4­7. Series Operation
For series operation, either method (A) or (B) is possible.
Method (A) Method (B)
Note :In case of (A), please connect bypass diodes to prevent reverse voltage.
Please select a bypass diode with maximum forward current rating more than output load current.
And maximum reverse voltage must withstand each power supply output voltage.
4­8. 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 (VF) 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 power.
4.Please select a reverse current prevention diode with maximum forward current rating more than output
load current. And maximum reverse voltage must withstand each power supply output voltage.
(A) (B)
4­9. Isolation Test
Isolation resistance between Output ­ terminal is more than 100MΩ at 500VDC. For safety operation, voltage
setting of DC isolation tester must be done before the test. Ensure that the unit is fully discharged after the test.
■ Output ­ terminal : 500VDC More than 100M
