ANALOG CONTROL

External Resistance Control of Power Output

Background External Resistance control of the power output is
accomplished using the analog control connector
on the rear panel. There are two external voltage
control ranges, 0 V to 5 V and 0 V to 10 V,
depending on the configuration.
For 0 V to 10 V:

Output power = full scale power x (external
voltage/10)
PIN 5 (VREF) will output 10V.

For 0 V to 5 V:
Output power = full scale power x (external
voltage/5)
PIN 5 (VREF) will output 5V.
