MTE Corporation Introduces Line Extensions for Matrix® AP Harmonic Filters and SineWave Guardian™ Filters

Expansion ensures availability of unparalleled performing Matrix AP and SineWave Guardian for the widest range of customers and applications.


Menomonee Falls, WI – October 31, 2018 – MTE Corporation, a world leader in the design, manufacture, and distribution of high-efficiency electrical power quality solutions for commercial and industrial applications, is pleased to announce the expansion of its best-in-class SineWave Guardian Motor Protection filter to 600V; 50/60Hz and its industry leading Matrix AP Harmonic Filter to 208-240V; 60Hz.

“The expansion of the SineWave Guardian to higher voltages and of the Matrix AP to lower voltages as standard products will allow us to provide our best-in-class performance to an even broader range of applications for our global customers.”, said Z. Zakaria, VP of Business Development and Product Management at MTE.

The Matrix AP helps customers meet IEEE-519 requirements for harmonic control using the most advanced technology available for passive filters in the market today. Compared to other filters, its patented Adaptive Passive technology is more effective at reducing harmonic distortion over a wider load range and features lower distortion at low loads. Since most loads run at less than 100 percent, this unique capability makes the Matrix AP the most efficient harmonic mitigation tool available. The addition of the 208-240V filters to the existing line covering 400V – 690V will be beneficial to machine builders, commercial builders and customers in regions where older power systems are prevalent.

The SineWave Guardian eliminates the high frequency content and voltage peaks of Pulse Width Modulation (PWM) waveforms generated by Variable Frequency Drives (VFDs) to enhance system efficiency and extend motor life. The new 600V capable filters will match the unequaled performance of the existing line, including characteristics of: low voltage drop, better than 5% THVD at 2-3kHz switching frequencies, and reduced losses. Its ability to operate with cable distances up to 15,000 feet and in an operating temperature of 60°C enable its use for almost any application.

MTE will showcase the full capabilities of the Matrix AP and SineWave Guardian product lines in booth #725 at Rockwell Automation’s Automation Fair in Philadelphia on November 14th and 15th.
