9205/9305 Switch-Mode Amplifiers

9205/9305

9205/9305 amplifiers are a great choice when available AC Mains power is limited or may change. The 9205/9305 amplifiers couple an 85% operating efficiency with a universal, 100V-to-250V power supply with PFC (power factor correction). This highly efficient supply can draw up to 30% more power from a given-size AC Mains breaker while putting less noise back on the AC mains.

Combined, these features permit a 9205/9305 amplifier to produce up to 2 kW output when connected to a 20A, 120V mains supply and up to 5 kW from 230V or 240V sources. Plus, they can move seamlessly from lab to factory since they can be powered from any normal, single-phase, AC Mains supply. With a slew rate of up to 150 V/µs and a minimum drop/rise time of 7µs, 9205/9305 amplifiers are fast enough to meet the surge and dropout requirements of many current EMC test standards.

9205/9305 amplifiers are two- and three-channel versions, with all channels drawing power from the amplifier’s common power supply. This design allows power to shift dynamically between channels during operation, so up to 4500 watts of the power supply’s potential 5000 watts can be available at any given moment for use by any single channel. This dynamic power capability makes the 9205/9305 amplifier able to perform like a much more powerful amplifier, making it well-suited for applications that have intermittent power demands for each channel over time, such as MRI systems, multi-channel positioning systems, or multi-element sonar.

Low THD+N and IMD distortion and low DC drift make 9205/9305 amplifiers ideal for many industrial multi-channel applications. Because the 9205/9305 amplifier’s output is ground-referenced, channels can be used independently to create a three-phase, wide-bandwidth voltage source, or channels can be connected in series to form a higher-voltage differential output.

Altogether, 9205/9305 amplifiers are a great solution for a wide range of high-current, low-voltage, low-noise applications that require wide bandwidth and the ability to drive reactive or widely varying load impedances.
