The evaluation board EVAL-M1-IM818-A is general power demonstration platform with CIPOS™ Maxi IPM IM818
series. And focus on 380 V
different IPM. For end user, it is only default for IM818-MCC. Other IPMs can be directly compatible and replaced
(Warning). But don't guarantee hardware change.
Warning:
EVAL-M1-IM818-A is only default for IM818-MCC, any hardware change will not be guaranteed.
All operations can be done only when the evaluation boards has been move away from the power for over
5 minutes and double check those all capacitance voltage are lower than 5V.
Operation only for those licensed professionals under qualified safety protection （including: person，
equipment, ESD）.
For any re-install, it is necessary to clean the thermal conductive silicone grease and coating it again.

Test results for output ability
In order to test the total power capability of EVAL-M1-IM818-A, the IPM case temperature is tested with different
input and output currents.
