LPA01 Laboratory Power Amplifier is a wide bandwidth DC accurate amplifier developed to provide high accuracy amplification in an industrial or laboratory environment.
The LPA Laboratory Power Amplifier range of power amplifiers from Newtons4th Ltd are robust and reliable for use in a variety of industrial and laboratory applications. Designed originally for use with the PSM range frequency respsonse analyzers, 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 at the output of the laboratory power amplifier 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.
