Short term stability is specified after a 30 minute warm-up at full
load, and with constant line, load and ambient conditions.
The transient response is specified as the time required to settle
from 50 to 75% step load change (rise time of step = 2μ Sec.) to
a 50 mV error band.
Dynamic response is the peak overshoot voltage during the
transient response time defined in note 7 above.
The input ripple rejection is specified for DC to 120Hz ripple with
a modulation amplitude of 1% Vin.
(10) For module protection only, see also note 4.
(11) The logic shutdown pin is Open Collector TTL, CMOS, and relay
compatible. The input to this pin is referenced to Pin 2, -Input
and is protected to +100 VDC.
(12) Case is tied to Pin 3, +Input.
(13) 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.
(14) The case thermal impedance is specified as the case temperature
rise over ambient per package watt dissipated.

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.
Noise is measured per CALEX Application Notes.
An external capacitor capable of withstanding at least 700 mA RMS
of 120 kHz ripple current must be connected directly across the +
and - inputs. Suggested capacitors are:
Sprague Electric:
672D686H100DM3C, 68μF, 100V
672D127H100ET3C, 120μF, 100V
Panasonic:
ECEA2AFE101, 100μF, 100V
ECEA2AFE121, 120μF, 100V
United Chemi-Con:
SXE100VB120M12.5X25LL, 120μF, 100V
SXE100VB180M12.5X30LL, 180μF, 100V
SXE100VB220M12.5X35LL, 220μF, 100V
Note:All of the above capacitors are 105
°
C Rated. Multiple smaller sized
capacitors may be used in parallel as long as their total ripple
capability is above 700 mA RMS (see IRR curve).
(4)
Determine the correct fuse size by calculating the maximum DC
current drain at low line input, maximum load and then adding 20
to 25%. A slow blow type fuse is recommended.
(5)
No minimum load required.
