Product Overview

RENT AE TECHRON 7548 (Call for Availability)

The AE Techron 7548 amplifier is a DC-enabled, high-powered unit designed to provide very low noise and fast slew rates. It can operate in either voltage or current mode and can safely drive a wide range of resistive, inductive loads. The AE Techron 7548 amplifier is typically used as a power source for EMC testing in applications that require both continuous AC or DC signals and significant short term signals.

Features and Specifications of the AE Techron 7548 Amplifier include:

• Features:
• Over 12,000 watts peak for 40 mSec and 5,500 watts peak continuous into a 1-ohm load
