Connection in series 

 

 

Figure 9 

Connection of multiple units in series 

 
The series connection allows increasing the total output voltage. Connect the output terminals of each device in series checking 
the right polarity. 
 

Note 1: 

Before any power ON be sure to have connected the 

antiparallel diodes

 to all units. The voltage rating of EACH 

diode should cover the TOTAL voltage of the SERIES system. A diode as P600J is suitable for most applications.        

 

Note 2: 

Only  SMPS  of  the  same  model  (

same  rated  output  voltage

)  can  be  connected  in  series. 

Do  not  exceed  >  4 

units connected in series and > 200Vdc total voltage. For other situations contact the factory.  

Note 3: 

To  achieve  the  best  power  sharing  between  the  series  connected  devices  it  is  recommended  to  regulate  the 
output voltage of each device at the same value with a tolerance of maximum 0.1V. 

Note 4: 

When  using  several  devices  in  series  the  operating  mode  must  be  set  to  OVERBOOST,  using  CONSTANT 
CURRENT mode can result in instabilities in case of load short circuit. The maximum current setpoint shall be the 
same on every connected device. 

:  
 

When  the  units  are  used  in  series  do  not  connect  anything  to  the  auxiliary  connector  SENSE+/SENSE-  and 
SHARE+/SHARE-. Any connection to these signals may damage the units and the connected load.
