6-11. 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 100MΩ
6-12. Withstand Voltage
This series is designed to withstand 4.0kVAC between input and output, 2.0kVAC between input and
terminal, and 1.5kVAC between output and terminal each for 1 minute. When testing withstand voltage, set
current limit of the withstand voltage test equipment to 10mA (output - terminal : 20mA). The withstand
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 might be damaged by high impulse voltage at timer switch on
and off. Connect input and output as follows.
■ Input – Output (Dashed line) : 4.0kVAC, 1min (10mA) ■ Output – terminal : 1.5kVAC, 1min (20mA)
Input – terminal (Solid line) : 2.0kVAC, 1min (10mA)
