    Sylvia this is a great question as a career engineer/ops guy in the telecom industry one that is not focused on enough in the longarm world.

    My wife has an Amara and an Avante with Pro-Stitcher so I have already been down this path - it is crucially important for a longarm to be connected to first a UPS and second a surge arrestor - to not do so is like driving a car without an airbag or seat belt. The surge arrestor stops voltage spikes and the UPS protects from power outages and/or low voltage (known as sags).

    Imagine you are quilting along at 1500 stitches per minute on a run across the quilt and the power quits: your needle rips the fabric, hits the scissors you now can't see cause its dark, and knocks the machine out of timing. Not only is the quilt damaged but you are out of production until you can get the timing reset.

    A UPS would have allowed the machine to run for many minutes allowing you to finish the pattern and gracefully power it down until power came back on.


    Double check my data as I am on the road with the wife at QuiltCon but my memory is the Avante draws 3.5 amps and has a 100w rating for the Prostitcher - this would mean the combination draws ~520 Watts worst case (there is deeper math but Watts is approximately Volts (120 nominal in US) times Amps (in this case 3.5) and then add in the 100 Watts for the Pro Stitcher).

    To provide a safety margin target a UPS that is slightly higher - say 600 Watts - here is an example from APC - will allow up to 46 minutes run time (don't count on that much - advertising spin - but 15 minutes or so is easy).

    Ping back on the forum if you need more info.

    Keith, Great information. I am getting my Amara 20 (without the Prostitcher) this coming Friday and my husband is looking at Surge protectors and said there are a few things to consider. He wants to know how many joules and what is the clamp (evidently how much electricity gets through before it cuts off). He wants to be sure to get the right thing.

    Thanks for getting back to me so quickly.  The links are a bonus. We'll have our surge protector in a few days.
