Appendix A - Analog Control Inputs
As a standard feature, PLS1500 power supplies have an analog port that allows remote control. The analog control option
allows the use of either 0 - 3 volt inputs, 0 - 5 volt inputs or 0 -10 volt inputs. In addition, there is a 3.0 volt reference source so
that external potentiometers can be used as inputs.
The pinout of the Analog control connector is as follows:
The connector physical pinout is shown below. The correct mating connector is an On Shore Technology Inc. 5 pin connector
such as their part number OSTTJ0531530.
To use a potentiometer as the control source connect one end of the potentiometer to the 3.0 Volt Reference, the other end to
Ground and the wiper to the control Input. The potentiometer should be in the range of 1K to 10K ohms. Set the power supply
to run from a 3 volt analog input on voltage or current or both.
