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 Constant Current Module is a dual, plug-in assembly for use in all Unison/Sensor3 Series Racks. The Constant Current module distributes power with overcurrent protection from the dimmer rack enclosure to non-dimmed loads, typically motors, backup and emergency systems or auxiliary power distribution panels.
Dual 15A or 20A Circuits
Always on, does not respond to control signals (see the Relay Module for on/off control)
Works great with:
Backup and Emergency systems
Auxiliary power distribution panels
Replaceable fuse for short circuit protection and fault current coordination
100,000A Short Circuit Current Rating
UL and cUL Listed for continuous duty at 100% of rated load
While this module can power LEDs and intelligent lights, we don't recommend it since your fixtures will always be on. This will likely lead to a shortened fixture life, and more frequent service calls.
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.
Unlike standard dimmer/relay modules, no hot-patching of cold loads. Make sure to turn off the module circuit breakers before removing/inserting.
