7548

Power Amplifier

The 7548 is is a 4-quadrant, high-powered unit designed to provide very low noise and fast slew rates. it can operate in either voltage or current mode and features a DC to 100 kHz small-signal bandwidth and a power range of over 3300 watts RMS. A single 7548 has an output capability of 100 Ap and 200 Vp. It can output a 40 mSec pulse with up to 105 Ap current into a 1- ohm load. If more current is needed, amplifiers can be combined in series or parallel and operate as a single system.

7794

Power Amplifier

The 7794 is a powerful fourquadrant amplifier that offers up to 200 Ap power, DC to100 kHz small-signal bandwidth, and controlled-current or controlled-voltage modes of operation. The 7796 works best into loads of 0.5 ohms or less. For greater voltage or current (up to 800 Ap) units can be combined in parallel or series. The 7794 is typically used when large currents are needed to drive very low impedances for long periods of time.

7796

Power Amplifier

The 7796 power amplifier offers up to 200 Ap power, DC - 100 kHz bandwidth, and controlled-current or controlled-voltage modes of operation. The 7796 works best into loads of 2 ohms or less. For greater voltage or current (up to 800 Ap) units can be combined in parallel or series. Typically used as a gradient amplifier in small bore, high gain MRI systems of up to 200 Ap per axis and to reproduce waveforms found in EMC standards like MIL STD 1275, MIL STD 461, DO160, and ATIS-0600315.2007.
