[QUOTE="dreambox1959, post: 1082550, member: 314801"] relays: i own about 2 hundred of it !! its 5V model 30A (big enough) the 36v power is provide throught a PWM mosfet (20v to 40V progressive) for soft start and landing ! for me i drive a 2meter PM dish and cardiff a 1.8 CM offset : no problem to start move soft start , run with 40V (fast) , slow down near final position. my transformer is DIY model (2x18v + 1 x 8v) Cardiff use a toroidal 2x18v and a separate transformer for µP supply. i want to make a positionner made with discret components (no smd) , easy to build , easily editable , dont care of size !!! here is a complementary schematic: [ATTACH type="full"]128317[/ATTACH] [/QUOTE]
