Dear Community,
I need to acquire a UPS to supply a small motor. The motor is a vacuum pump that must not be interrupted (during say a short power outage). I am concerned about how to deal with the high in-rush current normally associated with motor starting and how this may effect the operation of a UPS and especially how to specify the power rating of such a UPS.
The motor sige is 0.12Kw however the in-rush start current could normally be expected to be about 5 to 7 times the run-current for a short period.
Can any experienced person in these matters suggest how I should specify the rated power of such a UPS. Do I need to take any other factors into account - such as some some sort of UPS with a soft start facility or UPS especially associated with motor start in-rush currents. ?
Thanks in advance for any assistance.
