Solid State Synchro Control Transformer and Solid State Resolver Control Transformer
SCT-RCT Series
Computer Conversions Corporation
The SCT Series are low cost, miniature, solid state control transformers designed for military and industrial control applications. They will directly replace conventional electromechanical control transformers & thus provide digital control to existing analog servo systems. They simultaneously accept a 3 wire synchro input (0) and a digital angle input (0), and provide an ouput which is the sine of the difference between these two input angles (A sin wt sin (0-0) ("wt" is the synchro excitation frequency).
