Catalog excerpts

Laboratory power amplifiers DC accurate and wide bandwidth Switch selectable coupling options: AC, AC+DC or AC with reduced DC. Switch selectable precision gain settings. Switch selectable bandwidth. High slew rate. 1A Peak output current @ up to 14V peak (LPA01). Unconditionally stable into any load. Isolated from ground to prevent earth loops. Robust metal enclosure Will fit underneath QuanteQ or Veqtor to boost output capability. LPA01 & LPA400 are the first in a range of amplifiers developed to provide high accuracy amplification in an industrial or laboratory environment. LPA01: High frequency, high current testing of wound components. High frequency excitation of servos and actuators up to 1A. LPA400: High voltage, high frequency calibration. Driving high voltage actuators (e.g. piezo) up to 400V.

The LPA range of power amplifiers from N4L are robust and reliable for use in a variety of industrial and laboratory applications. Designed originally for use with the PSM* range Phase Sensitive Multimeters, 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,...

Total Harmonic Distortion: For frequencies up to 1MHz, Total Harmonic Distortion is typically less than 0.6%. This graph demonstrates the effect of Total Harmonic Distortion on the Maximum Output Voltage of the LPA01 amplifier at higher frequency levels up to 5MHz. LPA01 Maximum Output (Vrms) with <10% THD. The PSM range includes the PSM1700, PSM1735, PSM2200 and PSM2201 that incorporate gain/phase analysis, LCR meter, phase angle voltmeter, wideband true rms meter, Power analyser, harmonic analyser and more. The LPA range is designed & manufactured in the UK by Newtons4th Ltd
