1.

 

Power each unit up independently. In the Control Panel menu, 
scroll to the Parallel

 

Settings screen and press Enter. 

 

2.

 

Scroll to the Parallel

 

Mode setting and press Enter. Scroll and 

choose a parallel mode setting, then press Enter. One unit must 
be configured as a Master, and the remaining units must be set 
to Slave. If more than one unit is configured as a Master, the 
units will not operate in parallel correctly. 
 
Since the Slave units will be controlled by the Master, set the unit 
you would like to use to set the Output Voltage and Current Limit 
as the Master unit. You will be unable to set the Output Voltage 
or Current Limit from any of the Slave units once they are 
configured as Slaves. 

 

3.

 

Scroll to the Device ID setting and press Enter. Scroll and choose 
a unique device ID number for each unit, then press Enter. If 
more than one unit is assigned the same device ID number, the 
units will not operate in parallel correctly. 

 

NOTE:

 

Although not recommended, it is possible to connect up to six 

Digital  Series  power  supplies  in  parallel  without  using  the  Smart 
Parallel  feature.  It  is  important  that  the  parallel-connected  power 
supplies  generally  share  the  load  equally.    In  order  to  achieve  this, 
the  size  and  length  of  the  connecting  wires  should  be  sized 
appropriately  and of the same gauge, and the  wire  lengths  between 
the  power  supplies  should  be  virtually  identical.  To  ensure  proper 
load  balancing  without  using  the  Smart  Parallel  feature,  use  a 
voltmeter to independently measure the output voltage of each power 
supply  with  the  load  connected,  then  adjust  the  output  voltage  level 
of each power supply using the Intelligent Power Control interface on 
the front of the Digital Series power supply until the outputs are within 
+/- 1% of each other.  

 
 

4.3.  Connecting the Power Supplies in Parallel 

 

  

WARNING!

 

Do not use the Battery Backup/LVD option 

on 

units connected in parallel, as there is a risk that the potential 
load current could be higher than the rating of the internal low 
voltage disconnect relay.
