Deviation vs Load

Notes:

Note4: For repeat Hi-Pot testing, reduce the time and/or the test voltage

Note5: Refer to local safety regulations if input over-current protection is also required. Recommended fuse: slow blow type

Notes:

Note4: Operation below 10% load will not harm the converter, but specifications may not be met
