Description
The Trane TRR00548 Transformer 208/230V 50VA is designed to convert high-voltage input power to control power for low-voltage circuit operation in HVAC systems. It is placed in air handlers and rooftop equipment, where it supplies power to the relays, contactors, and control boards. It operates as a necessary electrical interface between the main power supply and the control circuit, ensuring stable low-voltage operation during heating and cooling cycles. It is used to restore proper control system operation in the equipment.
