4. Isolation / Withstand Voltage
4-1. Isolation Test
Isolation resistance between output and FG (chassis) shall be more than 100MΩ 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.
4-2. Withstand Voltage
This series is designed to withstand 3.0kVAC between input and output, 1.5kVAC between input and FG (chassis) and
500VAC between output and FG (chassis) each for 1 minute. When testing withstand voltage, set current limit of with-
stand voltage test equipment at 20mA ( Output-FG (chassis) : 100mA ). 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 at timer switch on and off. Connect input and output as follows :
(a) Input ~ FG (chassis) : solid line
(b) Input ~ Output : dotted line
1.5kVAC, 1min (20mA)
3kVAC, 1min ( 20mA )
(a) Output ~ FG (chassis) : 500VDC, 100MΩ or more
