WTC Info regarding NCR "standby power module" 4096-0800
Howdy all......Been looking for a schematic for this UPS which doesn't seem to be on file at NCR anymore. P/N for this 800va unit which is in a stand-alone cabinet is 998-0627324. Uses 2 x 12v batteries in series just to jog anyones recollections. NCR help link suggested these may have been made by another company but didn't remember who.....anyone else out there know about this? Basic problem is that it doesn't seem to recognize a valid mains supply causing relay K2 to be activated. Otherwise the inverter works fine. Any help appreciated Gord |
