Different configurations
Figure A :
Standard configuration, use a separate control
voltage.
Figure B :
Connection to one of the analogue outputs of the K8000 interface card. If
DAC1 is used then the circuit can be controlled with the demo program,
"dimmer".
The circuit can also be tested with the test program of the K8000.
Figure C :
Internal reference voltage used as control voltage.
