The Altronix ALTV248UL is a versatile AC power supply and charging unit designed for low-voltage security and surveillance system applications, configured in a compact wall-mount enclosure. Its primary function is to convert standard 120VAC line voltage into regulated 24VAC output, providing reliable power for a variety of devices commonly used in electronic security installations. This unit is particularly suited for powering pan-tilt-zoom (PTZ) camera mechanisms, video doorbell systems, and other equipment requiring a stable 24-volt alternating current supply. The integrated design includes a built-in battery charging circuit with connections for a sealed lead-acid (SLA) backup battery, ensuring continuous system operation during temporary AC power failures.

Constructed in a durable, surface-mountable metal or high-impact plastic enclosure, the ALTV248UL is engineered for easy installation in electrical closets, utility rooms, or directly adjacent to the equipment it serves. The unit typically features screw terminal blocks for secure and straightforward wiring connections for the AC input, DC output, and battery terminals, complying with standard installation practices. It incorporates protective features such as a resettable thermal circuit breaker and electronic protection against overloads, short circuits, and reverse polarity, safeguarding both the power supply and the connected devices.

Listed to UL standards for safety, this power supply is designed for reliability in continuous 24/7 operation. Its efficient transformer-based or switching design minimizes energy loss and heat generation. By consolidating power conversion and backup battery support into a single, ruggedized wall-mount package, the ALTV248UL provides a tidy and dependable power solution for integrators, simplifying the power infrastructure for access control, intercom, and video surveillance systems.
