This subcompact from Tripp Lite is simplicity itself.
There are no switches on the front panel, only two LEDs marked Line on and Backup on. A
bit of a hunt revealed a small on-off switch in the back, nestling below the power inlet.
This is another UPS with good performance, but for output
regulation. And that has resulted in losing what could have been a possible top five
position.

Sub-compact 250 VA offline UPS. Simple design and operation. Two power outlets. Unlike the other Tripp Lites, no software control. Low regulation for Indian conditions. Rs 6,250. Ranking: 11 (of 17 tested) Efficiency: 95% at 140 W Switchover time: 7.2 ms Backup time: 12 minutes |
The 250 was able to cold-start a 250 VA load,
delivering a minimum voltage of 258V. Its battery float voltage is also within limits.
While doing the short circuit test, the fuse blew (in fact, this is the only system in
which the fuse blew) and as no replacement fuses were provided, we were not able to
complete the test.
Overall, a very compact UPS which is effective if your
mains supply is known to be fairly stable.
Also very compact, for desktop use.
