LPA Series: Wide bandwidth precision voltage and current amplifiers
The LPA range of Power Amplifiers from N4L provide AC and DC coupled wideband amplfication for a wide variety of industrial and laboratory applications. Designed originally for use with N4L Phase Sensitive Multimeters, they can also be used anywhere where there is a need to boost a signal in either voltage or current.
They combine DC accuracy with wide bandwidth to faithfully reproduce complex waveforms, driving loads that may be resistive or reactive.
