GA151, 1-Axis Gradient Amplifier
The GA151 Gradient Amplifier from Performance Controls, Inc. (PCI) is a single axis pulse width modulated amplifier. It is rated at 150 VDC, 75 Arms, 150 Apk and operates from a DC power source. The GA151’s exceptionally low output noise, extremely high bandwidth and excellent stability make it ideally suited for demanding power amplifier tasks found in laboratory and medical applications.
The GA151 is backward compatible with the GA-150 gradient amplifier it replaces. Utilizing advanced hybrid digital and analog control architecture, the GA151 provides a host of powerful features. These include digital tuning, digital set-up, diagnostic tools, programmable protection for loads, and more. One such feature is the Integrated Digital Storage Oscilloscope (iDSO™). These features are easily accessible with the companion InSight™ software toolkit.
