KMG – Sine Wave Filter

Sine Wave Filter with Connectivity

The KMG with PQconnect provides connectivity into your sine wave filter. TCI’s sine wave filter converts the PWM wave form to a near sinusoidal wave form by attenuating the carrier frequency, allowing sensitive applications to take advantage of the efficiencies and savings that PWM output power supplies and VFDs can offer.Without the protection of a sine wave filter, premature equipment failure is caused by the VFD PWM carrier frequency and/or the high dV/dt voltage spikes at the motor terminals.Using the KMG with PQconnect technology ensures all the high value electrical pumping assets are being protected from failure. The KMG with PQconnect enables pumping and VFD process control adjustments to optimize uptime and prevent power quality issues. Real-time power quality data can be used to monitor and trend for early detection of abnormal conditions.
