Product Details

Description

This heavy-duty step-down control transformer is a vital component for industrial and commercial HVAC systems, designed to safely convert 480V high-voltage input into a stable 24V low-voltage output. With a robust 100VA capacity, it provides the reliable power necessary for essential control circuits, including thermostats, relays, and contactors. Ideal for repairing non-functional heating and cooling units, this transformer ensures consistent electrical performance and long-term system safety. Built for durability in demanding environments, it is a preferred choice for technicians seeking a high-quality replacement to restore control board functionality and equipment communication in large-scale climate control systems.
