[QUOTE="Vipersan, post: 914070, member: 325666"] Ok ..took a current reading of the actuator loading in amps whilst the dish was in transit.. Approx 1.5 amps ..which surprised me a little .. I expected more.. So if both motors were active at the same time ... approx 3 Amps .. Now I always prefer to allow for loading (wind etc) and problems encountered .. So allowing an extra 0.5amp for each motor ...we are back at my original approximation (2 amp per motor) 4 amp in total .. So at 25v roughly this would hopefully equate to 24 x 4 my estimate is therefore 100W or 100VA The psu that failed was 200W ..so no excuse for failure imo but still ...if I went down the torroid route which I'm seriously considering .. A dual secondary 12v (x2) seems a sensible option .. Thus I would have 2 speeds Slow and very slow ..the rating of which would I assume be 100VA Do I have this right ? rgds VS [/QUOTE]
