AE Techron 7224 Audio Bandwidth Power Amplifier DC 300 kHz 1100W

Description

The AE Techron 7224 is a 4-quadrant power amplifier that offers the features of larger industrial amplifiers in a smaller 2U size that runs from single phase 120/230VAC. It features DC - 300 kHz bandwidth, controlled-current or controlled-voltage modes of operation and has a wide range of field-configurable options. 7224 with "P" option offers precision control of output offset, DC drift and gain linearity.

EMC
The 7224 is recognized by Ford Motor Company for use in CS2009 EMC testing; specifically for doing Radiated Immunity measurements in sections RI 140 RI 150 and doing conducted immunity sections CI 210, CI 230, CI 250, and CI 260. It is also recognized as valid for use in similar conducted and radiated immunity tests found in MIL STD 1275D, MIL STD 461, DO 160, SAE J1113-2, ISO 16750, General Motors GMW3172 and Chrysler CS-11809.

Research
In only two years, the 7224s configurability and flexibility have made it the choice of many research and university labs. It can be field-configured to run well into loads from 100 ohms to as low as 0.5 ohms. Even with its small bench top size, the 7224 is able to produce as much as 50 amps of current and as much as 158 volts, providing serious power for a wide range of applications and experiments. With its 70 volt per micro second slew rate, it is able to accurately reproduce wave forms from DC to above 300 kHz, making it a great choice for high-speed control applications. With its ability to operate in either Controlled Voltage or Controlled Current modes, it has been used in Small Bore MRI and NMR systems, testing of switch-mode power supply components, and driving Helmholtz coils.

Features

  • Frequency bandwidth of DC to 300 kHz at rated power
  • Continuous output of over 1,100 watts RMS at 4 ohms
  • 40 mSec pulses of up to 52 amperes peak into a 0.5 ohm load
  • System output of over 4,000 watts or over 200 amperes maximum is possible with multiple, interconnected amplifiers
  • Efficient design and light weight chassis materials allow amplifier to occupy only 2U height and weight only 41 lbs
  • Protection circuitry protects the AE Techron 7224 from input overloads, improper output connection (including shorted and improper loads), over-temperature, over-current, and supply voltages that are too high or low
  • 7224 with “P” option offers precision control of output offset, DC drift and gain linearity.
  • Shipped ready to operate from 120-volt (±10%) single-phase AC mains; 220/240-volt model available on request
