High Accuracy AC Reference Source
515
-
Clarke-Hess Communications Research
The Model 515 High Accuracy AC Reference Generator fills a need for a relatively low cost and practical solution for supplying a reference excitation to typical LVDT and Synchro/Resolver transducers. The Model 515 has built-in load sensing which, in effect, yields "zero" output impedance and virtually eliminates the effects of fluctuating output loads. With up to 15 VA of output into loads with as much as 80 of phase shift, the Model 515 is ideally suited to driving inductive loads.

Computer Conversions Corporation
This series of units were designed to satisfy Hi speed synchro/resolver applications where the output data must be fresh and no data staleness can be tolerated. The tranducers utilized are the same as in the regular MDS series, however different tracking electronics are used. The resultant data tracks the input shaft perfectly and is always fresh and accurate at input speeds up to 64 revolutions per second, depending on the resolution. Data in BCD or Binary formats are available, and clean, unambiguous crossovers are guaranteed.

DSx
Digital / Synchro Converter
Synchros are transformer-type voltage/current transducers that convert a shaft or other rotating device's angular position and/or velocity to a multi-wire AC electrical signal. Both deliver signals proportional to the Sine and/or Cosine of the shaft angle. A Digital-to-Synchro simulator is used to convert digital angle/velocity commands to corresponding Synchro/Resolver AC signals.
