Appendix C
Sensor+ SineWave Dimming
This appendix provides information for configuring a Sensor+ system that includes one or
more UL and cUL approved Sensor+ SineWave dimmer installation racks.
SineWave Benefits
Sine wave dimming provides “silent dimming” by controlling the power in a way that
maintains a clean sinusoidal wave form to your fixtures and does not create any “lamp
noise” or “buzz”. Due to the added level of control, ETC SineWave dimming also provides
superior voltage regulation.
Other sine wave benefits include:
• Saves energy compared with phase-controlled dimmers
• Reduces volt-drop which means less heat dissipation
• Improves lamp life – lower maintenance costs
• Harmonic distortion is virtually eliminated
• Reduces cost of electricity by removing reactive component (Unity Power Factor)
• Saves on infrastructure costs – reduced size of wiring and containment plus lower-
rated switch gear and transformers
• Accommodates generator supplies and poor mains
• Controls virtually all types of light source, even HMI
Configuration
SineWave (SW) racks are configured in the same way as SR racks. However, SW racks
only use D20SW dimmers. All other rack and dimmer properties are set in the same way
and coexist in your same rack configuration file.
• When adding a rack, select SW24 from the rack type list.
• When selecting module type, choose D20SW.
