PCB Connectors

Thread starter #1
Hello I am making a PCB Board whose input is 50V(dc) and 40A(dc), and output is 600V 4 A. I am not sure how to connect my board through external wires from power supply and to load.
Please someone guide me how to select connectors.
Thank you

If you can find suitable PCB screw terminals or barrier strips that could work. But for 40A or 600V you might just want to get solder-down screw points to which you can connect wires to that have ring terminals on the end.

If you want to get real fancy there are also anderson power poles which are hermaphroditic connectors that can snap together to make a connector in various configurations. There exists a counterpart that goes onto a PCB so you can plug wire-to-wire or wire-to-PCB. They are crimp terminals for the wire-end so you can use a budget crimper made for them, the official $$$ crimper, or a carefully selected non-insulated crimper that looks similar (that's what I do). If this is for a production product you definitely want the professional crimper.
