Altronix ALTV248 8-Output 24/28VAC Power Supply
Overview
The Altronix ALTV248 is a wall-mounted AC power supply engineered for multi-camera CCTV deployments where distributed 24/28VAC power is required. Its eight independent fused outputs allow you to power multiple cameras and accessories from a single central unit, eliminating the need for separate power supplies at each device location. This architecture reduces installation labor and simplifies circuit protection across your surveillance network.
Key Features
- Eight fused outputs: Each output is independently protected, so a short or overload on one camera circuit does not affect the others—a critical feature in multi-camera systems where downtime of even one feed impacts your monitoring posture.
- 24/28VAC output voltage: Supports standard CCTV-grade pan-tilt-zoom (PTZ) cameras, lens motors, and analog accessories that operate on AC power—common in older infrastructure and many commercial systems still in service.
- Wall-mount form factor: Compact mounting lets you install the unit in control rooms, server closets, or equipment racks without consuming floor space; a practical consideration in dense urban facilities or retrofit projects where real estate is limited.
- AC input architecture: Accepts standard facility AC power (110–240V), eliminating the need for external power conversion or dedicated battery backup systems unless your design requires it.
- Lifetime Limited Warranty: Manufacturer-backed coverage reflects confidence in component reliability and simplifies long-term asset management for integrators planning multi-year deployments.
Deployment Considerations
The ALTV248 is purpose-built for analog and legacy AC-powered CCTV ecosystems. It is not suitable for PoE (Power over Ethernet) cameras or modern IP surveillance systems that rely on DC power distribution. If you are designing a new installation with IP cameras, evaluate network video recorders and IP cameras that simplify power delivery via standard network infrastructure.
For facilities running a hybrid model—combining legacy PTZ and dome cameras with newer IP gear—the ALTV248 serves as the AC backbone while managed power supplies handle PoE or DC distribution in parallel. Load-balance across the eight outputs during installation to avoid nuisance fuse trips on heavily taxed circuits.
When to Choose a Different Model
If your camera system uses PoE or requires 12VDC power, this AC-only supply is the wrong fit. Consider a PoE+ managed switch or a dedicated DC power infrastructure instead. Likewise, if you need redundant power paths or uninterruptible operation during facility AC loss, pair the ALTV248 with a UPS or evaluate higher-capacity Altronix power products designed for critical surveillance environments.
Integration Scope
Installation is straightforward: mount the unit to a wall or DIN rail, run your facility AC input (110–240V), and wire camera and accessory loads to the fused outputs. Each fuse is clearly labeled, making troubleshooting and maintenance predictable. No software configuration, no network integration, no firmware updates—pure passive power distribution.
Frequently Asked Questions
Q: What amperage does each output on the ALTV248 support?
A: Refer to the ALTV248 datasheet for specific fuse ratings and per-output current limits. Contact the manufacturer or your systems integrator to confirm load matching before final installation.
Q: Can I connect IP cameras directly to the ALTV248?
A: No. IP cameras require PoE or DC power via their network ports or barrel connectors. The ALTV248 outputs 24/28VAC, which is designed for legacy CCTV cameras, PTZ motors, and AC-rated accessories only.
Q: Is the ALTV248 suitable for outdoor installations?
A: The ALTV248 is a wall-mount indoor unit. It is not rated for direct weather exposure. Install it in a protected enclosure, closet, or equipment room, and run outdoor camera power feeds through conduit or shielded cabling to maintain signal integrity and safety.
Q: What happens if one fuse blows on the ALTV248?
A: Only the fused circuit affected by the overload shuts down; the other seven outputs remain operational. This isolation prevents a single camera short from cascading failure across your entire surveillance feed.
Q: Does the ALTV248 come with spare fuses?
A: Verify package contents in the product documentation or contact your supplier. Standard practice is to keep common fuse ratings on hand for field service.
Ted PerryPerspective based on aggregated IP Security Depot and affiliated engineering team experience.
The Altronix ALTV248 is a no-frills passive power distribution tool that works best in mature CCTV environments still reliant on 24VAC equipment. I specify it frequently for retrofit projects where analog dome cameras and PTZ motors are already in place—the eight fused outputs eliminate the clutter of multiple wall-wart supplies and give you centralized circuit protection out of the box.
Technical Highlights:
- Eight independently fused outputs: Each circuit breaker is isolated, so a camera motor stall or wiring fault on one line doesn't collapse the power rail for the other seven devices. That redundancy matters in retail or banking deployments where you cannot afford monitoring gaps.
- 24/28VAC output: Matches the power appetite of the vast majority of legacy PTZ cameras, analog dome housings, and lens actuators still deployed in commercial facilities. No impedance mismatch, no voltage regulation headaches—plug and wire.
- Wall-mount industrial form factor: Compact enough to fit in a 19-inch rack or tuck into a control-room corner, yet robust enough to handle years of continuous duty without active cooling or environmental compensation.
Deployment Considerations:
- The ALTV248 is purely AC-powered—do not spec this unit if your facility lacks stable 110–240V AC supply or if you are building a PoE or DC-dominant infrastructure. Mixing power domains adds complexity without gain.
- Fuse replacement is straightforward, but stock spares on-site. A blown fuse during weekend business hours with no backup supply on hand is a support call you want to avoid.
Best deployment scenario: legacy analog CCTV systems in older commercial buildings—warehouses, older retail chains, industrial facilities—where rip-and-replace with IP cameras is not yet budgeted. The ALTV248 extends the life of that infrastructure cleanly and affordably.
