I have one of these units which is a Cetronic Reguvolt. It has not been used for years, but I ran it up on my Variac a few days ago and it is not working. Vout increases greatly in the Vin range of 200-250, whereas it should be within 3%. I used a 1kW fan heater as a load.
From what I can find on the internet this units are
pretty simple http://www.powerqualityworld.com/201...oresonant.html but I'm not sure what the implications are for serviceability.
I wonder if anyone has any experience of servicing them and what the specs of the capacitor are? This is an obsolete unit and I've not been able to get info about it from Cetronic. It is so
very heavy that even standing close to it makes my back hurt
.
