The Board supplies the operating voltage for the three-phase consumers and the measuring and control devices. An integrated current transformer measures the current for the reactive power controller.

The Board integrates two 3-phase PFC capacitors in delta circuit with corresponding bleeding resistors. One of the two capacitors is detuned for protection against harmonics.

The Board integrates three capacitor contactors which can be actuated manually or by means of a reactive power controller.
