MTE Expands the SineWave Guardian™ Product Family with High Frequency SineWave Filters

Posted

MTE’s new High Frequency SineWave GuardianTM is specifically designed to protect high frequency motors against overheating and premature failures, resulting in less downtime

Menomonee Falls, WIApril 1st, 2015 –MTE Corporation, a division of SL Industries(NYSE MKT:SLI), and a world leader in the design and manufacture of high-efficiency electrical power quality solutions for commercial and industrial applications, today announces the introduction of its new High Frequency SineWave GuardianTM motor protection filter.

MTE’s High Frequency SineWave Guardian™ Filter is the first and only motor protection solution optimized for high frequency motors. High frequency motors, such as permanent magnet motors, are gaining use in various commercial and industrial applications due to their improved power efficiency and energy density. Energy savings can be further enhanced when these motors are used in conjunction with a Variable Frequency Drive (VFD).

The High Frequency SineWave Guardian™ Filter delivers unequaled performance in protecting against the effects of pulse width modulation (PWM) waveforms generated by VFDs at the high switching frequencies by high frequency motors. The High Frequency SineWave Guardian™ Filter is more efficient and tolerates ambient temperatures up to 60C, making it ideal for a variety of applications. The performance of the filter can improve power quality for motors up to 15,000 feet away from the VFD, and itsmodular design and smaller footprint makes it easy to integrate and install. In addition, the SineWave Guardian family comes standard with a three year warranty.

It all adds up to the most advanced sinewave filter and the best value on the market today.

“At MTE, we have seen the rise in high frequency motor use and the many benefits they provide customers”, said Stu Accola, Product Marketing Manager at MTE Corporation. “High frequency motors such as permanent magnet motors are more susceptible to power disturbances and need protection from the power distortion that can happen over long lead lengths. We leveraged our market leading SineWave Guardian™ technology to work with this emerging innovation so our customer’s motors are protected, and they can realize the full benefits of high frequency motors”.
