This heavy-duty step-down control transformer is engineered to convert high-voltage industrial power from 450V or 575V down to a stable 120V output. Essential for commercial HVAC and industrial machinery, it provides the necessary power to operate control circuits, relays, and onboard electronics. If your heating or cooling system's control board is not receiving power or experiencing intermittent electrical issues, this replacement transformer is a critical component for restoring safe and efficient operation. Built to withstand demanding environments, it ensures a consistent voltage supply for high-capacity ventilation and climate control equipment.
Type: Step-Down Control Transformer
Size: Standard Industrial
Application: Used in commercial air handlers, industrial HVAC systems, rooftop cooling units, and high-voltage electrical control panels to power 120V relays and auxiliary components.
Specifications: Primary Input Voltage: 450/575V AC; Secondary Output Voltage: 120V AC; Phase: Single Phase; Application: Electrical control circuit power supply.
