AE Techron 7114 High-speed AC/DC Amplifier
Description
AE Techron 7114 High-speed AC/DC Amplifier is a 400-VA, four-quadrant, AC and DC amplifier that provides exceptional versatility and value. Compact size, user configurability, DC-Max™ topology, and AE Techron toughness makes the 7114 the ideal lab partner for automotive conducted immunity testing, PSRR testing, or any application where more voltage or current is needed than is available from the signal source.
Front panel user controls give the 7114 a wide range of possible uses; gain, maximum current, and DC offset can be fixed or infinitely varied. The choice of AC or DC coupling makes it suitable both for DC applications and for driving objects like coupling transformers or piezo elements that shouldn’t see DC.
