Since ther are two UPSs sharing the number seven
position, there is no number eight, and the Omnipro is ranked ninth. Incidentally, this is
the highest ranked Tripp Lite and like most other western models, this one also loses
points in regulation. Like other Tripp Lites reviewed, the Omnipro is also not able to
cold-start a 250 VA load. It is a matter of interest that the Tripp Lites head the list as
far as cost, warranty and compactness are concerned. If only they had better regulation
and cold-start capabilities, the Tripp Lites would have given the winners a run for their
money. Without proper regulation, they turn out to be average performers.

A 450 VA offline in a mid-sized “tower”. Three power outlets. Good efficiency and backup time. Low regulation. Optional software control (not tested). Rs 10,500. Ranking: 9 (of 17 tested) Efficiency: 88% at 259 W Switchover time:9.8 ms Backup time: 11 minutes |
The system comes as a tower model with three output
sockets, an RS 232 port and a reset switch at the back and various indicator LEDs and the
on-of and test switches on the front.
The Omnipro 450 has impressive efficiencies of 88 percent
at 259 watts and has its battery float voltage within limits. Its backup time of 11
minutes is very good and it ranks fourth after the Datex, Nissan, and Trip Lite BC 250 on
this count
The Omnipro like all other Tripp Lites was unable to cold
start a 250 VA load but had acceptable switchover times.
