Hi Arthur,
We have a customer that has lost a few TP-VRHP-2456. His load is pretty lite at 15-20W.
I haven't been able to recreate the issue he is seeing in the lab, even at 70W load. He is powering from a 24VDC battery bank.
We rec'd two of the failed units back and both units have stress on the daughter board. One is totally burnt and the other is starting to be burnt. Both units are dead.
Can you advise what might be the issue that would cause this type of failure?
Thanks,
Scott
