SineWave Guardian® and dV Sentry® Filters

High Frequency SineWave Guardian®

If you’re not leading, you’re following. Innovation is here.

At MTE, we have found a way to make our best-in-class  motor protection solution, the SineWave Guardian® Filter, even better. Featuring the same unequaled performance, the market leading High Frequency SineWave Guardian uses innovative technology to optimize protection for high frequency motors. Our new filter features reduced voltage drop and virtually eliminates voltage distortion (THVD) generated by Variable Frequency Drives (VFDs). This results in reduced losses, protection against overheating motors, and ultimately providing less downtime. It can protect motors in some of the harshest conditions, with unmatched reliability and durability. The High Frequency SineWave Guardian Filter is the optimized motor protection solution for high frequency motors, exclusively by MTE.
