The 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 - 400 kHz bandwidth, controlled-current or controlled-voltage modes of operation and has a wide range of field-configurable options.

The 7224’s 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 75V/µS slew rate, it is able to accurately reproduce wave forms from DC to above 400 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

  • Stable when driving highly capacitive loads.
  • Four-quadrant operation.
  • User-selectable controlled-voltage or controlled-current modes of operation.
  • System output of over 3,600 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 weighs only 41 lbs.
  • Protection circuitry protects the amplifier from input overloads, improper output connection (including shorted and improper loads), overtemperature, over-current, and supply voltages that are too high or low.
  • Shipped ready to operate from 120-volt (±10%) single-phase AC mains; 220/240-volt model available on request.
