BeePre 2 Voltage Check Terminal 1 and 11

[Jimb0]

Hello. I just built a BeePre2 with output and TwoQuiet upgrade. All voltages checked out except for terminals 1 and 11. I'm getting a reading of 220V on each terminal.

I'm getting a reading of 220V on each terminal.

What was the expected value?

 

[Jimb0]

I think I figured it out. I was looking at the TwoQuiet manual when I tested the voltages for Terminals 1 and 11. This was after I added the 5w 22ohm and 270ohm wirewound resistors between 31-39. By adding these resistors in parallel with the existing resistors, this should increase the voltage because the voltage drop will be less on those resistors. Am I correct?

My other question what does the B+ Raw mean in the output manual upgrade?

 

[Paul Birkeland]

Yes, the added resistors in the power supply bump up the raw B+ a bit so it will work better with the hybrid shunt regulator circuit.  B+ raw just means the B+ before regulation.

Thank you PB!
