It's a bit more complicated than that, but yes, you could build a electronic interface. A PCM driver uses the potentiometer to vary the drivers output. But there is no guarantee the voltage across the potentiometer is 0-10 volts. If it is, a simple interface would work fine. These fixtures are also available with electronic drivers that will interface with the reef keeper dimmer modules and others, but not from ebay as far as I can tell.
