Yaskawa America’s new U1000 Industrial Matrix Drive comes in two versions:
A 240-V Class matrix drive delivers 10 to 100 hp under normal duty (or 7.5 to 75 hp heavy duty)
A 480-V Class matrix drive delivers 7.5 to 350 hp under normal duty (or 5 to 300 hp heavy duty)
Unlike conventional drives, the drive has nine bi-directional switches in a matrix to convert a three-phase ac input voltage directly into a three-phase ac output. So, there’s no rectifying circuit or dc smoothing circuit as in traditional ac drive “inverters” … which makes for reduced harmonic distortion.
More specifically, when a conventional ac drive converts power, it distorts the input current and degrades power quality. Matrix technology reduces total harmonic distortion levels to 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. Less distortion also boosts the power factor … and cuts energy costs.
The compact drive can also regenerate power without additional components. Traditional drives utilize regenerative braking resistors to dissipate energy as heat, and that degrades efficiency. In contrast, the U1000 Industrial Matrix drive returns regenerative energy directly to the power supply, increasing energy efficiency and saving money.
The Matrix drive provides the same user experience as Yaskawa’s 1000 series drives. Other features:
• Low Input Distortion Across a Wide Load and Speed Range
• IEEE-519 Compliant (<5% THD)
• Eco-Mode to Achieve Near Across-the-Line THD
• Near-unity power factor
• Integrated Input Fusing Provides 100kA SCCR
