Emerson conditions-White Rodgers 90-118E Fan Control Center Transformer W/Relay

The Emerson conditions-White Rodgers 90-118E Fan Control Center Transformer with Relay is used in HVAC systems. It controls the operation of the fan in the HVAC unit as a central control unit for this component. It operates by converting the main voltage to a lower voltage suitable for use in the fan motor and other low-voltage. The integrated relay controls the on and off of the fan depending on signals from the thermostat or other control parts. Advantages include efficiency being achieved since the fans will always function as required, temperature regulation is enhanced by the cycling of the fan and reliability is achieved by the design of the transformer/relay.
