MTE Solutions Catalog

High Frequency SineWave Guardian ® Filters transform the output of Variable Frequency Drives (VFDs) to a near perfect sinusoidal waveform for the best level of protection for high frequency motors. MTE’s unique, patent-pending design comes in a smaller size than traditional LC Filters, and offers higher performance and better efficiency. Increase motor life Reduce motor audible noise Reduce radiated emissions High Frequency SineWave Guardian ® High Frequency SineWave Guardian ® Filters High Frequency SineWave Guardian ® Filters HF VFD HF Medium Voltage Motor HF Motor HF Motor HF VFD HF VFD Application Configurations: Extreme Long Lead to Motor Long Lead with Step-up Transformer Multiple Motors High Frequency SineWave Guardian ® Filters • Determine voltage and frequency requirements • Reference motor nameplate to determine motor HP or kW and Full Load Amps • Verify motor meets inverter duty standards per NEMA MG1 Section 31 • Select filter based on Motor Full Load Amps Do not exceed filter’s maximum current rating (amps) • Determine derating requirements Reference Performance Specifications table Understanding the High Frequency SineWave Guardian ® Part Number: Current Rating 0080 is 80 Amps 0600 is 600 Amps Voltage Frequency Code D (380V – 480V) Optimized Carrier Frequency High Frequency Maximum Motor Frequency SineWave Guardian ® Type M=Open Magnetics (No Enclosure) SWG X _ _ _ _ X-HF CC MMM Specially designed for high frequency motors to reduce voltage distortion, improve efficiency, and extend motor life.
