Utica-Dunkirk 240007897 Transformer 3VA 120V PRI/24V SEC 47A

The Utica-Dunkirk 240007897 Transformer is a dependable electrical part that is used to transform voltage from 120V primary to 24V secondary with 47A and 3VA power output. It operates in the way that it transforms high primary voltage to a safe and useful secondary voltage for HVAC systems. The working process is based on electromagnetic induction which decreases voltage to the level that is appropriate for the control of heating and cooling. This transformer is used to improve the efficiency of the system by supplying the required low voltage for the operation of relays and thermostats and is used in increasing the longevity of HVAC systems.
