Product Overview

RENT AE TECHRON 7796 (Call for Availability)

The AE Techron 7796 amplifier is a DC-enabled, high-powered unit designed to provide clean, reliable, power for gradient coils in magnetic resonance imaging systems or in applications that require both significant burst and continuous power. A single AE Techron 7796 Amplifier has an output capability of over 210 amperes peak at its rated voltage. If more current is needed, up to four amplifiers can be combined in parallel and operate as a single system.

Features and Specifications of the AE Techron 7796 Amplifier include:
