7796
7796
AE Techron
Industrial Amplifier for High Current/Low Impedance Operation
Over 200 Ap / up to 180 Vp, DC to 100 kHz, Three-Phase
- Stable when driving a wide range of resistive, inductive or capacitive loads
- Field-selectable controlled-voltage or controlled-current operation
- Can be switched between rail supply modes to optimize for various load impedances
- Protection circuits guard against over/under voltage, over current, over temperature, and circulating ground currents
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 and DO160.
Key Performance Capabilities:
- 30A continuous at 28V DC
- 200A in-rush current capability
- 150 kHz small signal bandwidth
- ±180V DC capable
- >35 V/µs slew rate
- Four-quadrant operation (source and sink)
