My customer is having difficulties with the surge testing and I’d like to ask your advices.
They are using AMC1200 for the surge test, ±10KV (between L-FG) .
AMC1200 passed the test with 4KV, but with 10KV, the packaged damaged and experienced failure.
So, the customer is now wondering if using AMC1200B would be an option.
AMC1200B has 250V better surge immunity. Would it be an effective solution for the above-mentioned surge test?
If there are any other measures against surge, I’d appreciate it.
