The AT402 is a wall mounted permanent install, four channel architectural dimmer rated a 2400 Watts per channel. This dimmer accepts DMX-512 control signals and simple local input contact closures. It is an ideal architectural dimmer for less complex environments where the DMX protocol needs to be utilized. It is especially well suited for churches, theaters and auditoriums, but works well in restaurants, meeting rooms or other environments requiring a few heavy-duty dimmers. The AT402 allows you to create many functionally diverse visual environments for any space. UL-508 compliant
