Description
The York S1-025-37431-003 Transformer is a high amperage electrical device that takes high voltage and steps it down to a safe and useful 24V output for use in HVAC control circuits. This transformer has an input voltage range of 460–575V and a frequency of 60Hz and was developed to serve large commercial HVAC systems that operate at high voltage. This voltage is then reduced to 24 V by the transformer, and this is a common voltage used to control thermostats, relays, and control boards, among other hot HVAC unit components. The efficiency of HVAC systems mainly relies on the reliable performance of this small transformer. It reduces maintenance costs and protects other control components that are sensitive to high voltage from damage.
