The N4L LPA05 Series Laboratory Power Amplifiers provide wide bandwidth signal amplification at up to 8A peak, extending the range of industrial and laboratory applications. Designed originally for use with the PSM range Phase Sensitive Multimeters/Frequency Response Analyzers, the LPA05 Series can be used anywhere where there is a need to boost a signal either in voltage or current up to 1MHz. 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, lowpass filter for low frequency applications. A common application for the laboratory power amplifiers is in situations where is a requirement for impedance measurement of a device under high voltage bias or high current bias conditions. In these applications the combination of N4L PSM1700, PSM1735 or PSM3750 Phase Sensitive Multimeter (Frequency Response Analyzer) + LPA05 Series Laboratory Power Amplifier + HF Current Shunt form a high power impedance measurement system.
