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)
Noise is measured per CALEX Application Notes. The output
noise is measured with a 0.1F, 50V, ceramic capacitor connected
directly across the output pins. Measurement bandwidth is 0-20
MHz.
(3)
Determine the correct fuse size by calculating the maximum DC
current drain at low line input, maximum load and then adding 20
to 25% to get the desired fuse size. A slow blow type fuse
is recommended.
(4)
No minimum load required.
(5)
Short term stability is specified after a 30 minute warm-up at full
load, constant line and recording the drift over a 24 hour period.
(6)
The transient response is specified as the time required to settle
from a 50 to 75 % step load change (rise time of step = 2 Sec)
to a 1% error band.
(7)
Dynamic response is the peak overshoot during a transient
as defined in note 6 above.
(8)
The input ripple rejection is specified for DC to 120 Hz ripple with
a modulation amplitude of 1% of Vin.
(9)
For module protection only, see also note 3.
(10) Case is tied to Pin 5, CMN.
(11) 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.
(12) The case thermal impedance is specified as the case temperature
rise over ambient per package watt dissipated.
(13) These products are UL Recognized for an input voltage range of
36 to 60 VDC.
