(2) for long term short circuit protection of the converters, install a slow blow fuse in the input circuit. choose a fuse size that is 125% of your applications actual input current and does not exceed 115% of the full load input current. (3) no minimum load required. (4) short term stability is specified after a 30 minute warm-up at full load, and with constant line, load and ambient conditions. (5) after a 100% step change of the load, the output voltage will bewithin 1% of the final value within the transient response time. (6) dynamic response is the peak overshoot voltage during the transient response time defined in note 5 above. (7) for module protection only, see also note 2. (8) the functional temperature range is intended to give an additional data point for use in evaluating this power supply. at the low functional temperature the power supply will function with no side effects, however, sustained operation at the high functional temperature will reduce expected operational life. the data sheet specifications are not guaranteed over the functional temperature range.
