5. Isolation / Withstand Voltage
5-1. Isolation Test
Isolation resistance between output and
of DC isolation tester must be done before the test. Ensure that the unit is fully discharged after the test.
(a) Output ~
(chassis) : 500VDC, 100M or more
5-2. Withstand Voltage
This series is designed to withstand 4.25kVDC between input and output, 2.25kVDC between input and
and 500VDC between output and
withstand voltage test equipment at 20mA ( Output -
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 ~
(chassis) : solid line
2.25kVDC, 1min (20mA)
(b) Input ~ Output : dotted line
4.25kVDC, 1min ( 20mA )
(chassis) shall be more than 100M at 500VDC. For safety, voltage setting
(chassis) each for 1 minute. When testing withstand voltage, set current limit of
(chassis) : 100mA ). The applied voltage must be gradually
