The auxiliary power supply has the only aim of keeping the capacitor  charged.

Consumption is therefore minimal. The power required is less than

5 W. In order to re-instate the rated power value in the capacitor

after an operation, there is an inrush of 15 W for a duration of a few

tens of milliseconds.

For the reasons indicated above, both for the

DCO and for the SCO version it is necessary to supply the auxiliary

circuits which recharge the capacitor with a continuous auxiliary

power supply of 5W (this value can reach 15W for a few milliseconds

immediately following each operation). Careful selection of the

components and a precise design make the electronic multi-voltage

feeder extremely reliable, unaffected by electromagnetic interference

generated by the surrounding environment and free of any emissions

which may affect other apparatus placed in the vicinity.

These characteristics have made it possible for the V-Contact VSC

contactors to pass the electromagnetic compatibility tests (EMC)

and obtain the CE mark.

Overheating of the contacts, generated at the moment they separate,

causes formation of metallic vapours which allow the electric arc

to be sustained up to the first passage through zero current.

On passage of zero current, cooling of the metallic vapours allows

recovery of high dielectric resistance able to withstand high values

of the return voltage.

For motor switching, the value of the chopped current is less than

0.5 A with extremely limited overvoltages.
