the voltage of your controller and application requirements, the value of the
resistor will vary, but is typically in the 0.1Ω to 1Ω range. Contact the factory for
additional support.
When in ITE mode, the current will not be limited, and an error will be generated
and the output turned off if operating outside the allowable range.
The graphs below illustrate the minimum voltage requirements for the standard
5400-15-28, 5400-30-28, and 5400-20-56 TECSource controllers. Custom
configurations will have a different profile.
