3-phase ac power source, alternator simulator imitates aircraft power busses

HIGHLAND TECHNOLOGY P900 3-phase ac power source and alternator simulator can simulate aircraft power busses and PMA permanent-magnet alternators and drive FADEC shunt regulators. Each phase can output 0 to 160VRMS at 200VA and 120Hz to 4kHz, including applications requiring a 400Hz or APU/wild power source. Outputs can be programmed as low-impedance voltage busses or alternators with controlled source impedances.  Features include output measurements, waveform monitors, and fault simulation. Control interfaces are USB and Ethernet. Product is packaged in a 3U aluminum rackmount enclosure and operates from single-phase ac power.
