A1520#

The A1520 from HUBERT is a powerful 4-quadrant voltage and current amplifier that offers exceptional flexibility and precision.

The A1520 is a linear, extremely broadband precision power amplifier for all applications that require rapidly changing signals with high power. It can be operated as a voltage or current amplifier and offers a constant, frequency-invariant output current for inductive loads. When operated as a current amplifier, it can adapt to almost any application “on the fly” thanks to fully automatic load detection.
