A 480V to 120V control transformer<\/strong><\/a> is widely used in industrial control panels, machine tools, CNC equipment, motor control centers, automation systems and manufacturing machinery where the main power supply is 480V AC but control components require a lower 120V AC voltage.<\/p>\n

The transformer steps down the incoming 480V supply to 120V for control circuits while providing a dedicated power source for devices such as contactors, relays, PLC-related equipment, solenoid valves, pilot lights, timers and operator controls.<\/p>\n

For industrial equipment manufacturers and electrical contractors, selecting a 480V to 120V control transformer involves more than matching the input and output voltage. VA capacity, inrush current, frequency, phase, insulation, terminals, mounting, enclosure and operating environment<\/strong> all affect transformer performance.<\/p>\n

This guide explains the main specifications, sizing considerations and applications of 480V to 120V control transformers and provides practical guidance for selecting a customized industrial control transformer.<\/p>\n
