Series A Sine-Wave Filters provide a 5% THVD sine-wave output voltage for motor and cable protection when driven from PWM inverters with 2-8 K Hertz switching frequencies. These filters eliminate the problem of motor / cable insulation failures plus reduce electro-magnetic interference (EMI/RFI) by eliminating the high dV/dT from long-lead runs where the distance between the motor and the inverter is up to 15,000 feet. In addition, MTE Series A Sine Wave Filters eliminate motor audible noise and heat attributed to control by PWM inverter drives. Without a Sine-Wave filter VFD long-lead cable voltages will exceed 900 volts RMS.
