Bc2000 (for the BCF2000 & BCR2000)

I measured the power supply connections on my BCR2000 a while ago:
1x 4.9V (red cable), 3x 5.4V, 3x gnd

I suspect a 5v, minimum 2A supply is all it needs. I wouldn't connect 12v past the power supply, it'll probably fry the components.

The supply itself is made up of the following components,
you can find datasheets online:
TNY268PN OFF LINE SWITCHER
4N35 OPTOCOUPLER, TRANSISTOR
YG802C04 SCHOTTKY BARRIER DIODE
