Slant Fin 461-024-000 Transformer 120V Primary 24V Secondary 27/3VA

The Slant Fin 461-024-000 Transformer 27/3 VAC is a power controlling component used to convert 120V primary power to a 24V secondary supply for low-voltage circuits in HVAC systems. It supports operation of thermostats, relays, and ignition or control boards in furnaces, boilers, and air handling equipment in commercial connections. The transformer provides electrical isolation and stable reduced voltage for control circuits, ensuring consistent signaling within HVAC system operation. It is installed in units where stepping down line voltage is required for safe control circuit distribution.
