Application
The »fpControl Measurement Unit – MU-3ph / DC« is used for AC and DC generators.
Product description
On AC generators, the module measures the AC voltage up to 400 V in three phases and the AC current three times via an external sensor.
When used on DC generators, the module measures the DC voltage in two phases in the range from 12 V to 600 V and twice the DC current via an external sensor.
