Innovative Regeneration Unit

7.5~110kW 3Phase 400V Class
Vertical lifting machinery or high inertia loads like elevators, cranes, centrifugal fans and centrifuges contain potential energy and inertial energy when operating. When the motor is operated by an VFD, this energy is converted back into electrical energy when the devices decelerate, lower or stop the load. This electrical energy, called regeneration, flows back into the VFD’s DC bus, causing the voltage to rise.
Traditionally, this regenerative energy is dissipated as heat through dynamic braking resistors, and is therefore wasted. The iRU series (Innovative Regeneration Unit) can provide up to 40% energy savings, by reclaiming that regenerative energy and feeding it back into the AC supply.
