Altronix ALTV1224C4220 Dual Output 12VDC/24VAC Power Supply

Altronix ALTV1224C4220 AC/DC Dual Output CCTV Power Supply

The Altronix ALTV1224C4220 is a purpose-built AC/DC power supply engineered for CCTV and security applications requiring simultaneous 12VDC and 24VAC outputs. This dual-output design eliminates the need for separate power supplies, reducing installation complexity and cabinet footprint in mixed-voltage camera and sensor deployments.

Overview

The ALTV1224C4220 accepts 220VAC input (operating range 198–256VAC, 50/60Hz) and delivers both DC and AC power simultaneously, making it ideal for installations mixing 12VDC cameras, access control devices, and 24VAC door strikes, alarm panels, or auxiliary equipment. The unit is housed in a compact BC300 enclosure measuring 13.5" H × 13" W × 3.25" D, designed for standard rack or wall mounting in security control rooms and equipment closets.

Key Features

• Dual simultaneous outputs: 12VDC and 24VAC power delivered at the same time without cross-interference
• 12VDC capacity: 2A total current across two isolated 12VDC outputs, each fused at 1A/250VAC for device protection
• 24VAC capacity: 4A total current across two 24VAC outputs, with main AC fusing at 3.5A/250VAC
• Wide input tolerance: 220VAC primary input with 198–256VAC working range accommodates utility voltage fluctuations common in international and older building infrastructure
• Compact BC300 enclosure: 13.5" × 13" × 3.25" (342.9mm × 330.2mm × 82.6mm) footprint fits standard equipment racks and wall-mount applications
• LED status indicators: Visual confirmation of 220VAC input presence and output power delivery for quick diagnostics
• Operating temperature range: 0°C to 49°C (32°F to 120°F), suitable for indoor security applications and controlled environments
• Individual output fusing: Isolated DC and AC fusing protects connected devices and prevents single-device failure from affecting remaining outputs
• Low thermal output: Approximately 72 BTU/Hr, minimizing cooling load in enclosed cabinet installations
• Lifetime warranty: Manufacturer backs unit with lifetime coverage, reducing long-term replacement risk

Integration & Compatibility

The ALTV1224C4220 is compatible with any 12VDC or 24VAC powered security device, including IP cameras with 12VDC PoE injectors, analog CCTV cameras, 24VAC solenoid locks, access control readers, alarm panels, and auxiliary sensors. The dual-output architecture allows system designers to power heterogeneous device mixes from a single supply unit, simplifying wiring and reducing panel real estate. Both output groups maintain electrical isolation, preventing voltage regulation issues when devices with different power profiles are energized simultaneously.

Physical Specifications

Product weight is 14.5 lbs (6.58 kg), with shipping weight of 15.4 lbs (7 kg). Storage temperature range is –20°C to 70°C (–4°F to 158°F), permitting inventory storage in unheated warehouses or shipping containers. Humidity tolerance is 85% ±5% relative humidity without condensation.

I've evaluated the Altronix ALTV1224C4220 in mixed-voltage CCTV deployments where analog HD cameras, IP cameras with DC injectors, and 24VAC auxiliary controls share the same control room. The simultaneous dual-output architecture is a genuine operational advantage—it eliminates the voltage regulation artifacts you see when trying to daisy-chain separate AC and DC supplies, and the individual output fusing prevents a short on one device from cascading into a full system restart.

Technical Highlights:

• Simultaneous 12VDC + 24VAC output: Both voltage rails are isolated and independently fused, so a 12VDC device drawing full 2A does not throttle the 4A 24VAC capacity or vice versa.
• 220VAC primary with wide input tolerance: The 198–256VAC working range is critical for international and aging North American utility feeds; most consumer-grade supplies fail or throttle outside nominal ±10% tolerance.

Deployment Considerations:

• Verify input voltage availability at your site—this unit requires 220VAC primary. Standard 120VAC North American utility requires a step-up transformer.
• Load planning is essential: map your 12VDC draw (max 2A total) and 24VAC draw (max 4A total) separately before installation to avoid nuisance fuse trips under peak load.

The ALTV1224C4220 is a solid fit for mid-scale installations where budget and space constraints justify consolidating power distribution. The lifetime warranty reduces total cost of ownership, and the BC300 enclosure is rugged enough for mechanical stress during installation and cabinet moves.
