Precision High Voltage Amplifiers

UltraVolt, Inc., announced expansion of its popular line of precision high-voltage amplifiers - the HVA Series - capable of operating in DC, reversible, and amplifier modes. The new line of precision high-voltage amplifiers, the 10HVA-20HVA Series, is available with unipolar or bipolar output at 0 to 10kV, 15kV and 20kV. Together with UltraVolt's original line of high-voltage amplifiers, the HVA Series, designers have (8) voltage ranges choices from 0 to 1kV through 20kV. 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.
