The MTE Series A Sine Wave Filters from Westek Electronics have been specifically formulated to eliminate problems of motor/cable insulation failures, heating, and audible noise, while reducing  electromagnetic interference (EMI) by cancelling the high dV/dt associated with inverter output waveforms.

These Sine Wave Filters provide a Sine Wave output voltage when driven from Variable Frequency Drives or other types of PWM inverters with switching frequencies from 2kHz to 8kHz.
The use of the MTE Sine Wave Filter enables protection against  long lead drive to motor excess voltage problems.

These filters meet the IEEE-519  requirements and permit the use of standard transformers.

For variable and constant torque applications,  it is recommended to  select filters based on the current rating of the motor. Filter current ratings have been designed to meet the NEC requirements. For applications that use motors with current ratings that exceed NEC values, it is recommended to select filters with a current rating equal to or greater than that of the load. Where a single filter feeds multiple motors it is best to select the filter based on the total motor current.
