My mistake, I didn't know the "B" represented dimming capabilities. I was looking at a few lists where the specific drivers with dimming capabilities were listed and the HLG-320H-C1400B was never listed for some reason. The HLG-320 is cheaper though so that's good. For input voltage, when calculating my fixture's requirements it comes out to 183 which means the driver can support that and more. What are you running on your HLG-320 @ 240V?why? as I see it, the only difference between the HVGC-320-1400B and the HLG-320H-C1400B is the HVGC-320-1400B allows for higher input voltages, other than that, they are the same (except the cost).
what is your planned input voltage? I'm running HLG-320H-C1400B with an input voltage of 240V. I also attached a 0-100K potentiometer to the dimmer leads which works well. I just don't know how to gang three drivers on one potentiometer, I know sixstring has done it.
they are both dimmable, the "B" on the end of the part numbers mean they have external dimmer capabilities.
Figuring out how to link them together isn't something I'm too concerned about right now. I'm just trying to put a parts list together that I know will work and once that's complete I'll delve into learning how to put it all together.
