Laboratory Power Amplifier

 

 

Newtons4th Ltd-LPA400

Newtons4th Ltd-LPA400 is a wideband high volatge amplifier for an industrial or laboratory environment.

  • The LPA 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 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.
