N4L LPA01/400A/400B/05A/05B Newton power amplifier

N4L LPA01/400A/400B/05A/05B Newton power amplifier

Model:LPA01/400A/400B/05A/05B      Country of Origin:UK

Category:Precision Bipolar Power Amplifier

Overview:

The LPA01 is a wide bandwidth DC precision amplifier developed to provide high accuracy amplification in industrial or laboratory environments. The LPA range of power amplifiers from Newtons4th Ltd are powerful and reliable for use in a variety of industrial and laboratory applications. Originally designed for use with the PSM range of frequency response analyzers, they can also be used anywhere there is a need to boost a signal, whether in voltage or current. They combine DC accuracy with wide bandwidth to faithfully reproduce complex waveforms and drive 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, second order low pass filter for low frequency applications.
