Notes:
-
After each of above tests, EUT can pass the dielectric strength test which specified in clause 10.3.
-
Limits for each winding (class B): 175-10-45=120K; plastic/metal enclosure: 65K.
-
All the components damaged test as above, fault repeated two more times and the results were same.
Supplementary information: o-c=opened circuit; s-c=short circuit; o-l=over load.
Supplementary information: o-c=opened circuit; s-c=short circuit; o-l=over load.
-
* Only power board with 100-120VAC input have component VR1.
