Hello, I need a UPS for 1kW....my load is approx 400w and need minimum 2-3hours back up. I searched on the net but can't find it any where.... that UPS includes bettry inside its chassis and must be of some brand
Are you asking for a UPS that can put out 400W and keep your computer running for 2-3 hours? You'd need one the size of a bed to do that. That link he posted is saying that at a draw of 50W the UPS will hold for 3 hours. At 400W it'll last ~14 minutes.
hello....! thanks for reply I found a UPS that covers my needs at APC butt its so expensive for me to afford its a 5000W UPS and on 400W it stands for almost 3 hours and price is 105000 PKR.............So expensive
