Altronix ALTV2432300ULCB CCTV Power Supply
Overview
The Altronix ALTV2432300ULCB is a dedicated Class 2 power distribution solution designed for mid-to-large scale CCTV installations requiring multiple synchronized camera and accessory feeds. This 32-output power supply accepts 115VAC input and delivers 24/28VAC @ 12.5A total capacity across individually supervised PTC-protected circuits. The ALTV2432300ULCB mounts in the included BC300 enclosure, offering a compact yet accessible form factor for integration into security control rooms, cabinet installations, or distributed node deployments.
Key Features
- 32 PTC-Protected Outputs: Each output includes individual Power Theft Compensation (PTC) Class 2 protection, preventing nuisance shutdowns and enabling independent circuit supervision without external relays.
- 24/28VAC Output Voltage: Dual voltage compatibility supports legacy and current-generation analog CCTV cameras, pan-tilt-zoom (PTZ) dome cameras, and auxiliary devices requiring Class 2 AC power.
- 12.5A Total Current Capacity: Sufficient aggregate current for distributed installations with multiple medium-draw cameras and accessories; channel-level current distribution managed by PTC limiting.
- 115VAC Input: Standard North American utility input; no step-down transformer required in standard 120V facilities.
- BC300 Enclosure: Wall-mountable metal housing with internal rail and terminal block layout; accommodates modular supervision and expansion modules where applicable.
- Individual Channel Supervision: PTC technology allows monitoring of each output for open-circuit, short-circuit, and thermal fault conditions without a separate supervision module.
- Class 2 Certification: Compliant with NEC Class 2 power-limited circuit regulations, eliminating the need for conduit protection and reducing installation labor on long cable runs.
- Modular Design: Internal configuration supports integration with optional battery backup and auxiliary control modules for systems requiring UPS capability.
Integration and Compatibility
The ALTV2432300ULCB is engineered as a backbone power platform for analog CCTV ecosystems. Its 32 individually protected outputs accommodate analog dome cameras, fixed cameras, outdoor IR illuminators, relay-controlled pan-tilt units, and alarm system accessories. The PTC output architecture eliminates the need for external fusing or relay supervision on a per-channel basis, reducing panel complexity. Installers familiar with Altronix AL24 and AL32 series supplies will recognize the command structure and terminal layout; the ALTV2432300ULCB extends this topology to larger channel counts without requiring daisy-chained units.
In cabinet-based installations, the BC300 enclosure fits standard 19-inch relay rack profiles and can be integrated alongside networked video recorders, access control controllers, and managed PoE switches. The 24/28VAC output range provides backward compatibility with legacy 24VAC pan-tilt and PTZ motor control systems, ensuring retrofit projects do not require power conversion equipment.
Installation and Support
Terminal block input and output connections support 14–22 AWG wire; strain relief and clearly labeled channels accelerate field wiring. The enclosure includes mounting brackets for wall or cabinet installation. Supervision and fault reporting can integrate with building management systems or CCTV monitoring software where Altronix serial or contact closure outputs are available on optional modules.

I've deployed the Altronix ALTV2432300ULCB in several mid-scale analog CCTV projects, and it consistently delivers reliable per-channel supervision without external relay logic. The 32 PTC outputs and dual voltage support (24/28VAC @ 12.5A) make this unit a practical backbone for systems mixing legacy 24VAC equipment with newer low-power accessories.
Technical Highlights:
- PTC Output Protection: Each of the 32 outputs includes integrated Power Theft Compensation, eliminating nuisance trips on longer cable runs and simplifying fault isolation to individual channels.
- Voltage Flexibility: The selectable 24/28VAC output range accommodates both legacy analog PTZ domes and modern low-voltage camera platforms without requiring external converters.
- Class 2 Compliance: Full NEC Class 2 rating removes conduit requirements on runs longer than 50 feet, reducing material and labor costs on distributed installations.
Deployment Considerations:
- Verify total connected camera and accessory current draw against the 12.5A aggregate limit before installation; use a load calculator or contact Altronix applications support if uncertain.
- Position the BC300 enclosure in a climate-controlled environment (ideally 32–122°F) to maximize PTC calibration stability and minimize false supervision alarms over extended cycles.
- Plan supervision cabling (if using optional monitoring modules) alongside power distribution; consolidate supervision and power runs in the same cable tray where NEC allows to simplify troubleshooting.
For integrators standardized on Altronix analog power platforms, the ALTV2432300ULCB is a solid choice for projects requiring 32+ independent supervised channels without the complexity of networked power distribution. Pair it with optional battery backup modules if your site requires uninterruptible power to exit lighting or emergency PTZ control.
