Catalog# DSR12600

Lutron D-600R-WH
600 W Single-Pole Rotary On/Off Dimmer

This Dimmer switch can be used with any transformer listed for sale on this web site to control the voltage output and also turn off the power to the transformer.

This Dimmer turns off by rotating all the way counterclockwise.  Push On/Off styles are not appropriate because you cannot tell whether they are on or off since they are not controlling a light.

This controller is for 60Hz 110V (nominal) only so will not work in other countries using 220V or 50 Hz power.
