Dear Colleagues. A happy new year to you all!
I have a problem with a well-known safety testing agency regarding an AC/DC "wall wart" type adapter. The adapter is fully approved to IEC/UL 60950-1 but in this case I am using it to power a product that is being evaluated to IEC/UL 60065. The agency has informed me that the adapter has failed approval due to the softening temperature of the insulating material supporting parts of the adapter as specified in clause 7.2 of IEC 60065. I thought there was an agreement that if a power supply met the requirements of IEC/UL 60950-1 it would be acceptable for use with products tested to IEC/UL 60065 provided it was used within its performance specification. Is this belief incorrect? Many thanks in advance. Ian McBurney Design & Compliance Engineer. Allen & Heath Ltd. Kernick Industrial Estate, Penryn, Cornwall. TR10 9LU.
