Flexible Inverters

The K series of three-phase inverters convert a DC voltage into a three-phase, sinusoidal AC voltage. They are rotary inverters that operate with MOSFET semiconductors and pulse-width modulated control of the power output stage like the single-phase devices. The modular expansion of the device features and functions as well as adaptations required by the customer can be achieved easily. They are also designed for use in industry and railway vehicles.

The rotary inverter has two freely programmable operating points. This allows for the power supply of two different users. An example: The inverter supplies laptop connectors in operating point 1. This is changed to operating point 2 when the train stops. Fresh air is now blown into the passenger cabin with the aid of a battery-saving voltage and frequency startup that is adapted to the fans.
