I want to convert 5 electric blinds from battery to an ac/dc wall transformer. Each blind operates with 8 AA batteries and the motors are rated at 0.6 amp and 7.2 watt. When you hit the up or down button on the remote, all 5 motors operate at once. I want to run them off of one transformer and will wire the motors in series. I know I need a 12 volt transformer (8 1.5 volt AA batteries). My question is amperage. If each motor is 0.6 A, do I need a 3.0 A transformer?
