The Drives & Motion Division of Yaskawa America, Inc. has released the Z1000U HVAC Matrix Drive, which provides extremely low harmonic distortion in a space-saving design, along with the same HVAC-specific features as the standard Z1000. This single component solution achieves excellent low distortion levels all by itself, completely without the need for additional countermeasures such as passive filters or multi-pulse arrangements.
Unlike conventional drives, Yaskawa’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. It eliminates the need for a rectifying circuit and a DC bus that are used in traditional AC drive inverters. 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, reducing energy costs. 
Also, being a member of the Z1000 family, it provides the same user experience for those already familiar with commissioning and maintaining the standard Z1000.
Other features of the HVAC Matrix Drive include:
- Integrated input fusing to provide 100kA SCCR
- Eco-Mode to achieve near across-the-line THD
- Integrated C2 EMC filter
- Embedded BACnet communications (BTL Certified)
- Multi-language LCD operator with Hand/Off/Auto and Copy function
- Internal real-time clock for event stamping
- High carrier frequency (low motor noise) capability
- 0-400 Hz output frequency
Available NEMA 1 models include ratings of 1 to 100 HP (208V) and 7.5 to 350 HP (480V). The Z1000U is offered both as a stand-alone drive, as well as in packaged bypass and configured solutions.
