The power supply bee provides the voltages U_B+ = 15 V, U_B- = - 15 V and U_B2.
The value of U_B2 depends on the jumpers at JP1 and JP2 according to the following table (-- indicates the jumper position):
| JP1 | JP2 | U_B2 |
|---|---|---|
ooo |
o-- |
5 V generated from U_B2 |
--o |
--o |
5 V generated from U3 |
o-- |
ooo |
U3 |
