Home » N4L LPA series broadband signal amplifiers
Newtons4th’s N4L LPA range of power amplifiers is a robust and reliable design for use in a variety of industrial and laboratory applications. Originally designed for use with the PSM range (Phase Sensitive Multimeters) and Frequency Response Analyzers (FRA). But also widely used in applications where it is necessary to amplify a voltage or current signal. The LPA amplifiers combine DC accuracy with a relatively high bandwidth to faithfully reproduce complex waveforms, suitable for loads that can be capacitive, inductive or ohmic. If desired, the DC component can be eliminated with AC coupling, and AC + DC coupling is also possible. Any unwanted high frequency noise can be reduced with a linear phase, 2nd order, low pass filter for low frequency applications. The gain of the amplifier is selectable from three Gain settings.
The amplifiers of the N4L LPA series can be used in a wide range of applications including: High frequency currents up to 5A for testing inductances and wound components. High frequency excitation of servos and actuators, and for driving high voltage actuators (e.g. piezo). Depending on the model, voltages up to +/- 400 and 8A are feasible with these LPA amplifiers.

"The ABB Power Grids Jumet organisation is an innovative development and production facility of ABB that manufactures active filters and battery energy storage systems to support a stable grid. To test these systems we have acquired two Cinergia GE/EL +120kVA eplus units capable of doing grid emulation (AC + DC), operating as an electronic load (AC +DC) and being a battery emulator. We have experienced very good support from TTMS in obtaining these two Cinergia units. This included organising an on-site demonstration and supplying loan systems prior to the delivery of our final systems. This way we could start testing as early as possible. TTMS also organised training for the operators from the original manufacturer. This support allowed us to introduce the first battery energy storage systems even prior to the full delivery of the Cinergia systems."

“At the Energy and Environment department of the Faculty of Science, Technology and Medicine (FSTM) of the University of Luxembourg we do have different research projects related to green energy contributing to the development of eco-cities. As a long-standing partner of our research unit, TT&MS has proven that they are able to answer even the most complex questions in a professional manner. They have shown that they are always up to date with the latest technology and do not spare any effort to look at the application and even the situation on site. The exchange of ideas was always very pleasant and took place quickly. We look forward to further years of fruitful cooperation.”
