Inverter units are DC supplied and have built-in capacitors for smoothing the DC voltage. Also the dU/dt filter is integrated inside the module. The electrical connection to the common DC bus is fuse protected. An individual inverter unit can be disconnected from the DC bus, either by a fuse disconnector or by a DC switch.
The R8iLC multidrive modules have the best power density in the market and can be connected in parallel to achieve higher power. The has quick connectors for both DC and motor connections.
ABB's inverters always come with the state of the art direct torque control (DTC), which provides precise speed and torque control for all applications and supports virtually any type of motor.
