Frequency Conversion Systems engineered for harsh environments.

TEMCo Rotary Frequency Conversion Systems are used for converting from available supply power to 50Hz, 60Hz, or 400Hz. Typical applications include production line machinery, marine power, mining equipment, and export product testing.

Small footprint. Industrial Frequency Conversion Units employ a vertical chassis design to save significant floor space. Lowest cost per kW of solutions offered.


Precision Frequency Conversion System for grid power.

For laboratory equipment, the microchip industry, and sensitive medical equipment requiring tight frequency regulation.

Precision Frequency Conversion units maintain constant output voltage and frequency independent of supply line fluctuations.
