LINE 10: Assigns the I/O pathname to the power supply.

LINE 20,30: Enter the operating voltage and current limit point.

LINE 40: Sets C equal to one half of the current limit point.

LINE 50-70: Determines the voltage setting for output 2. It is 20.2 V when the operating voltage is greater than 7 V, 7.07 V when the operating voltage is between 7 V and 2.5 V, and the same as the operating voltage below 2.5 V.

LINE 80: Clears the supply, sets the current of output 1 to one half of the current limit point, and sets the voltage of output 1 to the operating voltage.

LINE 90: Sets the current of output 2 to one half of the current limit point and sets the voltage of output 2 to the value determined by the operating voltage.

LINE 100: Waits 1 second before reading back output voltage and current.

LINE 110-160: Reads the output voltage of output 1 and the output current of outputs 1 and 2.

LINE 170: Prints the output voltage of the parallel outputs on the screen.

LINE 180: Prints the total output current of the parallel outputs on the screen. Note that this is the sum of the output currents of outputs 1 and 2.

Programming Outputs Connected In Series

To program outputs connected in series, you must first determine the maximum voltage and current that you would like to have available to your load. These values are the desired voltage limit and current limit points. Next, program the current of both outputs to this desired current limit point. The voltage of each output can then be programmed so that the sum of the voltages equals the desired voltage limit point. An easy way to do this is to set each output to one half of the desired limit point. Refer to Chapter 4 for more information on series operation. Figures 4-13 and 4-14 are examples of series configurations which apply to both the CV and CC operating modes. Note the sense lead connections shown in Figure 4-14.

The following example programs outputs 1 and 2 which are connected in a series configuration.
