Applied Kilovolts - Model HPR Series - HPR Series Precision High Voltage Modules
The HPR Series from Applied Kilovolts offers precision high voltage modules engineered to provide a stable and low ripple high voltage supply for applications demanding stringent specifications like photomultiplier tubes, mass spectrometers, electron microscopes, and various nuclear instruments. Featuring output voltages ranging from 0.5kV to 30kV, these units are known for their high stability and low radiated magnetic field. Each module can be configured using an internal potentiometer or an external 10-volt analogue control voltage, allowing flexible voltage control. Built with a high frequency FET oscillator and a ferrite step-up transformer, these modules utilize established linear regulator techniques to ensure performance reliability. The series includes positive, negative, and remote reversible versions, with short circuit protection as standard. Additionally, a unique reversible design is implemented for safety, ensuring changes in output polarity only occur when the output is zero. The series is UL recognized, enhancing the trust in its application across various demanding environments.Applications: Photomultiplier tubes, Mass spectrometers, Electron microscopes, Nuclear instruments, Microchannel plates

This range of precision high voltage modules has outputs that provide a low ripple, high stability source of high voltage for photomultiplier tubes, electron gun, nuclear and other applications. Control of the output voltage is by internal potentiometer or by an external 10 volt analogue control voltage. The units are pin compatible with the medium stability KS and 100 watt HW ranges.
All units are short circuit proof and use proven linear regulator techniques to drive a high frequency FET oscillator and ferrite high voltage step-up transformer. The power supplies are constructed from conservatively rated components with the reliability further enhanced by information gained over many years of field operation.
Positive, negative, and electrically reversible outputs are available at voltages from 1kV to 30kV. This reversible HPR version has a latched output and can only be changed when the output is set to zero. Please see the HPZ range for zero crossing reversible (bi-polar) units.
We manufacture a large number of special versions of these units and would be pleased to discuss your application with you.
