The Model 7796 is our new top-of-the-line precision linear amplifier; it combines everything we have learned in over 40 years of building high power linear amplifiers.

The AE Techron 7796 Amplifier is a high powered unit designed to provide clean, reliable power for gradient coils in magnetic resonance imaging systems or in applications that require both significant short term (burst) and long term (continuous) power. A single 7796 has an output capability of over 210 amperes peak at its rated voltage. If more power is needed, up to four amplifiers can be combined in series or parallel and operate as a single system. The 7796 operates in either voltage or current mode and features DC-coupling, robust output devices and a power range of over 6600 watts RMS.

• Over 10,000 watts peak for 40milliseconds and 6600 watts RMS continuous into a 1.5 ohm load.
• 40 mSec pulses of up to 210 amperes peak into a 0.5 ohm load.
• System output of 650 volts and 250 amperes maximum are possible with multiple, interconnected amplifiers.
• Frequency bandwidth of DC to 50kHz at rated power, DC to 100kHz at reduced power.
• Rugged chassis for stand-alone or rack mounted operation. No additional power supplies are required.
• Protection circuitry protects the AE Techron 7796 from input overloads, improper output connection (including shorted and improper loads), over-temperature, over-current, and supply voltages that are too high or low.
• Shipped ready to operate from 208 volt, three-phase AC mains. Operation from 380 or 415 volt AC mains are available on request

• Front panel LEDs indicate ready, standby and fault conditions in output stage.
• Front panel display lists type of fault condition and gives suggested corrective action.
• Front panel soft touch switch to place amplifier in run or standby mode.
• Front Panel is user configurable for up to four simultaneous displays reporting one, two or all four of the following: Voltage Peak, Voltage RMS, Current Peak, and Current RMS.
