SineWave Guardian for Siemens Drives

For motor protection, there is nothing better.

Motor protection and power quality don’t have to be a mystery. MTE makes it easy. Case in point: our new SineWave Guardian Filter. This best-in-class filter delivers unequaled performance in cleaning the PWM waveforms generated by Variable Frequency Drives (VFDs). The SineWave Filter is sometimes referred to as a band-reject filter or a low-pass filter because it rejects the carrier freqency .  This virtually eliminates high frequency content and voltage peaks, thereby reducing motor heating to give you extended motor life – and less downtime. The SineWave Guardian also offers incredible reliability and durability. It is more efficient and tolerates higher ambient temperatures, making it ideal for a variety of applications from steel mills to oil fields. Its modular design and smaller footprint make it easier to integrate and install. It all adds up to the best SineWave Filter, and the best value on the market today.

These are recommendations only, it is the responsibility of the customer to measure the full-load amps of the motor before to ensure proper sizing of the filter. If your above application goes above  75Hz frequency, contact factory for information on motor de-rating.  Anything above 120Hv requires a high-frequency Sine Wave Filter.
