Single Phase Control Transformers

Controlled Magnetics provides isolated, low and safe control voltage to logic and control circuits for electrical and power electronics equipment in industrial applications. Choose from our standard control transformer offerings or have us custom design and manufacture a transformer to your exact specifications. Control transformers allow stepped down voltages to machine tool control devices enabling control circuits to be isolated from all power and lighting circuits. Then grounded or ungrounded circuits that are independent of the power or lighting grounds can be used. Operator safety is greatly enhanced. Control circuits often contain switches, relays, contactors, solenoids, small motors, motor controls, motor starters, and other electromagnetic devices.
