GA-150 Amplifier

Specifications: 150 Volt / 150 Amp

The GA-150 is a 150 VDC, 75 Arms, 150 Apk pulse width modulated power amplifier, intended for use in precision control systems. 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.
