Tru-Universal Single Pole/3-Way Dimmer, White
(2 Reviews)
Rated 5 out of 5 by from This is a great dimmer at a good price I just purchased and installed this 0-10v dimmer for a light my wife wanted that was only dimmable via 0-10v dimming. The best feature of this dimmer is that the "Constant memory returns lights to previous level after a power failure". It is very easy to connect and comes with covers for two additional covers in addition to the white. I bought it at a local electrical supply house and it was very cost effective compared to buying one online. I hope it is reliable, it will get a lot of use. Curiously Legrand products did not show up in internet searches for 0-10v dimmers.

Does it require a screwless switch plate?

Asked by: Vicki
Good Morning, This dimmer will work with any wallplate that has a decorator style opening on it. It doesn't have to be one of our screwless ones. Hope this helps!

does this require 120v at the switch to operate, or will it run on the 10v passing through?

Asked by: rumely
Thank you for your question regarding the Radiant 0-10V dimmer(Model # RH4FBL3PW). This dimmer does require 120V at the dimmer to function on/off. The dimming is controlled through the low voltage wires(grey/purple). Radiant products 1.800.223-4162 opt 3 Mon - Fri: 8am - 8pm EST (excluding holidays)

Asked by: Ruben
Good Morning, 0-10V dimmers are typically not rated by wattage. They are rated by Amperage. They can handle 10A max at 120VAC or 5A max at 277VAC. Hope this helps!

Do I need a ballast/driver for the dimmer to work?

Asked by: Kadie
Yes this dimmer is a 0-10V dimmer. It is designed for 0-10V ballasts/drivers. If you do not have a 0-10V ballast this is not the dimmer You want. I would reccomend our RH703PTU it is our Tru universal dimmer designed for a wide variety of light loads.
