COVID-19 Update (May 21st) — While our offices remain closed to the general public, Musson has resumed selected operations in compliance with county guidelines. Non-contact pickup is available for customers who place their order online or by email with our sales/rentals team.
While most of our team continues to work remotely, select employees have their direct extension forward to their cell phone. If unavailable, you can leave a voicemail. In an emergency, please contact us at COVIDemail@example.com or by leaving a voicemail in our general mailbox, which is closely monitored.
Please note we will be closed from Friday, July 3rd through Sunday, July 5th to celebrate Independence Day. We'll re-open at 8:30 am on Monday.
The Advanced Features (AF) Dimmer Module are designed for use in Sensor+ and Sensor3 Series modular rack enclosures. Advanced Features Dimmer Modules enable dimmer-specific feedback of load circuit data while performing digital phase angle dimming in AF-capable Sensor+ dimmer enclosures. The high-density, dimmer modules feature modular installation and removal, fully magnetic circuit breakers and enhanced risetime toroidal filters.
Dual 15A/20A Dimmers, or Single 50A/100A Dimmer
Works great with most:
Incandescent lighting (0-100%)
Low voltage lighting (0-100%)
Cold Cathode lighting
2-wire Fluorescent ballast³
Load dropped below recorded value
Load increased over recorded value
DC on dimmer output
SCR failed on/off
Circuit breaker tripped
Dimmer module removed
Dimmer load absent
Withstand hot-patching of cold loads up to full rating
100,000A Short Circuit Current Rating
UL and cUL Listed for continuous duty at 100% of rated load
Only for compatible Sensor Racks, see datasheet for details. Not for Unison Racks.
All available spaces in a rack must be filled to ensure proper cooling. Use Air Flow modules to complete a rack when fewer than the maximum number of circuits are required. For example, a 6-module rack powering 8x 20A dimmers requires 4x D20 modules and 2x Air Flow modules.
¹ Risetime measured at full load, at worst case 90° firing angle, and from 10-90% of output wave form
² Sizing of Neon transformer used in dimming applications should be 1.5x greater than size used in non-dimming applications
³ Dimming range of 2-wire fluorescent ballast is dependent on lamp ballast combination. Contact ETC for range verification
