Control Transformer Synchro

Model / MPN: VCT23-4N3 | NSN: 5990-00-914-0838

A synchro consisting of a stator and rotor inductively coupled. The electrical output of the rotor is dependent upon both the position of the rotor and the electrical input to the stator from a transmitter synchro or a differential synchro. Does not include variable resistors, goniometers, or variable transformers.
