UPS Room Temp.

[Shavner]

Does the room temp for a 40kw, 50kva 380volt have effect on operation or life of the equipment? Presently it is kept at 55 deg F. Can the temp be raised to lower cooling costs?

 

[mpparent]

Absolutely....I would be willing to bet that you could cool to about 68deg, w/ an alarm setpoint of 70 to 72 deg. 55deg is too cold...hanging any meat too? (sorry for the jibe)

Some UPS models have internal temperature monitoring/reporting. That may help substantiate your position.

look at the UPS's nameplate and/or instruction manual, it should have a spec for operation and storage temp limits.

Or else you can import one from my country which will work upto 40 deg.C (104 deg.F). We recently bought with same configuration.

The UPS electronics are not critical here, but the battery life is and it depends on the room temperature. With lower temperatures you extend the battery life. Cost of replacing batteries is usually significant.

 

[Ares]

Battery life is reduced at higher temperatures - for every 15 degrees F over 77, battery life is cut in half. This holds true for ANY type of Lead-Acid battery, whether sealed, gelled, AGM, industrial or whatever.

I agree with Ares, if your batteries are in the same room as the UPS, the battery temperature is a much bigger concern than the UPS temperature.

High temperature will shorten battery life as noted by Ares.

Low temperature is also a concern, as the lower the temperature the lower the output. Batteries want to be at 77 degrees, your current 55 degree temperature is too cold for them.

C&D Batteries (

also has some great battery information.

The higher the temperature, the more power you'll get out of the batteries (in minutes) but the shorter the lifetime (in years).

The reverse also holds true.
