The new SIEIDrive AVRy series can achieve energy savings of over 50 percent compared to conventional drive control systems.



The new SIEIDrive AVRy series of regenerative frequency converters, designed for use in civil lift engineering applications, exploit the potential of the energy generated by the movement of the cabin and its vertical load and convert this into electric power to be regenerated in the power mains. This can result in energy savings of over 50 percent compared to conventional drive control systems
