Four-quadrant amplifiers
Four-quadrant amplifiers, like four-quadrant power supplies, are capable of both delivering current and absorbing current. And that at both positive and negative voltage. Four-quadrant amplifiers are used to increase amplitude or power.


These amplifiers are used in many applications. Most immediately think of audio amplifiers but there are also applications in the medical sphere, amplifying high-frequency signals, but also just simulation with harmonics and amplifying sensor signals. Nowadays, we also see many Power Hardware In the Loop applications.

TTMS a wide choice of models from multiple manufacturers.
Small units from 100W to high power units up to the MegaW. Voltages from ±10V to ± 880V. Currents from mA to in the kilo amps and frequencies up to 1MHz.

Get advice from one of the TTMS consultants when selecting the right amplifier for your application.

Besides power amplifiers, TTMS also has current and voltage amplifiers in its range. For amplifiers from pV and also current amplifiers from nA.
