I'm intending to buy a lab power supply, high likely a .. I'm thinking about a Korad KA3005D (see picture below).
It does not come with cables for the Red + and Black - terminals, and I (also) would like to have a plug to use power not only via the (4mm) banana plugs, but also by screwing it to the same terminal. I'm intending to create a cable myself.
- For connecting the power cables it can be either connected to the banana plug or to the screw. On the cable, a half round iron 'circle' is needed … how is such half round thing called to connect to it? I mean the 'plug' that needs to be added to the Red + and Black - terminals.
- What is the (inner) diameter (if it is standard)?
