The AE Techron 7224 is a DC-enabled power amplifier engineered for high-demand test, measurement, and research applications. Operating in user-selectable controlled-voltage or controlled-current modes, it delivers 900 W RMS continuous (up to 40 kHz) and 1,100 W RMS at 4 ohms, with peak currents reaching 52 A into 0.5 ohm loads over 40 mSec pulses. Multiple units interconnect to exceed 3,600 W or 200 A system output.
