3-8. Parallel Operation
(A) Operation to increase the Output Current is not possible.
(B) Operation as a Backup Power Supply is possible as follows.
1. Set the power supply output voltage higher by the amount of forward voltage drop ( V
F
) of the diode.
2. Please adjust the output voltage of each power supply to be the same.
3. Please use within the specifications for output voltage and output current.
