ACS Rack
In a DMX512 controlled system the ACS rack is a power/data distribution unit for Series
200 luminaires only. The ACS rack connects to a DMX512 control console via a
DMX200 interface
ACS rack functions:
+ Receives 3-phase AC input power from a house service or modular rack via Cam-
Lok to Cam-Lok pigtails. (A 200A AC disconnect should always be used in-line
prior to the equipment.)
+ Provides AC power to the console.
+ Distributes data and power to the luminaires via Repeater Boxes. (Up to seven
repeaters may be connected via Series 200 trunk cables.)
There are two models of ACS racks: the standard ACS rack and ACS rack with backup.
The ACS rack with backup has the same features as the standard rack, but has three
powered output channels on the rack input panel to provide power for low current
devices such as the VLD, UDM or SPC-36 controller.
Note: In DMX512 controlled systems, only VL2C and VL4 luminaires may be controlled through the ACS rack.
In addition, the ACS rack with backup contains a complete backup set of signal processing cards. These backup
units are easily connected via a free-hang connector panel located behind the input panel access door.
