Sometimes I get power drop outs for about 1 minute or so, so I was wondering what type of UPS should I use?
Keep in mind that a UPS also consumes power, for example my 3kVA unit uses about 100 Watts just to keep the batteries floating and it's electronics running. If there is a 1 minute power drop, your power socket that now draws 1250 Watt max will have a much higher load for a few minutes, to fully charge the batteries again + the normal load of your machine, this might push your breaker over the edge. Make sure to do the math before you shell out money.
