2) For fuse opened condition, same result came out for each source of fuse.
3) For RF opened condition (fuse not provided), all tests have been repeated ten times to show the
reliability of the test results.
4) All sources of photo coupler are submitted to stress relief test at 150°C air-circulating oven, after the
test, these samples withstood the AC 3000V electric strength test.
