Operating Temperature

06/14/2021 1:58 PM

The operating temperature of a UPS is rated at 0 degrees to 50 degrees Celsius.

Does that means the UPS is going to work at 50 degrees Celsius ambient temperature? Or is it the maximum temperature including ambient temperature plus temperature due to UPS generated heat?

Please help me understand. Thanks.

I would imagine that refers to ambient temperature...where would you measure the internal operating temperature? It probably has an internal cutoff if operating temperature is exceeded....

"Manufacturers specify the ambient temperature range over which the power supply or electronic equipment will operate efficiently and safely."

Ambient temperature, although look at the specs for any information about creating in the higher temperature zone.

Most devices will have reduced functionality - in this case, capacity or duration - at the top end of the scale.

I've seen parts with 50+% sweating as temperatures rise.

A phone call to the <...UPS...> manufacturer's Technical Helpline will settle this.

Ambient temperature is what manufacturers specify. However, I'm certain the longevity of the UPS will be shortened if one must run the system at such a high temperature.
