Lochinvar & A.O. Smith 100170159 Transformer 40VA 120Vpri24Sec

The Lochinvar & A.O. Smith 100170159 Transformer is an important part of HVAC systems which serves to step the voltage in the AC circuit down from 120 Volts to 24. This voltage decrease is necessary to supply a large number of low-voltage devices in the HVAC system, such as control boards, relays, and sensors. A transformer is based on the electromagnetic induction concept the first coil is provided with a greater voltage supply and the second coil provides a smaller voltage output. It facilitates efficient control of power distribution, provides shielding from voltage variations, and enhances dependability.
