DSC-544 Datasheet | DDC

DESCRIPTION The DSC-544 digital-to-synchro (D/S) converter pliments DDC’s low profile DSC-644 industry standard 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 internal pulsating power supply, making it very efficient. The reduced heat dissipation has made it possible to increase the load at 400 Hz by a factor of three, and the power output at 60 Hz is limited only by the size of the internal power transformer. The DSC-544 also retains the many improved features of the DSC-644. The output is fully protected against overloads, transients from load kickbacks, short circuits and overheating. An aluminum top plate in the module improves thermal dissipation. In addition, the circuit design provides a smoother, more accurate output with improved transient response and negligible scale factor variation. APPLICATIONS The DSC-544 is the preferred D/S converter when its special features are required: elimination of external ±15 V power supplies, elimination of an external transformer at 60 Hz, greater drive capability at 400 Hz, and less heat dissipation. The converter can be used in many applications where digitized shaft angle data must be converted to synchro form to drive control transformers, control differential transmitters, and angle indicators. Because these converters are very rugged, and meet the requirements of MIL-STD-202, they are suitable for the most severe industrial and military applications, including military ground support and avionics. They are very useful in puter-based systems where digital-to-synchro information is used, such as simulators, flight trainers, flight instrumentation, and fire control systems.
