Is it normal for a back UPS too be warm when connected to mains power?

hpw · ‎2022-02-18

Hi,

I recently bought a BX750MI UPS and the UPS appears to be warm even when it is fully charged and pluged into mains electricity. I do have around 40w of load which is just 10% of the rated capacity.

My ambient temp is always 25-28 degrees.

I've never used an UPS before so is this normal or should I be worried?

Thanks

Hi Jon,

Thank you for your reply. I have this problem sorted with customer support already. The UPS is just like 2 to 3 degrees above body temp and the customer support department said this is all normal. It also has something to do with the ambient temp so I placed my UPS at a new location in the room that is cooler and better ventilated.

Again thank you for your reply, this can be marked as solved now.

Hi @hpw

Thank you for reaching out to the SE Community, my name is Jon and I will assist you with this query.

Apologies for the late revert on this post. Are you still having the same issue with the UPS? Since the UPS is being charged when plugged in, it can cause the battery temperature to rise, may I know if it is warm to touch?

Will you be able to compare how hot it is?
