Power Amplifier ±400Vpk 1MHz – Overview

The Power Amplifier LPA400 range of power amplifiers from N4L is robust and reliable for use in a variety of industrial and laboratory applications. Designed originally for use with Phase Sensitive Multimeters, they can also be used anywhere where there is a need to boost a signal either in voltage or current. They combine DC accuracy with wide bandwidth to faithfully reproduce complex waveforms, driving loads that may be capacitive, inductive, or resistive.  Optionally, the DC component can be eliminated with AC coupling or can be reduced with AC+(DC) coupling. To limit high-frequency noise, the input bandwidth can be reduced with a linear phase, 2nd order, low pass filter for low-frequency applications.
