Hi everyone,
Can anyone give me a little advise on this little problem i have; my brain has stopped working and can't think anymore!!! :lol:
From a variable voltage of 0 - 10vdc i need to be able to control a variable resistor, in other words, at 0vdc i need a resitance of close to 0ohm and at 10vdc i need to see a resistance of around 10Kohm. the scale would be preferably linier.
This is to control an electronic dimming circuit. The problem is, my controller card outputs 0 - 10vdc (0 volts being 0% and 10volts being 100% brightness) but my dimmer module is designed to be controlled with a vairiable resistor across an internally generated 0 -10vdc supply to control output brightness. So, if i can use some kind of electronic variable resistor if you like, the dimmer module would just see it as a standard variable resistor across it!
I hope i have given you enough information here to be able to help me, and look forward to a reply soon!
Thanks very much
Dave
