Wide bandwidth precision voltage and current amplifiers

High frequency, high current testing of very low impedance loads

LPA05A & LPA05B laboratory power amplifiers provide wide bandwidth signal amplification at up to 8A peak, extending the range of industrial and laboratory applications into which the LPA series can be used.

The LPA range of Laboratory Power Amplifiers from N4L provide AC and DC coupled wide band amplification for a wide variety of industrial and laboratory applications. All LPA amplifiers exhibit a 1MHz bandwidth and range from 400Vpk, 50mA models to 18Vpk, 5Arms models.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 at frequencies up to 1MHz.

They combine DC accuracy with wide bandwidth to faithfully reproduce complex wave forms, driving loads that may be resistive or reactive.Applications for which the LPA amplifiers can be used within are wide ranging, from Piezo transducer testing to materials analysis of dielectrics where high voltage DC offsets are required.

The LPA can be coupled with an N4L PSM Frequency Response Analyzer and external current shunt to provide a flexible impedance measurement system able to drive DUT’s at higher voltages and currents normally possible using traditional LCR measurement methods.
