Ballast Interfaces and 2-Wire Ballasts
In some cases, dimmers are wired to ballast interfaces (provided optionally by lighting suppliers),
rather than directly to the ballasts. A few interfaces are driven from a standard AMX Lighting
incandescent channel, while most use FDB dimming configurations. The following table lists
compatible ballast interfaces.

Notes:
1. The Lightolier ballasts require a proprietary DC-signal interface (including low-level trim). The AMX
Lighting controller module handles load power.
2. The Lutron HP-2, 4, and 6 interfaces accept 120 VAC input. The load can be 120/277 VAC (including low-
level trim). Interface includes power control to ballasts.
3. The Lutron GRX-FDBI accepts 120 VAC input. The load must be 120 VAC. Interface includes power
control to ballasts.
4. The Prescolite ballast interfaces are optional. The AMX Lighting controller handles load power.
