NOTES
*
All Parameters measured at Tc=25°C, nominal input voltage
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, and with constant line, load and ambient conditions.
(5)
The transient response is specified as the time required to settle
from 50 to 75% step load change (rise time of step = 2Sec.) to
a 1% error band.
(6)
Dynamic response is the peak overshoot voltage during the
transient response time defined in note 5 above.
(7)
The input ripple rejection is specified for DC to 120Hz ripple with
a modulation amplitude of 1% Vin.
(8)
For module protection only, also see note 2.
(9)
The logic shutdown pin is Open Collector TTL, CMOS, and relay
compatible. The input to this pin is referenced to input minus and
is protected to +100VDC.
(10) 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.
(11) The case thermal impedance is specified as the case temperature
rise over ambient per package watt dissipated.
