-- The supply converter is a generic device which can convert from
-- LV to MV and back, and HV to MV and back.
-- The machine is configured by the wiring below and above it.
--
-- It works like this:
-- The top side is setup as the receiver side, the bottom as the producer side.
-- Once the receiver side is powered it will deliver power to the other side.
-- Unused power is wasted just like any other producer!
