do MW drivers provide 10v on DIM leads?

As the title says.
I suppose they do but I am a noob..

1-10v dimming is what I've seen. For pwm dimming you have to get the b version.

Yes you can use 1-10v PWM with the B version of the drivers.

The way PWM modulation works on these is there's a low pass filter, so your PWM is essentially converted to a DC value between 0-10V.

Dim leads source 0.1 milliamps to your 100k ohms dimmer pot. Voltage = current times resistance so 10 Volts = 0.0001 Amps X 100,000 Ohms.
The PWM controllers source or sinks a current (at 10 volts or 0 volts) that blocks or shorts out the Dim wire current many times per second.
