UltraVolt Launches Expansion of Precision High Voltage Amplifiers

The new HVA modules provide a high-resolution, high-voltage DC to full scale waveform capability greater than 500 Hz+ output depending on loading. HVA units operate a precision filter/divider and linear HV switch to produce the high-voltage amplifier. The HVA Series can both source and sink current linearly through 0V with low ripple and low noise over the entire output range.



UltraVolt’s high-voltage amplifiers provide excellent line and load regulation and offer a fast slew rate (40V/µs) and high bandwidth at an excellent value compared to other technologies. The product line performs with a 25ppm temperature coefficient standard, 15ppm optional. The “-F” Ripple Stripper output filter option further reduces output ripple and noise. A differential precision, 0 to 10VDC control input as well as precision voltage and current monitors are standard.



The new 10kV, 15kV, and 20kV HVA modules are optimized for DC, reversible, and amplifier bias applications while providing excellent line regulation, load regulation, dynamic response, and stability. These modules also feature constant voltage / constant current auto crossover (CV/CC).



Typical HVA series applications include drivers for Pockel’s cell & electro-optic modulation and electrophoresis. This series is also optimized as an amplifier for ion beam and electron beam devices such as mass spectrometry and electron microscopes as well as beam electrostatic deflection/focusing, electrospinning, corona charging / discharging.



UltraVolt is excited to expand our HVA Series High Voltage Amplifier product line with 2x the unipolar output voltage and 4x the bipolar output voltage, said James Morrison, CEO and Co-Founder. The HVA Series offers a significant capability for a relatively low cost compared to other solutions, giving designers a new device to use in more exciting ways than ever before! HVA devices work well in Ion beam, Electron beam, Laser beam, and Electrophoresis applications. With the HVA’s fully featured digital-ready analog interface, getting experiments and proof-of-concept systems up and running quickly accelerates time-to-market efforts.
