Need help with cap for CVT

Mikael Abdellah · 15th February 2005, 07:17 PM

I have got a nice little UPS that was given to me by a close friend of mine. The UPS has a CVT (constant voltage transformer) but it needs a new cap. What cap-types are best?

Maybe if yu gave some details on what that particular cap does, you'd stand a better chance of an insightful reply. The answer could be anything from ceramic to tantalum electrolytic, with film caps and regular electrolytics inbetween.

Well presumably he means the ferroresonant capacitor, in which case one rated for continuous duty at the voltage and frequency will suffice. Look at motor run caps (usually oil-filled film and foil construction).
