Withstand Voltage - TDK-Lambda DBM20 Instruction Manual

PA640-04-01B
4-14. Isolation Test
Isolation resistance between input/output & signal
ports to shall be more than 100M at 500VDC. For
safety purposes, voltage setting on DC isolation tester
must be done before the test. Ensure that the unit is
fully discharged after the test.

4-15. Withstand Voltage

This model is designed to withstand 500VAC between
input/output & signal ports to
When testing withstands voltage, set current limit of
withstand voltage test equipment at 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 buffer module may be
damaged by high impulse voltage at timer switch on
and off. Connect input/output & signal ports as
follows :
