AC1

2 Channels, 2-115 Vrms, 47 Hz-20 kHz (max. range), programmable

All Synchro, Resolver, LVDT, and RVDT measurement and simulation systems use transformers (either true transformers or galvanic solid-state transformers) whose main primary-to-secondary coupling is varied by physically changing (or, in simulation, commanding) the relative orientation of the two windings. For operation, the primary winding of these transformers is excited by an alternating current, and electromagnetic induction causes current to flow in the secondary winding. Windings are fixed at certain characteristic electrical angles to each other on the stator (e.g., a Synchro has three secondary winding legs, each at 120 E-degrees apart).

The module is used to provide an AC signal source when a secondary reference source other than the optional on-board reference module is required. The modules are programmable for full range voltage outputs from 2 to 115 VAC, and frequency from 47 Hz to 10 kHz.
