I can control the voltage as I'm using a CV driver: MeanWell 320H-48A.There is no way to control the voltage, the dimmer controls the power or amperage. So the resistance or Ohms of the strips dictates what voltage they will run at a given current or amperage.
JavaCo may not be familiar with the Meanwell CV drivers since so may people here push the CC drivers which do work as he describes.I can control the voltage as I'm using a CV driver: MeanWell 320H-48A.
I can dim both Amps and Volts in this driver.
