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 a customer calls requesting new power cubes for their 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. The customer 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 the customer has an old style SD-12000, they 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...

The part number for the upgrade kit is 1015A1008.

Instructions are included in the kit. The Packs department assembles these parts so that they are fairly easy to install.
Instructions are included in the kit.
