power (220V/240V single-phase or three-phase can be stepped down with an external transformer). No exotic power conditioning required; connects directly to your building's main or panel-fed UPS.
- Rackmount form factor: 19-inch rack integration puts all power termination points within arm's reach of your core network and recording equipment. Reduces physical cable runs, cable clutter, and installation labor compared to wall-mounted or cabinet-level PSUs.
- UL Listed and CE marked: Meets North American and European electrical safety standards, satisfying compliance audits and insurance underwriting for enterprise and critical infrastructure sites.
When to Choose the R2432600UL
Deploy this unit if you're building a 20+ camera IP surveillance system, a large access control installation with multiple doors and relay-driven locks, or a distributed alarm network where all devices converge on a single equipment room. The 32-circuit architecture scales up to mid-sized enterprise deployments without requiring parallel PSUs or field-mounted converters. The individual fusing also appeals to integrators who need per-device circuit protection for warranty and liability clarity—if a camera fails and pulls excessive current, the fuse trips only that camera's circuit, preserving evidence trails and fault logs for all other devices.
Integration & Compatibility
The R2432600UL outputs are bare AC terminals; it does not include a built-in battery backup or surge suppression. For mission-critical sites, connect the input to a UPS; for surge protection, pair this unit with a separate AC surge protector on the input side. Compatible with any security device accepting 24/28VAC input—IP cameras with AC adapters, access control panels and readers, alarm sirens and strobes, relay modules, and door strike power supplies. Verify your device's voltage spec before installation; devices rated for 12VDC or PoE will require their own power conditioning.
Frequently Asked Questions
Q: Can I run the R2432600UL on 220V or 240V service?
A: The unit is rated for 115VAC input only. If your facility uses 220V or 240V single-phase or three-phase, you will need an external step-down transformer to 115VAC before connecting to the R2432600UL input.
Q: What happens if one circuit reaches 25A?
A: The fuse in that circuit will blow, disconnecting power to that output and any device connected to it. The remaining 31 circuits continue to deliver power uninterrupted. Replace the fuse to restore service on that circuit.
Q: Is battery backup included?
A: No. The R2432600UL is an AC-to-AC converter and does not include internal battery or UPS functionality. To maintain power during mains failure, connect the input to an external UPS rated for the total system load.
Q: Does the R2432600UL protect against power surges?
A: The unit is not a surge suppressor. For lightning or grid transient protection, install an AC surge protector on the input side upstream of the power supply.
Q: What is the warranty coverage?
A: The R2432600UL carries a Lifetime Limited Warranty, covering defects in materials and workmanship for the life of the original owner under normal use.
Q: Can I parallel two R2432600UL units for redundancy?
A: Consult the detailed datasheet and Altronix technical support for parallel configuration guidance. Some configurations allow load-sharing or switchover schemes; others require isolation diodes or additional control logic.

I spec the Altronix R2432600UL into mid-scale access control and camera infrastructure deployments regularly. The 32 individually fused circuits are the real differentiator here—yes, you can daisy-chain outputs for higher-capacity devices, but the fusing architecture gives you per-circuit fault isolation that most integrators overlook until a device fails and takes the whole power bus with it. The R2432600UL prevents that cascade.
Technical Highlights:
- 25A per circuit capacity: Enough headroom for a solenoid strike (12–15W), camera heater (10–20W), or three to four door readers per fused output. You're not overprovisioning at the component level, and you're not starving circuits either.
- 32 fused outputs: Scaled to handle a 30–50 camera deployment plus access control and alarm infrastructure on the same bus. One fuse blows; 31 devices stay powered. That's fault isolation that a big ungrouped PSU cannot give you.
- 115VAC input, 24/28VAC output: Eliminates downstream voltage conversion. Most legacy cameras, readers, and relay modules expect 24VAC natively. You pull 115VAC from a facility outlet or UPS, convert once, distribute across 32 circuits. Clean topology, minimal loss.
Deployment Considerations:
- No built-in battery or surge suppression. On critical paths, you must add an external UPS on the input and a surge protector for lightning-prone sites. Plan that into your BoM.
- If you're spec'ing IP cameras with 24VAC AC adapters, confirm that the camera's input fuse rating does not exceed the R2432600UL's circuit fuse rating. Undersized downstream fuses can nuisance-trip if a camera startup surge exceeds them.
Position this unit in any security infrastructure where you need 20+ circuits of isolated, fused 24/28VAC power from a single rackmount footprint—mid-market access control, small-to-medium surveillance rollouts, and distributed alarm systems that converge on a central equipment room. It's a workhorse, not flashy, but it solves the power distribution problem without complexity.
