These models of power units have been studied to obviate to all the situations which contemplate the applications of two power units on tha same machine. In fact, two separated antistatic groups, with output tension 7000 V ( MOD CND/2A ), or 5000 V ( MOD.CND/2S) and with two luminpus switch ON/FF, are put in a single case. To each power unit it is possible to connect four antistatic bars or nozzles for a totale of 20 meters including high tension cable.

The power units have a structure in painted steel.
