The Model 7548 is a part of expanding line of new precision linear amplifiers; it combines everything we have learned in over 40 years of building high power linear amplifiers.

The AE Techron 7548 Amplifier is a high powered unit designed to provide very low noise and fast slew rates.  The 7548 can safely drive a wide range of resistive, inductive loads. Typical uses include signal amplifier for high gain gradient coils in magnetic resonance imaging systems or a power source EMC testing in applications that require both continuous AC or DC signals and significant short term (burst) signals (DO160, MIL 461, and MIL 704).

A single 7548 has an output capability of 100 amperes peak and 200 volts peak when driving typical MRI gradient coil loads*. If more power is needed, up to four amplifiers can be combined in series or parallel and operate as a single system. The 7548 operates in either voltage or current mode and features DC-coupling, robust output devices and a power range of over 3300 watts RMS.

• Over 12,000 watts peak for 40 milliseconds into a 1.5 ohm load.
• 40 mSec pulses of up to 72 amperes peak into a 1 ohm load.
• System output of 800 volts and 70 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 7548 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.
