Packard PF42440 Control Transformer 120/208-240V PRI 24V SEC 40VA

The Packard PF42440 Control Transformer is an electrical part that is used in HVAC systems. It is intended to reduces the 120/208-240V primary power to a 24V secondary outputs that is required by thermostats, relays and control boards. Magnetic induction between the primary and secondary windings is used in the transformers to ensure safe and stable control voltage. It is fitted in the equipment controls compartment and connected up to the high-voltage supply and the low-voltage control circuit. It is used to provide dependable control power, consistent signal operation.
