Warner-branded power transformers are typically used in industrial and commercial applications such as machine tools, control panels, lighting systems, HVAC equipment, and distribution panels. They provide isolation and step-down for control circuits or local loads, often designed to meet UL/CE requirements. Typical uses include supplying 24-120 V control voltages from higher distribution levels, feeding contactors, relays, PLC I/O, and auxiliary equipment in factories, warehouses, and building services installations.
