7228 Datasheet
The AE Techron 7228 Linear Power Amplifier produces 1000W RMS model AC power up to 20kHz, and for high-power applications, up to 100kHz. This model operates at a small signal bandwith of 8Vp-p to 1MHz and outputs 16A of DC power at 13.5VDC. In continuous operation, a 7228 can provide up to four times the output power of the base model at frequencies above 100 kHz. If more current or power is needed, amplifiers can be combined in series or parallel and operate as a single system. Back-panel switches allow the AE Techron’s 7228 Linear Power Amplifier to be configured by the user for high-voltage/low-current, medium voltage and current, or low-voltage/high-current applications. Residual noise, slew rate, and gain linearity have all been improved over the base model. It can safely drive a wide range of resistive, inductive loads. The 7228 is typically used to create waveforms as required by a variety of EMC standards for DC powered electronics like DO-160, and MIL STD 461. It can also be used as a gradient amplifier for very small bore, high-gain MRI and NMR systems.

The AE Techron 7228 Linear Power Amplifier is the third model in the AE Techron 7220 DC-enabled Linear Power Amplifier Series.
AE Techron 7228 Features
  • Up to 4X the long-term power of the 7224 at frequencies above 100 kHz
  • Changes to protection, connection type and modes of operation are accomplished quickly by changing back-panel DIP switches or via remote contact closure
  • Provides user-selectable current limit, DC Blocking and DC Servo for transformer-based loads
  • Series or Parallel systems can be configured using back-panel DIP switches or remote contact closure
  • Ballast resistors are not required for connecting multiple amps in parallel
  • Monitors for excessive ground currents and moves to Standby when these conditions occur
  • Variable-speed, thermostatically controlled cooling fans minimize noise and reduce the fatigue of test personnel
  • Stable when driving highly capacitive loads
  • Four-quadrant operation
