180/220 kW, high performance, all-digital dimming system consisting of up to six independent MEMORACK 30 modules, mounted on telescopic guides and easily disconnectable. These modules are self-contained 19" x 3U units, configured as 12 x 3 kW, 6 x 5 kW, or 3 x 12 kW. The MEMORACK 180 system is intended for professional applications in stage and studio lighting whenever individual plug-in modularity is not required. The dimmer modules can easily be removed and installed in touring racks. Available in several configurations:

Product Features
