Refurb. project - Apple IIc Power Supply Question.

["Aage Rettvin" <aage.rettvin@c2i.net>]

I'm  refurbishing the following apple systems.

2 x Apple IIc

Power Supply units:

Now, here I would need some technical assistance.  My IIc's came without
PS-units/cables.    As voltage is different in my region  (220V/50 Hz).  I
dont think I can acquire the US-type power-supply's unless there is a
voltage switch built-in.

If so, I would require 2 sets of  the  'power connector-plugs'  that
conncets into the computer with  marked cords followed by a pin-assignment
scheme.

Is this an Apple-specific PS-plug/socket or is it commonly used  also today?
In that case, it might be easier to source alternative PS-units in my region
if I knew the type-specification /designation used for the plug.

Appreciate your feedback on my inquiry!
