2.5 to 5 kW General Purpose Amplifiers
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 four-quadrant amplifier that offers up to 200 Ap power, DC to100 kHz small-signal bandwidth, and controlled-current or controlled-voltage modes of operation. The 7794 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.
7796HC
Power Amplifier
The 7796HC power amplifier offers up to 85 Ap continuous at 13.5 VDC, DC - 150 kHz small-signal bandwidth, and controlled-current or controlled-voltage modes of operation. The 7796HC can be used to simulate ripple noise, drop outs, surges and ground shift noise as required by a variety of standards for DC powered electronics in the aviation and automotive industries. With configurations capable of up to 600Ap and the ability to both source and sink, the 7796HC is your best solution for high-current DC Conducted Immunity testing.
