Hello,
This circuit board seem to be power supply that lights up a lamp/light to a projector. It seem to supply 70 volts to the light bulb.
Having what appear to be 3 optocouplers would indicate the supply to the light bulb must be 70 VDC.
So I am wondering what low voltage do I supply to these wires and in what manner. There seem to be 1 white and 4 green/brown wires that feeds the optocouplers.
I would think the white wire is the ground and the other 4 wires power from a DC power source.
Pictures included.
Thanks.
