Offering reliability and durability up to 15,000 ft as protective filter in commercial and industrial applications, 380–480 V High Frequency SineWave Guardian™ cleans PWM waveforms generated by VFDs at switching frequencies from 4.8–8 kHz. Solution virtually eliminates voltage distortion (THVD) generated by VFDs, which results in loss reduction, protection against motor overheating, and minimized downtime. Footprint and modular design facilitate integration/installation.
