Start up is normally with load current not greater than 0.2 A. Start up with no load, or less than 0.2-A load, may make output
voltage higher and can be as high as 88 V. Start up with load current greater than 0.2 A may trigger over current protection and
may make output voltage in hiccup operation.
voltage higher and can be as high as 88 V. Start up with load current greater than 0.2 A may trigger over current protection and
may make output voltage in hiccup operation.
(2)
Load step down to zero may make output voltage higher and can be as high as 90 V.
