Moeller DV5-340-5K5 Frequency Converter Converter DV5 340-5K5 5.5 KW

The DV5 series frequency converters convert the voltage and frequency of an existing three-phase network into a DC voltage and generate a three-phase network with adjustable voltage and frequency from this DC voltage. This variable three-phase network enables the stepless speed control of three-phase asynchronous motors.
