NF corporation expands the HSA series bipolar amplifiers out with the new model HSA42052.
The HSA series already consisted of three precision amplifiers for reproducing the most complex waveforms. With an external signal generator, the waveforms can be amplified up to 150Vp-p with fixed values of 1x, 10x, 20x and 50x. Variable amplification is also possible between 1 to 3x the input voltage. These amplifiers have a bandwidth from DC to 1MHz and are therefore unique in the high frequency market with these high voltages and currents. They have a rise time of 475V per microsecond and a very low output impedance that is adjustable. There are three models in this series with a maximum of 3Ap-p, 6Ap-p and 12Ap-p.
The expansion with the HSA42052 ensures a voltage range of up to 300Vp-p. The frequency range of this unit is limited to 500kHz and the maximum current is 5.66Ap-p. Need a higher voltage or power? With all HSA models we can double the voltage and power using a second unit and an inverse input.
FUNCTIONALITY
The amplification factor of the HSA can be adjusted continuously and accurately using a precision potentiometer. If higher voltages are required, 2 amplifiers can be connected using a balanced arrangement. With the DC bias output you can easily add an offset to the amplified waveform. To ensure safe use and prevent damage to the amplifier, the NF HSA series is equipped with overvoltage and overload protection.
APPLICATIONS
Due to the bipolar design of the 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. The HSA is therefore extremely suitable for controlling inductive and capacitive loads.
This makes the unit also suitable for applications such as impedance measurements on capacitances, coils, transformers and batteries. The demand for new developments in the field of multi-layer ceramic capacitors for automotive applications is increasing rapidly. The intended capacity is increased with the smallest possible housing. In combination with a frequency analyzer the HSA amplifier is ideal for developing, testing and characterizing these capacitors.
This amplifier can also be used perfectly for measuring resonance characteristics of piezoelectric elements or evaluating the hysteresis curve of magnetic materials.
In summary, the HSA from NF Corporation is a very complete amplifier that can be used under the most demanding conditions.
