Title: BeePre 2 Power Transformer Input Wiring
Post by: rover on July 13, 2021, 09:32:04 PM

The nominal voltage for Australian households is 230 volts
After wiring the PT to suit 230VAC, do pages 31 thru 34 still apply as instructed?

Hi!  Yes, you still need to build the High Voltage power supply on pages 31-34 as this provides the rectification (AC to DC) for the high voltage part of the circuit.

I know these stages still apply, but only double checking on config due to different voltage input and may have worded the question wrong.

Thanks Sam

On page 25, there is a powerline voltage test.  What voltage did you measure?

Based on that voltage, you can determine which wiring configuration to use for the primary of the power transformer, then we have you test the power transformer (which also helps to know that the correct line voltage configuration was chosen), then you move on with the build.
