No no. That's a normal UPS that supplies AC power. I have one like that and I'm sure many of us have one of that kind. I am looking for an uninterruptible DC supply, which does not need an inverter and hence should be more efficient and compact. Look at it as something like a DC adapter which would supply DC power adapting from either mains or from a battery if mains supply cuts off. (Just take off the inverter from a normal UPS.) Having said that, if such device is not available, I am looking for a normal UPS, but with a very compact size (less VA rating), preferably wall mountable. I found some local UPS makers' contacts from the web. Will try reaching to them in the coming week. Mayuresh. _______________________________________ Pune GNU/Linux Users Group Mailing List
