| ee5c6c | 1 | -- The supply converter is a generic device which can convert from |
| K | 2 | -- LV to MV and back, and HV to MV and back. |
| 3 | -- The machine will not convert from HV directly to LV. | |
| 4 | -- The machine is configured by the wiring below and above it. | |
| 5 | -- It is prepared for an upgrade slot if this is to be implemented later. | |
| 6 | -- | |
| 7 | -- The conversion factor is a constant and the conversion is a lossy operation. | |
| 8 | -- | |
| 9 | -- It works like this: | |
| 10 | -- The top side is setup as the "RE" side, the bottom as the "PR" side. | |
| 11 | -- Once the RE side is powered it will deliver power to the other side. | |
| 12 | -- Unused power is wasted just like any other producer! | |
