AC3
2 Channels, 28-115 Vrms, 47 Hz-2.5 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.
- Voltage Output: 28 Vrms to 115 Vrms, programmable with a resolution of 0.1 V 28.0 to 115.0 Vrms or 47 Hz to 2.5 kHz frequency range
- Accuracy (No Load): ±3% of setting < 15 kHz, ±6% of setting ≥ 15 kHz
- Regulation: ±5% (No Load to Full Load)
- Output Drive: 6 VA maximum
- Output Protection: Overcurrent / (10x automatic retry; @ 1.3 sec intervals; after 10 tries, shutdown with manual reset)
- Frequency: 47 Hz to 2.5 kHz, programmable with 0.1 Hz steps
- Frequency Accuracy: ±0.1% of programmed frequency or ±1 Hz (whichever is greater)
- THD: 3% (maximum)
- Power: 5 VDC @ 350 mA, ±12 VDC @ 230 mA (Quiescent, no load); Note: Add ±12 VDC @ 100 mA for every 1 VA Load.
- Ground: Isolated from system ground.
- Weight: 1 oz. (28 g)
- : Note: This function module uses a mechanical relay for switching between output ranges (may not be suitable for some embedded applications).
