The Nissan 625 M is a 500 VA UPS with impressive
performance and was able to cold-start a 250 VA load. It was the only one to give the
Accure a run for its money on backup time. Efficiency was slightly lower at 78 percent,
and the battery float voltage was not within acceptable limits. But of the 17 systems
ranked, only five had float voltages within limits. The number 625 is a misnomer and
doesn’t stand for the VA rating as you would expect.

| This 500 VA UPS weighed in at 15 kg, but matched weight with performance. The only area lacking was the battery float voltage, which was outside acceptable limits. Rs 9,995. Ranking: 2 (of 17 tested) Efficiency: 78% at 283 W Switchover time: 5 ms Backup time: 17 minutes |
In a head to head competition with Datex, the number
one, the Nissan loses out on minimum output voltage. It scored higher on cost per VA and
cold-start, but not enough to make up the gap. It produced 262 V during cold start of 250
VA load. It also achieved a fairly fast switchover of five milliseconds.
On the back, there are four output sockets, provision for
additional external batteries, fuses for the mains and external batteries, and an RS 232
port, all neatly labelled. The control software is DOS-based.
