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 found in the
CALEX Power Conversion Design Guide & Catalog.
Measurement bandwidth is 0 - 20 MHz. See the applications
section of this note for more information. Input reflected ripple is
measured with a 3.3 to 33F, 0.5 to 5 ohm ESR, 100 Volt
aluminum electrolytic capacitor connected directly across the
input pins.
(3)
Refer to the CALEX Application Notes for information on fusing.
(4)
Optimum performance is obtained when this power supply is
operated within the minimum to maximum load specifications.
With other load currents the output voltage may be outside of the
specification limits.
Tests should be run for the specific
application.
(5)
Dual output regulation is specified by simultaneously changing
both ±12V or ±15V outputs from minimum to maximum load and
noting the change in each output.
(6)
Cross regulation is defined as the change in one output when
only one of the other outputs is changed from maximum to
minimum load.
(7)
Short term stability is specified after a 30 minute warm up at full
load, constant line, load and ambient conditions.
(8)
Transient response is defined as the time for the output to settle
from a 50 to 75% step load change to a 1% error band (rise time
of step = 2s).
(9)
Dynamic response is defined as the peak overshoot during a
transient as defined in note 8 above.
(10) A 1F 35V Tantalum capacitor is connected from each output
pin to the CMN pin, directly at the converter. Noise is measured
per CALEX application notes. Measurement bandwidth is 0 -
20MHz.
(11) 500 Watt peak pulse power transient suppression diodes used.
(12) 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. Sustained operation at the high functional
temperature will reduce the expected operational life. The data
sheet specifications are not guaranteed over the functional
temperature range.
(13) The case thermal impedance is specified as the case temperature
rise over ambient per package watt dissipated.
(14) Specifications subject to change without notice.
