Product Description:

The 09.G6.CDA-39B0 is a three-phase inverter produced by KEB for the G6 Combivert IO Inverters series. Positioned between the mains bus and a motor, it converts constant-frequency supply energy into a controlled output that regulates speed and torque in conveyors, pumps, and general automation. The housing is identified as size A, which helps support compact cabinet layouts without requiring auxiliary cooling fans or blowers. By supplying programmable voltage and frequency profiles, the unit allows a PLC or fieldbus controller to match motor behavior closely to changing process demands.

The power section accepts an input of 400 V AC/DC, and under nominal conditions it draws 6 A. Internally, insulated-gate transistors switch the DC link at 4 kHz and produce a controlled output current of 4.1 A, which corresponds to 2.8 kVA of apparent power. This operating range suits standard industrial motor control duties while keeping electrical stress within the intended limits of the drive. An overcurrent trip activates at 8.9 A to shut down the bridge during short circuits, while a 16 A mains fuse isolates the supply during sustained faults and protects upstream wiring.

For transient acceleration, the inverter can supply 7.2 A for 60 seconds, providing extra current for peak load events on a 1.5 kW motor. The enclosure has an IP20 protection class, so the unit is intended for installation inside a closed control panel and provides basic protection against accidental finger contact. Its slim 90 mm width helps conserve cabinet space, while the stated depth, height, and low overall weight make rail or screw mounting easier in tightly packed assemblies. The compact housing also supports close side-by-side placement when several drives are installed in the same enclosure.
