ADVER TISEMENT Pushing Expectations 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 fi lters. 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. Yaskawa America, Inc. has been building packages for the HVAC industry since 1988. Over that time, we have worked rigorously to evolve our products and exceed industry standards, while ensuring an exceptional customer experience. Yaskawa embraces the challenge of supplying an essential product into a growing and changing market. Not only does the HVAC Matrix drive provide outstanding harmonic performance, but 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 the following: • • • • • • • • Integrated input fusing to provide 100kA SCCR Eco-Mode to achieve near across-the-line THD Integrated C2 EMC fi lter Embedded BACnet communications (BTL Certifi ed) 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 Z1000U HVAC Matrix Drive Yaskawa’s latest offering, the Z1000U HVAC Matrix drive, provides extremely low harmonic distortion in a space-saving design, along with the same HVAC-specifi c 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 fi lters or multi-pulse arrangements. Available NEMA 1 models include ratings of 1 to 100 HP (208V) and 7.5 to 350 HP (480V). Z1000U is offered both as a stand-alone drive, as well as in packaged Bypass and Confi gured solutions. 1-800-YASKAWA (927-5292) or (847) 887-7318 | | input #53 at
