ELCU-200

Anyone familiar with these ? I used them quite a bit but was wondering if these can be used on 0-10 volt dimming. Looks like loss of power emergency circuit bypasses the 0-10 at full brightness.

I do not believe they can be. When the elcu is used in conjunction with other wattstopper products, such as the lmrc-211, the lmrc will open up the 0-10v circuit to make sure the lights go full bright.

Circling back on this - if the LMRC isn't listed as a UL924 device, can it be allowed to ensure the 0-10v is shunted? This is basically relying on the power to go out at the LMRC and it default to 0V. There isn't any communication between the ELCU-200 and the LMRC. I can't find an answer on this, but I'm tempted to send a question to ICC.

I have an office building under construction right now that uses this same setup, and it did not occur to me that it doesn’t override the 0-10v dimmers that almost every fixture is connected to. But I’m not the design engineer either.

Here’s the detail…. They will energize at whatever level the dimmer is set to.
