GA-150, 1-Axis Gradient Amplifier (Legacy)
The GA150 is a 150 VDC, 75 Arms, 150 Apk pulse width modulated power amplifier, intended for use in precision applications such as MRI scanning and others. The amplifier operates from a single source of power and provides a precisely controlled, high fidelity output current. The amplifier is packaged to fit in a standard 19” rack width with a 5.25” height (3U) and 25.75” depth penetration into the rack. This power amplifier has been designed to operate in a controlled environment and to be enclosed within the overall system enclosure.
