ETC LMI SD Single Dimmer
SD Single Dimmer
ATTACHMENT: SD Individual Dimmer Manual
There are a couple of styles of SD12000 dimmers. The "old" style used two cubes mounted to the heat sink. We no longer have any of these old cubes, nor can we get any more. If you requesting new power cubes for your SD-12000 dimmer, you must determine if it is a "old" or a "new" style. There are no changes visible from outside of the dimmer to help you determine this. You will have to open the unit to see if there are two cubes attached to the heat sink (old), or one cube and a small green circuit board with a thermal switch between them (new).
If you have an old style SD-12000, you will need to purchase an upgrade kit to replace the cube. Included in the upgrade assembly is a new cube, firing card, heat sink, etc... Here is a run-down of the parts:
Note: Some of the parts are on very limited access so repairs and upgrades are becoming harder to do.
