Note:
(1) The PSU shall withstand overvoltage conditions up to a maximum AC input voltage from 264Vrms - 275Vrms at 47Hz -
63Hz for up to 10 seconds. The PSU should continue to operate normally in this period of time (+48V output remains).
(2) At room temp 25℃only.
Output Characteristics
The following parameters must be met at all operating conditions including all input frequencies (47Hz – 63Hz), voltages
(90VAC – 264VAC), and temperatures (-40°C, 25°C, and 85°C).
