Does anyone know the make model of the triac in the CFS Rentec PM2000 house dimmer control box.
I found a diagram which showed:
SC160D American Microsemiconductor Inc THYRISTOR MODULE,TRIAC
Is this right? Or, is it a different one?

Also, I'm going to replace the front panel POTs on the DM2000 but I was wondering if the pots are linear taper. I know the values are 25k(left) and 500k(right).

Most Triac are interchangeable many use th BTA40400 or the teccor equivelent
the only point to watch is the line load polarity as it may flicker if backwards

I just pried 6 of those off the booth walls and tossed them. Wish I'd have known sooner I'd have sent them to you.

Maybe I'll follow in your footsteps Mark. [Razz]

Can't run them in Kentucky in commercial apps: no UL rating.

I do have a large number of Kelmar dimmers available, though. Louis

Louis.

Is there any way of getting a list of items you still have available?
