Regeneration Power Unit

A PWM converter is featured in high-speed models, which returns regenerated power that is generated by the motor during the full-load down or no-load up operation to the power supply unit. The regenerated power contributes to the overall reduction in power consumption since it can be used by other electric power equipment installed into he building. The power consumption can be reduced by about 35% compared to an elevator system that is not provided with a PWM converter.
