Product Description
The RD-121 is a 14,400 Watt, 12 channel, rack mountable lighting dimmer. Each of the channels has a capacity of 1200 Watts. It is controlled via low voltage signals which may be LMX-128 (3 wire multiplex), or USITT DMX-512. The unit is fan cooled. Channels may be independently assigned from the unit. The unit is over temperature and over voltage protected and has a magnetic circuit breaker for each channel. There are several options for channel output connection panels. Options include: Edison plug, Knockout panel with internal terminal strip, External Terminal Strip, Patch panel, Stage pin panel, and Socapex Connector panel. The RD-121 also has several "stand alone functions" which enable it to operate without a control console. These functions include a storable scene which may be activated by an external switch closure, a programmable chaser, and 7 factory set chase patterns.
