Low-voltage transformers

Control power transformers

Eaton offers a complete line of Type AP, MTE and MTK control power transformers, which provide stepped-down voltages to machine tool control devices, enabling control circuits to be isolated from all power and lighting circuits. Control power transformers are a featured component in a control panel to run lower voltage equipment such as HVAC, assemblies and industrial machinery.
