Description
The Trane TRR03137 Transformer convert 115/120V incoming power to a 24V output for low voltage control circuits. Its 40VA rating identifies the available power capacity for connected controls while the primary and secondary windings provide the essential voltage conversion. Installed inside compatible air handlers, rooftop units, and furnaces, the transformer supplies thermostats, relays, contactors and other control components. This type of transformer provides the lower voltage required by their control circuitry in HVAC systems. Its electrical conversion allows the connected controls to operate from the higher incoming supply while maintaining the specified control output.
