6-10. Isolation Test
Isolation resistance between Output and
is more than 100M
Ω
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.
6-11. Withstand Voltage Test
These products are designed to withstand 4.0kVAC between input and output, 2.0kVAC between input and
and 1.5kVAC between output
and
for 1 minute. When testing withstand voltage, set current limit of the withstand voltage test equipment to 20mA. The applied voltage
must be gradually increased from zero to the testing value and then gradually decreased for shut down. When timer is used, the power supply
may be damaged by high impulse voltage at timer switch on and off. Connect input and output as follows.
Input – Output (Dashed line): 4kVAC, 1 minute (20mA)
Input –
(Solid line) : 2kVAC,1 minute (20mA)
Output –
: 1.5kVAC 1 minute (20mA)
