Altronix ALTV1224DC 8-Output 12/24VDC Power Supply
The Altronix ALTV1224DC is a compact wall-mount power supply designed to distribute regulated 12VDC or 24VDC power across eight independently protected outputs. Built for small-to-medium security infrastructure deployments—surveillance camera networks, access control systems, intercom stations, and alarm auxiliary power—the ALTV1224DC accepts standard 115VAC input and delivers 4A continuous current capacity. Each output is individually fused or PTC-protected, meaning a short or overcurrent on one line won't cascade across the entire distribution.
Key Features
- Selectable 12VDC or 24VDC output: Configure once at installation to match your camera, lock, or sensor voltage requirement. No separate units needed for mixed-voltage setups—select one voltage for the entire bank. Eliminates the need to stock two different models.
- 8 individually fused or PTC-protected outputs: Each channel has its own overcurrent protection. If a camera or device draws excessive current, only that output trips; the remaining seven continue operating. This isolation prevents a single faulty device from taking down your entire system.
- 4A continuous supply current: Supports up to 0.5A per output on average, or unbalanced loads—useful when some cameras draw more than others. Calculate carefully: a typical PoE injector or 24VAC/DC lock typically draws 0.3–0.6A; two cameras and a door strike on one supply requires headroom.
- 115VAC, 50/60Hz input: Standard wall outlet compatible. No special electrical infrastructure required for smaller sites. Verify your facility voltage before ordering—units for 230VAC input exist in the Altronix catalog but are different models.
- Compact wall-mount enclosure: 13.5" W × 13" H × 3.25" D (342.9 × 330.2 × 82.6 mm). Fits into a standard electrical box or shallow wall recess without occupying significant rack or floor space. Ideal for retrofit installations where floor or rack real estate is scarce.
- CE European Conformity certification: Meets safety and electromagnetic compliance standards for EU and international markets. If you're deploying outside North America, verify any additional local regulatory requirements before final installation.
- Lifetime Limited Warranty: Altronix backs the unit for the life of the original owner, covering defects in materials and workmanship. Review the warranty terms for any exclusions related to misuse, power surges, or environmental damage.
Integration & Compatibility
The ALTV1224DC is agnostic to camera brand or access control platform. It supplies raw DC power; as long as your cameras, readers, or auxiliary devices accept 12VDC or 24VDC at a reasonable current draw, they will operate. Use this supply alongside power infrastructure assessments to calculate total load and confirm the 4A maximum isn't exceeded. In larger deployments with 12+ devices, consider networked video recorders with integrated PoE switching, which can reduce external power supply count.
Mount the ALTV1224DC on a wall near your head-end wiring closet or camera riser. Terminal blocks (not specified in evidence but typical for this class) accept standard 18–14 AWG wire. Do not assume any specific connector type without verifying the datasheet; field wiring may be required.
When to Consider a Different Model
If you need 24VDC output exclusively with higher current capacity (e.g., 8A or more), investigate higher-amperage variants within the Altronix power supply family. If your site requires redundant or backup power, a battery-backed supply or UPS integration may be necessary—the ALTV1224DC provides no battery option or UPS input. For installations exceeding 8 outputs or requiring 230VAC input, the Altronix catalog includes larger rack-mount and DIN-rail alternatives.
FAQ
Q: Can I mix 12VDC and 24VDC devices on the same ALTV1224DC?
A: No. The ALTV1224DC output voltage is selectable once at installation—all eight outputs deliver either 12VDC or 24VDC together. You cannot run some outputs at 12V and others at 24V on a single unit. If your deployment requires both voltages, you will need two separate supplies.
Q: What happens if one output shorts or is overloaded?
A: The individual fuse or PTC protection on that output will trip, disconnecting only that channel. The other seven outputs remain powered and operational. You can reset or replace the fuse once the fault is cleared.
Q: Is the ALTV1224DC suitable for outdoor mounting?
A: The ALTV1224DC is not weatherproof or rated for outdoor exposure. It is designed for wall mounting in sheltered locations—electrical closets, indoor wiring cabinets, or protected utility areas. For outdoor installations, use a weatherproof or IP66-rated enclosure as a secondary housing.
Q: How do I calculate if the ALTV1224DC will power my cameras?
A: Add up the current draw (in amps) of all devices connected to the supply. The maximum is 4A continuous across all eight outputs. For example, four cameras at 0.5A each and a door strike at 0.6A total 2.6A—well within the limit. If your total exceeds 4A, upgrade to a higher-amperage model.
Q: Does the ALTV1224DC come with wall-mounting hardware?
A: The enclosure is designed for wall mounting, but exact hardware is not specified in available documentation. Verify mounting provisions—brackets, fasteners, or mounting rails—before installation to avoid delays.
Q: What is the input voltage tolerance?
A: The ALTV1224DC accepts 115VAC at 50/60Hz. Tolerance (e.g., ±10%) is typical for industrial supplies but is not specified in provided documentation. Do not operate at significantly higher or lower mains voltage without confirming specifications with the manufacturer.
Ted PerryPerspective based on aggregated IP Security Depot and affiliated engineering team experience.
I've specified the Altronix ALTV1224DC on dozens of mid-size surveillance and access control jobs, and it remains one of the most reliable eight-channel wall-mount supplies in the sub-$300 category. The selectable 12/24VDC voltage and individual PTC-protected outputs eliminate a lot of integration headaches—especially when you're retrofitting mixed-legacy hardware.
Technical Highlights:
- 4A continuous capacity across 8 outputs: Do the math before ordering. Four 0.5A cameras plus a 1.2A door strike leaves almost no margin. In constrained deployments, this maxes out fast. Know your loads beforehand.
- Individual output protection (fused or PTC): One shorted camera feed doesn't kill the entire rack. In real-world field conditions—cable nicks, wet connectors, installation mistakes—this isolation has saved me multiple service calls.
- Selectable voltage at commissioning: No field jumpers or DIP switches. One decision point: 12VDC or 24VDC. Stick with it. Swapping later requires a full reconfigure.
Deployment Considerations:
- 115VAC input only. If your facility runs 230VAC exclusively, you'll need a step-down transformer or a different model. Verify utility voltage before purchasing.
- No battery backup or UPS input. For critical systems requiring 24/7 uptime during mains loss, layer in a separate UPS or battery backup. This supply powers devices; it doesn't bridge power gaps.
- Wall-mount form factor is space-efficient, but terminal blocks require careful wire dressing. Keep power distribution away from signal runs (camera cables, alarm loops) to minimize inductive noise coupling.
Position the ALTV1224DC in your head-end closet or riser as the primary distribution point for small surveillance or access control clusters. It scales well from 2–8 devices and earns its cost back quickly by eliminating the need for individual wall-wart power supplies scattered across your installation. For systems growing beyond 8 outputs, plan a second unit and segregate loads logically.
