Question about UPS Battery Backup Systems
I have a UPS which is designed to work on 60Hz power supply but my utilty service provides power at 50Hz. The UPS gives an error of under cycle voltage and does not work. Please help me to put the UPS to operate. My mail account firstname.lastname@example.org
Unfortunately, it seems that you UPS is mostly designed for 60 Hz. However, there seems to be an exception for 380-415V input / 380-415V output where 50 Hz is supported.
Of course, 380-415V is not usable for IT systems as is, you would then have to transform it back to 208V or whatever voltage your infrastructure is requirering.
Check out the table at page 2 of this document:
One thing that is not specified in this document is if the UPS can be easily switched from one input voltage to another or if you need to replace some parts.
Hope this helps.
