  Advanced Operation 

 

4-1 Series/Parallel Operation 

Output voltage or output current of the RE power supply units can be increased by 

connecting the output of the same model in series or parallel. 

 

4-1-1 Series Operation 

Connect units of identical rated output voltage and current 

As per diagram right. 

The maximum output voltage is 250 V in total. Please do not 
carry out series connection exceeding 250 V. 
 

 
    4-1-2 Parallel Operation 

Connect units of identical rated output voltage and current 

as per diagram right. The same voltage should  be set for all. 

Output current is the total of the individual  current. 

Set the OVP level of all power supply units to maximum to avoid 
damage. 

 

4-2 Divided Operation 

Connect as shown on the right. 

When used in this way, the remote connector is connected to the 
-output.    Do not connect together with any other remote connector.
