Re: modulated dimmer "switch"

Do they make cheap signal modulated (verses turn with a wheel) dimmer

I want to control some display lights, 5 channels, about 300W per
channel.

Modulate with analog io board. (not an exotic pattern, maybe they even
sell
simple sequencing units with multiple channels .. I've seen slow
switched
xmas lights that do that)

Thanks

Hi, 2. Crydom makes a proportional control solid state relay, which
accepts a 2-10VDC input and outputs phase control of AC (like a lamp
dimmer). The appropriate part number is 10PCV2415, and it's available
at Newark for about $87 USD each. That's the store-bought solution,
and at over $430USD it sounds like it might be a little pricey for you.

If you want something significantly cheaper, and you have "advanced"
electronics assembly skills, I would recommended the Velleman K8064
kit. It is rated for up to 375W control at 120VAC, and it's about $30
each in unit quantities from their distributors. You can get more
information about this kit from the Velleman website:

$150USD sound a little better? I don't think you're going to get much
lower than that for 5 optoisolated AC controls.

Good luck
Chris
