>-bob I tried to use a Trust UPS to transport a GPSDO for a demonstration so that I would not have to wait for the warm up and stabilisation period. The attempt failed because the UPS cut out after a few minutes despite the UPS being proven capable of running a 60 Watt light bulb for an hour. After emailing the distributors it turned out that the unit was designed to cut out if the load was not high enough. The 8 Watts the GPSDO used was not enough in this case despite the UPS theoretically being able to support it for over 7 hours. You may need to check out the specification of the UPS to see that the minimal loading will not be a problem if you are looking for a long support time from a UPS.
