Product catalog summary
Overview:
The document provides detailed specifications and features of the LPA01 and LPA400 laboratory power amplifiers developed by Newtons4th Ltd. These amplifiers are designed for high accuracy amplification in industrial and laboratory environments.

Features:
  • DC accurate with wide bandwidth.
  • Switch selectable coupling options: AC, AC+DC, or AC with reduced DC.
  • Precision gain settings and bandwidth selection.
  • High slew rate and robust metal enclosure.
  • Isolated from ground to prevent earth loops.
  • Unconditionally stable into any load.

Applications:
  • LPA01: High frequency, high current testing of wound components and excitation of servos and actuators up to 1A.
  • LPA400: High voltage, high frequency calibration and driving high voltage actuators up to ±400V.

Specifications:
  • Input connector: Isolated BNC with 10kΩ impedance.
  • Peak input voltage: LPA01 up to ±14V, LPA400 up to ±8V, LPA400B up to ±3.6V.
  • Full power bandwidth: LPA01 up to 1MHz, LPA400 up to 100kHz.
  • Gain options: LPA01 x1, x4, x10; LPA400 x50, x200, x500.
  • Operating temperature range: 0 - 40°C.
  • Power source: 90 – 265 Vrms @ 47 – 63 Hz.

Performance:
  • Total Harmonic Distortion is typically less than 0.6% for frequencies up to 1MHz.
  • Graphical data shows the effect of Total Harmonic Distortion on maximum output voltage at higher frequencies up to 5MHz.

Additional Information:
  • The LPA range is designed to work with the PSM range of Phase Sensitive Multimeters, which includes models like PSM1700, PSM1735, PSM2200, and PSM2201.
  • These amplifiers are manufactured in the UK by Newtons4th Ltd.

LPA400 Laboratory Power Amplifier-2

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, the...
