Description
The First Company E1372 Transformer 208-240-PRI 24V-SEC is an electrical control component used to step down line voltage to a lower control voltage operation. It operates through electromagnetic induction, where a primary winding receives and transfers energy to a secondary winding that outputs for regulating circuits. It is commonly installed in air handlers, fan coil units, and heating or cooling control panels during system wiring or replacement servicing. It operates as a power supply element for thermostats, relays, and control boards, ensuring stable low-voltage operation and regulating signal distribution in HVAC systems.
