Hi all. Anybody know whether there are official standards or unofficial standards for the ordering or arrangement of the front panel terminals for DC bench power supplies?
Many/most old-school power supplies have the order red, green, black (from left to right). Many supplies these days have it black, green, red (from left to right). I won't mention the vertical terminal arrangement in this post. Just the horizontal arrangements.
While order shouldn't actually matter when we clearly know what the terminals are, just wondering why many/most new-school supplies have gone down the road of black, green, red ----- different from old-school. The order of low voltage to high voltage to go with sign convention maybe? Or convenience of wire connections - such as if the black is on the left-hand-side, then the wire can go out to something like a breadboard (or those vertical supply posts on a full breadboard assembly) without needing to cross over other wires etc?
