COVID-19 Update (January 4th, 2021) — While our offices remain closed to the general public, Musson has resumed selected operations in compliance with county guidelines. Non-contact pickup remains available for customers who place their order online, by email, or by phone.
Most of our team continues to work remotely, and many employees are available through their direct extension. In an emergency, please contact us at COVIDfirstname.lastname@example.org or by leaving a voicemail in our general mailbox.
The Standard Dimmer Module is designed for use in all Unison/Sensor3 Series Racks. Standard Dimmer Modules provide cost-effective digital forward phase angle dimming for standard loads such as incandescent, low voltage, quartz, neon, cold-cathode and 2/4-wire fluorescent ballasts. The patented, high-density, dual modules feature modular installation and removal, fully magnetic circuit breakers and standard or enhanced risetime toroidal filters.
Dual 15A or 20A Dimmers
350μS or 500μS risetime¹
Works great with most:
Incandescent lighting (0-100%)
Low voltage lighting (0-100%)
Cold Cathode lighting
2-wire Fluorescent ballast³
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
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
