Description
The Trane TRR02728 Transformer is a control power transformer designed to step down 115V primary input to a 24V secondary output with a 35VA rating for low-voltage control circuits. It is commonly used in furnace and air handling control panels, where it supplies stable power to thermostats, relays, and electronic controls. In HVAC systems, it supports safe and consistent voltage conversion for control operations. The unit is built for integration into electrical enclosures requiring compact step-down power supply for system operation and control logic.
