Electric Strength Test

Primary circuit to secondary circuit electric strength testing was completed according to IEC61347-1

and IEC61347-2-13.

Input and output was shorted respectively. 3750VAC/50Hz sine wave applied between input and output

for 1min, and operation was verified.

Surge Test

Line to Line 3000V surge testing was completed.

Input voltage was set at 230VAC/50Hz. Output was loaded at full load and operation was verified

following each surge event.
