These VSs are quite old. The latest ones come with a microcontroller program and if there is a software issue, it has to be taken to the company only! Many thanks for your comments and interest!

In this case a 500VA x cos phi AC V-Guard (or about 500 Watt).
These devices always draw my interest because of their protective character on safely feeding through the power line AC voltage. Why I am interested in finding a complete circuit for such a device. Just in case I ever need it.

I am very sure you enjoyed getting this one repaired…( the amount of the capacitors involved). Have a blessed day
