DS C-544
14-BIT DIGITAL-T O-S Y NCHRO CONV ERT ER
HIGH EFFICIENCY: POWERED FROM
REFERENCE INPUT
DESCRIPTION
The
(D/S) converter compliments DDC’s
low profile DSC-644 industry stan-
dard by providing additional features.
The DSC-544 has a 0.82” high profile
and standard pinouts. The need for
+15 V and -15 V power supplies has
been eliminated. The unit is powered
from the reference input by an inter-
nal pulsating power supply, making it
very efficient. The reduced heat dis-
sipation has made it possible to
increase the load at 400 Hz by a fac-
tor of three, and the power output at
60 Hz is limited only by the size of the
internal power transformer.

digital-to-synchro
The DSC-544 also retains the many
improved features of the DSC-644.
The output is fully protected against
overloads, transients from load kick-
backs, short circuits and overheating.
An aluminum top plate in the module
improves thermal dissipation. In addi-
tion, the circuit design provides a
smoother, more accurate output with
improved transient response and neg-
ligible scale factor variation.
APPLICATIONS
The DSC-544 is the preferred D/S con-
verter when its special features are
required: elimination of external ±15 V
power supplies, elimination of an exter-
nal transformer at 60 Hz, greater drive
capability at 400 Hz, and less heat dis-
sipation. The converter can be used in
many applications where digitized shaft
angle data must be converted to syn-
chro form to drive control transformers,
control differential transmitters, and
angle indicators. Because these con-
verters are very rugged, and meet the
requirements of MIL-STD-202, they are
suitable for the most severe industrial
and military applications, including mili-
tary ground support and avionics. They
are very useful in computer-based sys-
tems where digital-to-synchro informa-
tion is used, such as simulators, flight
trainers, flight instrumentation, and fire
control systems.
