Hello I have a problem on MGE Calaxy 3000 20KVA UPS. I change the batteries with new batteries when i put it on, the battery status deos not come just give me xxx . before has this erorr "UPS...


The Galaxy 3000 uses a software which has all the data of the batteries used for the commissioning. However if the battery replaced are not of the same specification then the XXX would appear, meaning the software cannot match the specifications. Please try for first principle, check the ac in, check the rectifier and so on. Across the battery circuit breaker (in off position) compare the battery voltage and the charging voltage. This would give you an indication if the charger is working.

My ups is giving dc suppy regular


Do you mean that the UPS runs on battery but does not transfer to AC even when AC main supply is Available? If yes check the AC fuses inside the UPS. I assume you know how to disassemble a UPS, but if no please let an experienced technician handle this as you are expose to electric shock if you make mistake while the unit is open.

Ups temprature fault


From what info you gave me. It sounds to me like it is either too small for the load, or it is in a confined space where heat is building up (UPS has to be outside of a desk office, etc.) or the rectifier is going bad and heating up. I would check to see if it does it by hooking up a small load to it like a radio or something, and if it is in the open, not overloaded then rectifier is bad,I see it alot. I am a Master Electrician and have worked on many UPSs'. Remember that if you keep a UPS loaded to it's full potential (which you shouldn't do) it will get hot. The rule is to only load it up to 80% of it's rating and you will be fine. To find out how many amps it will handle you simply devide the VA of the UPS by the supply voltage. Example: 1200va UPS supplied by 120v. is good for 10 amps. 1200/120 = 12 amps, then it is wise to add 25% more to the watts or amps when sizing them. Also, if it has a cooling fan make sure it isn't blocked by lint and is working, if it isn't working it will get hot fast. Good luck!

No Power


You should measure AC voltage from the output of the transformer to the bridge rectifier, and after the rectifier you should see a DC voltage (you may also read some "ripple" AC voltage on the DC side as well). Check across each battery to see how many volts DC they are receiving (as they will all be in series connection ie one after the other). Batteries are the usual problem with faulty UPS's. You may have a problem battery or multiple problem batteries and they may need replacing.
