This heavy-duty 75VA control transformer is a critical electrical component designed for HVAC systems and commercial appliance applications. It efficiently steps down a 277V primary input to a standard 24V secondary output, providing the necessary low-voltage power to operate thermostats, gas valves, relays, and electronic control boards. With a 75VA power rating, it is built to handle the demands of commercial air handlers, unit ventilators, and industrial heating and cooling equipment. This transformer is an essential replacement part for restoring functionality to climate control systems where precise voltage regulation is required for safety and performance.
