The Thomas Research Products SD3-33-120 is a tri-level dimming control module designed for use with 0-10V dimmable LED drivers. This module allows for quick switching between three levels of light output (33%, 66%, 100%) using standard wall switches, eliminating the need for an expensive dimmer unit.
Key electrical specifications include an input voltage range of 100-132 Vac at 50/60 Hz, with a maximum pass current of 1.0A at 120Vac input. The module supports a maximum LED driver power of 100W and has a maximum insertion loss of less than 1.5W. The Class 2 control output is 0-10V, operating in current sinking mode with a maximum of 50mA.
Environmentally, the SD3-33-120 can be stored between -40°C and +85°C and operates from -40°C to 75°C (max case temp). It has a lifetime of 1,000,000 switching cycles and operates within a humidity range of 5% to 95%. The module is designed for installation within the luminaire enclosure as required by UL standards. It is compatible with occupancy sensors and standard wallbox switches.
