15-Mar-Yaskawa-Drive-360Yaskawa America released its Z1000U HVAC Matrix drive, a modified version of its standard Z1000 drive to provide low harmonic distortion. The company’s matrix technology employs a system of 9 bi-directional switches that are arranged in a matrix to convert a three-phase AC input voltage directly into a three-phase AC output voltage.

According to the company, Matrix technology reduces total harmonic distortion levels to less than the IEEE compliance standard of 5%, without the need for reactors and filters. The result is a smoother current waveform that reduces stress on the system power supply and infrastructure. Additionally, reduced distortion improves displacement power factor to 0.98 through the entire load and speed range, the company says. The Z1000U is vailable NEMA 1 models include ratings of 1 to 100 HP (208V) and 7.5 to 350 HP (480V).
