KMG with PQconnect sine wave filter converts the PWM wave form to a near sinusoidal wave form by eliminating the carrier frequency. PQconnect connectivity detects thermal switch alerts, monitors the filter performance, and verifies voltage distortion is at a recommended level.
TCI’s MotorShield (MSD) sine wave filters are used on the output of a VFD/drive to filter the PWM carrier frequency converting it into a clean voltage waveform. The MSD is suitable for carrier frequencies from 2 – 16 kHz. The MotorShield sine wave filter offers an added level of protection to your motor with minimal voltage drop.
V1K dV/dt filter
Output Line Reactors
V1K dV/dt filter provides motor protection by limiting voltage spikes to below 1,000 V for applications with leads lengths greater than 100 ft. 1 The V1K filter greatly extends the life of the motor and cable.
KDR line reactors are electrical components that help to protect 6-pulse rectifiers and power conversion devices such as variable frequency drives (VFDs). When used in conjunction with a VFD, a KDR line reactor can help reduce harmonics and protect the drive from harmful voltage spikes.
