The DA2200-2 Gradient Amplifier from Performance Controls, Inc. (PCI) is a three-axis pulse width modulated amplifier system. The internal DC power supply output voltage can be configured by the MRI OEM and is protected by a redundant hardware/software interlock. The DA2200-2’s exceptionally low output noise, high bandwidth and rock-solid stability make it ideally suited for demanding power amplifier tasks found in laboratory and medical applications.

PCI’s new D-SERIES™ technology is the foundation for the DA2200-2’s many powerful features. Coupled with PCI’s new InSight™ software toolkit, D-SERIES™ technology gives systems engineers, sequence developers, and field service technicians unprecedented insight and capability for maximizing system performance, lowering overall system costs, and ensuring maximum system uptime.


The DA2200-2 Gradient Amplifier can be used in these and other applications:

  • MRI magnetic field gradient control
  • Particle beam magnetic steering control
  • Any inductive load requiring precise control of large currents across a wide frequency range
