In the series tracking mode, the maximum output voltage of 

both the “A” and “B” supplies can be simultaneously varied 
with one control. The maximum “B” supply voltage can be 
set to the same value of the “A” supply by using the “A” 
VOLTAGE control. 

The output voltage (across the two supplies) is actually 

double the Volt meter reading.  The actual output current 
would be the value read from the mA meter (since the two 
supplies are wired in series, current flowing through each 
supply must be equal). 

1. Set the power supplies to the TRACKING SERIES mode by 

setting the TRACKING/INDEPENDENT switch to the 
SERIES (left) position.

 

2. Set the A/B Metering switch to the A (up) position.

 

3. The “B” VOLTAGE AND CURRENT controls are 

disabled; turn both to their minimum positions.  The 
maximum current is set using the “A” CURRENT control.  
Follow the instructions for “Setting Current Limit” 
(INDEPENDENT USE OF “A” OR “B” SUPPLY section of 
this manual) using the “A” CURRENT control.

 

4. Adjust the output voltage to the desired level using the “A” 

VOLTAGE control (remember that the actual output voltage 
is double the reading on the Volt meter).

 

5. Turn off the power supply and the equipment to be powered 

during hook-up.

 

6. Connect the positive polarity of the device being powered to 

the red (+) terminal of the “A” power supply.

 

7. Connect the negative polarity of the device being powered 

to the black (-) terminal of the “B” power supply. 

 

8. Fig. 8 illustrates the grounding possibilities when the 

unit is used as a 0-to-48 \volt supply. 

a. If the negative polarity of the equipment or circuit 

being powered is also the chassis or common, it 
may be grounded to earth by connecting the black 
(-) terminal of the “B” supply to the green (GND) 
terminal as shown in Fig. 8A.
