Sine wave filter,dv/dt filter, Rated Current 29A ,New design

SWF Series Sine Wave Filters convert the PWM output signal of motor drives into a smooth sine wave with low residual;
Reduce the resonance phenomenon caused by distributed capacitance and inductance of the long cable(longer than 50 meters);
Eliminate the excessive motor voltage caused by high dv/dt,
Reduce noise of motor by filter application;
Prolong motor life;
Protecting the motor insulation;
Increase transmission distance;
With the application of this filter, normal motor can replace variable frequency motor.

Applications:
Ventilators,conveyors,Pumps
HVAC installations, Compressors
Elevators ,Cranes , wind power,UPS,EPS
Motor drive with long cable
Motor drive with multiple motors in parallel
Medium voltage applications(deployed in front of the step-up transformer)

Characteristic:
Sikes Sine wave filters for various servo motor of VSD systems(esp for inverters or switching power suppliers),are designed to change the PWM output voltage of the inverter and generate an almost sinusoidal voltage . The passive series is intended for use in 380v-480v network.
Sikes offers you another economic choice except Schaffner and MTE filter .
