ACS550 45A Power Card getting damaged again & again.
ACS550 45A, Power Card getting damaged again & again. Once in two months. Card gets damaged in running condition. It has happened twice in one month. ABB dealers comes & just replaces the power card as it is under warranty. No specific conclusion is drawn as to what the problem is. Please let me know if anybody faced a similar problem and how it can be sorted out permanently and the reason why this is happening.

Hi
you do not give any indication on the installation: humidity, temperature, other pollutants. The protection of the electrical box where is located the drive what degree of protection does it have?
Are there any filters to protect the air exchange? One short description of the application?
Are there any other inverters mounted in the same electrical box and nobody has had any problems?
I installed hundreds of ACS550s and those who had problems have had them due to external agents, typically due to the bad conditions in which they were installed, environmental causes prevailing, such as humidity to dustiness. Sometimes the causes were electrical, very unstable and unbalanced supply networks.
I do not want to say that this is your case, but I would point out that more than 5 million pieces were produced of ACS550 .... if it was not a robust and reliable drive, it would not have been so successful.
Could you try to indicate better the operating conditions and above all, what did the ABB service tell you when they have changed the broken unit?
Let us know about the the results of these faults are
