All MR Frequency and Voltage Converters consist of an electric motor coupled to a permanent magnet generator that reduces the single-phase (1-ph / 230 V) or three-phase (3-ph / 400 V) input voltage into 42 V while increasing the frequency to 200 Hz. MR frequency converters consist of a smooth, robust aluminium casing and depending on the model they
have a handle or a grip frame with coupling or wheels.
