Yes I can, you see there can be two things. 1, it can be there isn't enought solicone on your processor. or 2 it could be your fan that went out, fans usually go out like that. My fan just went out too. I recomend going to a computer store and ordering a new fan

MGE Pulsar EX 10 online UPS doesn't work


With the ones that I have seen the ups units have a relay that routes the 110v thru the unit when it has 110v power applied. If you are saying it has no output on batteries only then you may be right about the inverter. SAFELY I would just verify on the board that the DC input from the batteries is correct to test your install. It seems there may be a RS232 DB-9 connection on them with available software for communication with them, if it does I would try it.

My suggestion would be to replace the battery to make sure the battery is not shorting out the UPS. If you can't do that, take out the battery and then replug the UPS back in.

If you still get the same results then that means the main board inside of the ups system is bad and you would need to get a new UPS system.

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!

Hot to test the battery of ups pulsor evolution 3000xl and battery chenged ups shutdown requast or no


Buy a CB10 10 ohm ceramic resistor (10%)

Alagator clips on (+) (-) and on the resister. If the battery can not hold the charge after one minute above 12V DC, but drops very quickly that battery is due to be replaced. Very simple test and cost hardly nothing.

Fan has not turned on


I think the fan should work all the time. There might be and option in the software to turn on the fan only if the system overheats.
