Of the UPSes that kept the test bed alive for between 21 and 26 minutes,
SMK-2000A lasted the longest with a runtime of 25 minuters, 41 seconds. But considering that the unit
is rated at 2000 VA, and not 1500 VA as requested for this roundup, this unit really should
have outlasted the other UPSes.
Even if you don't know anything about UPS power ratings, it's easy to see that
something rated at 2000 should contain 33 percent more of whatever than something rated at 1500.
So, in theory, the Powercom SMK-2000A should have lasted about 33 percent longer than average, which,
for this roundup, was 24 minutes. Test Center engineers figure that the Powercom UPS should have
lasted about 32 minutes. But just because it did not last that long doesn't mean that the Powercom
UPS is not a worthwhile product.
The front panel indicators on the unit are good. It features separate bar graphs
for load level and battery level, with additional indicators for line and battery status. The
back panel features six protected outlets along with a pair of RJ45/RJ11 jacks for protecting
network equipment from voltage transients. Of course there's also a serial port for communication
with a server.
The documentation included with the Powercom UPS looks amateurish, but it is
complete enough to refer to and written well enough to be easily understood. The output of this
UPS is a clean sine wave regardless of whether it's on AC power or battery.
