NOTES:

1. Compatibility with 0-10V dimmable drivers manufactured by companies other than Thomas Research

Products cannot be assured. Please contact your sales representative for a list of compatible drivers.

2. This device is designed to operate with standard wallbox switches only.

3. UL requires that these modules be installed within the luminaire enclosure.

The SD2 works with two standard wall switches to

provide quick switching between 100% and 50%

light output from LED luminaires.

• Works with 0-10V dimmable LED drivers

• Eliminates need for expensive dimmer unit

• Works with occupancy sensors

• Class 2 Output
