Digital Lighting Systems: Analog 0-10V dimmers are used to dim LED lights that use constant voltage: 12 VDC or 24 VDC

They are compatible with any standard 0-10V wall dimmer and could be integrated with 0-10V lighting controls:
photo-cells, occupancy sensors, daylight harvesting and energy management systems.
( provided by: Lutron, Leviton, Cooper, Wattstopper, etc... )

All the 0-10V dimmers could be controlled as well from an 80-100 KOhm potentiometer.
