 Insulation Resistance
Use DC insulation tester (MAX 500V) between output
and baseplate. Insulation resistance value is 100MΩ and
above at 500VDC applied voltage. Also take note that de-
pending on the insulation tester used, some testers gener-
ate high voltage pulse. Discharge the power module after
test using a resistor, etc.
 Withstand Vibration
Refer to Application Notes “Mounting Method” section.
 Withstand Shock
Withstand shock value is defined to be the value at Den-
sei Lambda shipment and packaging conditions.
3） Output voltage is low
4） Load regulation and line regulation is large
5） Output ripple voltage is large
