Channel Control   
 
External channel control is used with the Channel 
Control connectors. Each channel control 
connector can activate each load, monitor voltage 
and current and has an external voltage reference 
input. The voltage and current monitors output 
0~100% of the rated current/voltage as a voltage of 
0~10V.

External Voltage 
Reference 
A voltage reference of 0-10V is used to represent 0-
100% of the rating voltage/current of a load 
module. As seen below the external voltage 
reference and the rating voltage/current have a 
linear relationship. By varying the reference 
voltage between 0~10V the voltage/current setting 
will be changed accordingly.
