Home » Products » The HSA series of bipolar amplifiers from NF corporation
NF corporation has expanded its HSA series of bipolar amplifiers with three new models. The amplifiers have a bandwidth of DC to 1MHz and have a high switching speed of 475V per microsecond. With an external signal generator (max 10V input), the waveforms can be amplified up to 150Vp-p at a maximum current of 3Ap-p, 6Ap-p and 12Ap-p. All this at a very low output impedance that is also adjustable.
Due to the bipolar design of the NF HSA series, the amplifier is operational in all 4 quadrants. This makes it possible to supply and absorb current at both positive and negative voltages. This makes the HSA extremely suitable for driving inductive and capacitive loads.
HSA42011 DC-1MHz, 0-150Vp-p, 0-3Ap-p, DC offset,
HSA42012 DC-1MHz, 0-150Vp-p, 0-6Ap-p, DC offset,
HSA42014 DC-1MHz, 0-150Vp-p, 0-12Ap-p, DC offset,
The gain of the HSA bipolar amplifiers can be infinitely and precisely adjusted with a precision potentiometer. Fixed gain factors are also available: 1x, 10x, 20x and 50x. If higher voltages are required, 2 amplifiers can be coupled in a balanced arrangement. With the DC bias output, an offset can easily be added to the amplified waveform.
The four quadrant design of the HSA bipolar amplifier makes the unit suitable for applications involving the control of capacitors, coils, transformers and, for example, batteries. Think for example of multilayer ceramic capacitors for applications in the automotive industry. The capacity becomes higher and the housing smaller. In combination with a frequency analyzer, the HSA amplifier lends itself extremely well to the characterisation of these capacitors.
It can also be used to measure the resonance characteristics of piezoelectric elements or to evaluate the hysteresis curve of magnetic materials.
The NF corporation HSA series is widely used for driving the most challenging applications.

"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.”
