I have had an MGE Pulsar Evolution 800 Uninteruptable power Supply for about 8 years through which my computer and other sensitive kit is fed and I serviced it with new batteries in January 17.<\/p>\n

This UPS delivers 800VA or 520 Watts (Calculator for Watts\/VA HERE<\/a>.) and is at 67% loading when in use, giving a back up time of 9m 35s, which is more than adequate for my needs.<\/p>\n

In early February the UPS stopped working completely, no output or indication of power in, the one I have cost \u00a310 second hand off eBay so I couldn’t complain when it stopped working.<\/p>\n

\"MGE<\/p>\n

Before looking for another replacement, I opened it up the check for the obvious, such as internal fuses blown or PCB track damage, looking  near the power regulator stage I noticed a bulging capacitor which is a sure sign that it has failed.<\/p>\n

Everything else passed a visual inspection, so I bought a pack of 5x 10uF 450v 105c capacitors from eBay for \u00a31.59.<\/p>\n

After changing the capacitors, I measured the old capacitors and they had both failed as the meter should be displaying 9.5uF to 10.5uF.<\/p>\n

Once reassembled, I powering up the UPS after inserting the batteries, the UPS kicked in to self-test mode and was working \ud83d\ude42<\/p>\n

Everything is back in place working and I have software monitoring its performance and everything is looking good so far.<\/p>\n
