Hi: I've got aWild Heerbrugg ARK 2 surveying north finding gyroscope on order a= nd it needs a 3-Phase 400Hz 115 VAC power=20 Supply to drive the gyroscope motor. I expect that power needed is less than a watt. I've been searching for ov= er a week and so far have only found supplies=20 that deliver many kilowatts. Any thoughts on where to buy a ready made supply or plans to make one? http://www.prc68.com/I/North.shtml#Wild I expect what I'm looking for would be used to test aircraft instruments. --=20 Have Fun, Brooke Clarke http://www.PRC68.com http://www.end2partygovernment.com/2012Issues.html http://www.prc68.com/I/DietNutrition.html --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
