UTS10BI Transfer Switch

This was originally posted on APC forums on 10/8/2009


UTS10BI

I have a UTS10BI and so far like it very much. After reading the installation guide and user manual I still have questions about the BACKUP2 UPS inlet. In the system configuration and setup for BACKUP2 SOURCE TYPEyou have the option of UPS,GENERATOR or OTHER. The maximum power rating for BACKUP2 is 1800W.

1) Is the power input via BACKUP2 handled the same way as power input via BACKUP1 utilizing all the neat features like load management?
2) Does the 1800W power rating of BACKUP2 mean that if a generator is used it must have a surge rating of 1800W or less or is the transfer switch smart enough to limit it's current intake to 1800W?

Thank you
Eddie

1) Yes, Adaptive Load Management and load shedding are used with Backup 2 just like Backup 1.

2) 1800W is designated primarily since the inlet current maximum is 20a. 80% x (20*120) = roughly 1900w. 1800W is a solid number for the UPS limit and approaches the maximum you can get out of a 20 amp plug while also adhering to code. If the draw on the UPS goes over 1800, the UTS will handle the issue through load shedding and an overload alert will come on. Generally it's advised that the generator be sized at larger than the UPS, so that noise and a transfer from source to source don't become problems. Most household generators are generally well above 1800w so this is not an issue.
