6 Watt Dual Series DC/DC Converters
Description
Features
Ideal for industrial applications, these 6 Watt Dual Output
convertersaresuitableforuseintelecommunications,medical
and other systems that require floating outputs.
!
Low Profile Copper Case (0.375" High)
!
Six-Sided Shielded Case
!
Low Input/Output Noise Operation
These DC/DC converters operate at a fixed frequency that
is independent of line and load. The isolation transformer
provides700VDCisolationbetweeninputandoutputgrounds
allowing the outputs to be floated above or below the input
ground. Designed for maximum performance, each unit has
an LC input filter, high speed MOSFET power chopper and
short circuit protected linear post regulators.
!
700 VDC Input/Output Isolation
!
Short Circuit Protected Output
!
Fixed Frequency Operation Independent
of Line and Load
!
Highly Regulated/Low Drift Output
The copper case, measuring only 0.375" high, is shielded
on all six sides to minimize radiated noise. All converters in
this series are guaranteed under the CALEX 5 Year Warranty.
!
Rugged High Speed MOSFET Power Chopper

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.
(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 percent.
*
(4) No minimum load required.
(2) Turn on time is defined as the time from the application of power
until the output is within 1% of its final value.
(5) Short term stability is specified after a 30 minute warm-up at full
load and with constant line, load and ambient conditions.

(6) The transient response is specified as the time required for the
output to settle from a 100% step load change (Rise time of step
= 2 µSec.) to a 1% error band.
Seal around terminals is not hermetic. Do not immerse units in any
liquid.
(7) Dynamic response is the peak overshoot voltage during the
transient response time as defined in note 6 above.
