Two Identical Negative Voltages With a Common Positive (Refer To Fig. 13)

When the same negative voltage is required at two points in the same circuit and a common positive is needed, perform the following:

1.Select the TRACKING PARALLEL operating mode and set the A/B Metering switch to monitor the “A” supply.

2.Set the desired voltage and maximum current using the “A” VOLTAGE and CURRENT controls.

3.Connect a ground wire between the “A” supply positive terminal and the GND (green) terminal.

4.Turn off the power supply and the equipment to be powered during hook-up.

5.Connect the negative polarity inputs of the circuit to be powered to the negative (black) terminals of the supplies. Connect the common positive input of the circuit to be powered to the “A” supply’s positive (red) or GND (green) terminal.
