1. Product
overview
The Chroma-Q Magic Box PS12 supplies power and data to the Chroma-Q range of colour
changers and compatible products (see below). A maximum capacity of 12PU (Power Units), it
can be controlled remotely via ANSI E1.11 USITT DMX 512-A and delivers power and data via 3
XLR4 outputs.
2. Operation
Power
Connect power through a fused male IEC chassis connector with input power of 100 - 240V, 50-
60 Hz. The standard fuse is a 5x20mm 6A GMA 125V. It provides 3 circuits of 24VDC.
Data
Data input ANSI E1.11 USITT DMX 512-A from an external source or lighting control console
connects through a male XLR-5. A pass through connection is available on the female XLR-5.
Power and data outputs are from 3 individual female XLR-4 outputs to the colour changer units.
Termination
Data termination is built in at the input.
Indicators
The red LED indicates mains power is present and the green LED indicates a DMX signal is
present.
System Diagram
The PS12 has been designed for cable loops of up to 60m/200ft per output. Closing the loop
with a return cable will enhance the stability of the power delivered and connected to your data
line.
Load
To simplify the choice of power supply we use the "PU" (Power Unit) to calculate the load
requirements of the Chroma-Q system. The PS12 will supply up to 12 PU's, so you can plug-in
12 Chroma-Q Plus (12 x 1PU = 12PU). The individual output has a maximum capacity of 8PU.
