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.
