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.
