 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.
Verify following items before concluding power module
damage.
1） No output voltage
2） Output voltage is high

 Withstand Shock
Withstand shock value is defined to be the value at Densei
Lambda shipment and packaging conditions.
 Others
The performance of a system with Power Module is in-
fluenced according to various conditions -- PCBs, chas-
sis, mechanics, heat dissipation. Please evaluate actual
products, and confirm its performance. (For details, please
refer Power Module Application Note.)
