You're in an industrial environment, right? Seems to me that you could rig up some type of relay between the UPS and the PC so that when the machine is turned off normally the relay would open between the UPS and the PC. With zero draw the UPS should up for a long time, unless there's enough loss from the inverters that would drain it. I've never tried leaving an unconnected UPS on to see how long it would last.
Just a thought... -----Original Message----- From: Ben Scott [mailto:[email protected]] Sent: Thursday, July 14, 2011 5:50 PM To: NT System Admin Issues Subject: UPS with remotable power on/off switch? Hey all, Anyone here ever encounter a UPS with a remotable power on/off switch? We've got a new water jet cutting machine which uses a PC to control it. I'd like to put a UPS on the PC for all the usual reasons. Problem is the PC is inside an industrial control enclosure (not easily accessible). When you power down the machine you power down the feed to the PC. If the UPS is left on it will switch to battery. Doing that every night would be bad. So what I'd like would be a more-or-less standard UPS, but with some terminals I can wire up to a push button or toggle switch on the control panel. Said switch would perform the same function as the built-in switch on the UPS. Their procedure in the morning would be to turn on main power, then turn on the UPS. Shutdown would be the reverse. I've seen plenty of UPSes with a remote emergency power off feature, but I don't think that's suitable for this. Those seem to be intended for emergencies, not regular use. They often require the UPS to be turned back on from its front panel, generate alarms, and/or leave the UPS controller running. -- Ben ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected] with the body: unsubscribe ntsysadmin ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected] with the body: unsubscribe ntsysadmin
