On my twin toroidal power supply, I had some problems with supply to the house dropping below the legal voltage
Once it dropped below 200V, which was unacceptable and caused all sorts of issues.
so I fitted one of these APC Line-R 1200VA Automatic Voltage Regulator - LE1200I
It solved that problem instantly
Since then western power faitted a voltage monitor and within a few weeks of seeing the readings, dug the road up and fed our place from the other end of the line and voltages are all within spec so I guess that bit of kit is redundant.

Thanks for the info.

My unit is a twin toroidal so sounds like I do not need to worry at this stage about a new power supply. I may well measure the 12V line and see how it looks.

Probably wouldn't hurt to replace the 20+ year old electrolytics

Just for reference I have found on eBay HP Server PSUs that appear to be very cheap. I think they might be a good, cheap, reliable replacement for the toroids.

yeah, but I thought they were cheaper than that before. Someone gave me a couple and I have not used them yet but I thought they were half the price. Maybe I am mistaken. At that price they are close to the price of a new supply from Meanwell.

Sorry, re-reading this thread as I was looking to upgrade a power supply and realise the power supply needs to be 36V but those server PSUs are only 12V.
