An enclosure containing one to twelve (occasionally twenty-four) dimmers. Portable versions usually do not have casters, as they are light enough to be carried by 1-2 persons. They can however, be built into a roadcase to allow for easier transport. Install versions are often wall-mounted with accessory brackets. Some are intended to be mounted in a rack to form a larger system.
Some popular dimmer packs include:
CD80 Portable Packs | Strand Lighting - A Philips Group Brand
The above falls into the category of shoebox dimmer, but is still a dimmer pack.
