Dove Systems DM424-RM Rack Mount Dimmer, 4 Channels 20A per Channel, in 2U Enclosure

Overview

The Rack-Mount DimmerMaster Dimmers are standard 19-inch, 2U rack units with 4 or 8 1200W dimmers in the 412 and 812 respectively and 2 or 4 2400W dimmers in the 224 and 424. The 224 and 412 draw no more than 40 Amps; they may be powered from a single 120VAC circuit. The 424 and 812 draw no more than 80 Amps and may be supplied by two 120VAC circuits. By request when ordering, they may be configured for 240V input for use with 240V lamps.

The unit accepts both DMX-512 and 0 to +10VDC control signals. The unit will let the higher of the two inputs (highest takes precedence, HTP) set the output level per channel. The starting DMX channel is set on the front panel’s thumbwheel switch, which also provides load testing and local control. A status LED indicates the presence of a DMX signal. With both male and female XLR connectors, the control signal may be daisy-chained from unit to unit. Alternatively, the control signals may be daisy-chained using internal screw terminals. The DMX signal may be terminated at the last unit by means of an internal DIP switch. Other internal switches set individual outputs for non-dim operation or force all outputs to full-on. There is also a Force On switch on the front panel.

Note: The -RMF has 5-pin XLR connectors on the front panel for In and Out. The -RMB has 5-pin XLR connectors on the back panel for In and Out. Finally, the -RMT has no XLR connectors and the user/installer may connect the DMX cabling directly to the internal terminal blocks through the back panel.
