E.  If "single supply" operation is desired, this allows the power supply to be used as twice the voltage and 

rating current simply by using the negative (black) terminal of    the SLAVE supply and the positive (red) 

terminal of    the MASTER supply, the configuration as shown in Fig.5-3. 

 

Fig.5-3 Single Supply 

 

If the chassis or common of the equipment being powered is separate from both positive and negative 

polarity power inputs. The output of the SLAVE (negative) supply is tracking the output of the MASTER 

(positive) supply. The configuration is shown in Fig.5-4.

5-4-3. Parallel Tracking Operation 

In the parallel tracking mode of operation, both supplies are strapped together (in parallel). This allows for a 

rating voltage supply with a double rating current capability. Only the MASTER output terminals are used for 

parallel tracking operation. In the parallel tracking mode, the SLAVE supply output voltage and current are 

tracking the MASTER supply output voltage and current. 

A.  Set the power supplies to the TRACKING PARALLEL mode by engaging both TRACKING switches. 

B.  Because both voltage and current of the SLAVE supply track the MASTER supply, the maximum current 

and voltage are set using the MASTER controls. Using the MASTER supply output jacks, follow the 

instructions  for "Setting Current Limit" (5-2 Section). Remember that the actual current output at the 

MATER supply output jack is double the reading on the SLAVE indicator meter.. Then push the output 

on/off key to enter voltage and current setting. 

C.  Adjust the output voltage to the desired level using the MASTER VOLTAGE controls. 

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

E.  Connect the positive polarity of the device being powered to the red (+) terminal of the MASTER power 

supply.
