Hi All,
I have back home in storage 2 Switchmode power supplies designed to power Telephone Exchanges (and therefore have very low electrical noise). They are 2.9kW each, voltage selectable between 40 and 70volts.
Anyway, inside them there are 3 450V capacitors, around 350uF each (I can't remember exact details). As these have not been switched on for over 2 years, will it be a good idea to reform these caps before I turn them on. If so, how? I'm comfortable opening the PS modules up, but I don't want to have to desolder the caps to remove them. Does anyone know how to reform hi voltage capacitors
Thanks, Adrian
