and full rated load unless otherwise noted. Refer to the
CALEX Application Notes for the definition of terms,
measurement circuits and other information.
(2) Determine the correct fuse size by calculating the maximum DC
current drain at low line input, maximum load then adding 20 to
25 percent. Slow blow type recommended.
(3) No minimum load required.
(4) Short term stability is specified after a 30 minute warm-up at full
load.
(5) Transient response is defined as the time for the output to settle
from 100% step load change to a 1% error band (rise time of step
=2 µSec).
(6) Dynamic response is defined as the peak overshoot during a
transient as defined in note 5 above.
(7) The input ripple rejection is specified for DC to 120Hz ripple with
a modulation amplitude of 1% of Vin.
(8) For module protection only, with use of external fuse on input
circuit, see note 2.

A
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.
(10) The case thermal impedance is specified as the case temperature
rise over ambient per package watt dissipated.
