Test must be curried out with direct current.
 Isolation Resistance
Use DC isolation tester (MAX. 500V) to measure the isola-
tion resistance between output and baseplate. The isolation
resistance is more than 100MΩ at 500VDC. Note that some
isolation testers would make high voltage pulse occur when the
applied voltage is varied. Ensure the tester fully discharge after
the test.
Confirm the following items before you think the module is dam-
aged or failed.
1）No Output
2） High Output Voltage
Figure20-3 Withstand Voltage Test for Output - Baseplate
● Is the rated input voltage supplied?
● Is the remote sensing terminal connected correctly?
● Is the ON/OFF control terminal connected correctly?
● For adjusted output, is the variable resistance network
● Is there any trouble with the connected load?
● Is the remote sensing connected correctly?
● For adjusted output, is the variable resistance network

The performance of a system with Power Module is influenced
according to various conditions -- PCBs, chassis, mechanics,
heat dissipation. Please evaluate actual products, and confirm
its performance. (For details, please refer Power Module Appli-
cation Note.)
