12 Watt Dual Series DC/DC Converters
Description
Features
!
These 10 and 12 Watt Dual Output DC/DC converters are
designed for telecommunications, medical or industrial
equipment and instrumentation systems. The converters
feature very wide input voltage ranges.
Low Noise Output
!
LC Type Input Filter
!
Six-Sided Shielded Steel Case
The converter consists of a hi-speed chopper circuit using
state of the art MOSFET technology, isolation transformer,
and high regulation linear post regulator. This provides for
very low noise and ultra stable output voltages.
!
Very Wide Input Voltage Ranges
(9-36, 18-54, and 24-72)
!
High Efficiency Operation
!
Long Term Output Fault Survival
!
5 Year Warranty

NOTES
(3) No minimum load required.
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.
*
(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 a 100% step load change to a 1% error band (rise time of
step = 2µSec).
(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.
(6) Dynamic response is defined as the peak overshoot during a
transient as defined in note 5 above.

(8) Thefunctionaltemperaturerangeisintendedtogiveanadditional
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

temperature range.
