Do you mean the standarded Sensor Dimmer Modules, and not the switchable Thur Power ones?
Niether. I'm looking for D20SWs (https://www.etcconnect.com/About/Im.../Sensor-Dimming/Sensor--SineWave-Modules.aspx)
I wonder how much of the ETC sinewave rack was a response to Strand sinewave dimming? I have only seen these installed at classical music venues. At least with Strand you could usually swap a misbehaving sinewave module with a standard one (Most of the time on at full, anyway). Of course, now obsolete.For a company that made easily the most stable dimmer ever in the D20 they certainly whiffed it with this product.
I'm pretty sure it was one of those things that sounded like The Future of Dimming® at the time, but in practice very few people were willing to pay the substantial premium for what turned out to be a very minor benefit. If they had caught on more widely, then I suspect most of the issues would have been ironed out over time. They are far more complex than a D20, and the power components (can't remember offhand if they used MOSFET or IGBT...) are just inherently less robust than a big ol' SCR.I wonder how much of the ETC sinewave rack was a response to Strand sinewave dimming?
