Description
The Utica-Dunkirk 550001339 Transformer steps down incoming 120-volt line voltage to a 24-volt secondary output, supplying the low-voltage power required to operate thermostats, control boards, and safety circuits within the unit. It operates through electromagnetic induction between primary and secondary windings, converting line voltage at the primary side to a stable 24-volt AC output at the secondary side with a capacity of 40 volt-amperes to support connected control loads. Wired into gas-fired boilers and hydronic heating units within HVAC systems, stable voltage output through this transformer ensures consistent control circuit power and protects sensitive boards from line voltage variations.
