7-1. Isolation Resistance Test
Isolation resistance between output and earth shall 100M

at 500VDC. For safety, voltage setting of DC isolation
tester must be done before the test. Ensure that the unit is fully discharged after the test.

-2. Withstand Voltage
This series is designed to withstand 3kVAC between input and output, 2kVAC between input and earth for one
minute. When testing withstand voltage, set current limit of withstand voltage test equipment at 10mA. The applied
voltage must be gradually increased from zero to testing value and then gradually decreased for shut down. When
timer is used, the power supply may be damaged by high impulse voltage during timer switch on and off.
Connect input and output as follows :
Input - Output : 3kVAC, 1min (10mA)
Input - Earth: 2kVAC, 1min (10mA)
