-- 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!
