Eaton offers a complete line of Type AP, MTE and MTK Industrial Control Transformers, which provide stepped-down voltages to machine tool control devices. Each unit must pass rigid tests for turns ratio, insulation, continuity, and over potential. Performance meets or exceeds ANSI/NEMA ST-1 requirements. With a 50-60 Hz operation standard, transformers are designed for loads requiring extremely good regulation. Regulation also exceeds ANSI/NEMA requirements.
