LS Series

Precision High Voltage Modules

LS001, LS2.5, LS005, LS010, LS015, LS020, LS030, LS050

Applications: Mass spectrometers, Electron microscopes, Nuclear instruments, Photomultiplier tubes, Microchannel plates

  • 1kV, 2.5kV, 5kV, 10kV, 15kV, 20kV, 30kV, 50kV
  • Highest Stability, Lowest Ripple, Lowest Drift
  • Externally programmable or Internal control (opt)
  • Short circuit and flashover proof
  • 24 hour burn in
  • Low radiated magnetic field
  • Positive, negative & remote reversible versions

The LS Series sets a new standard for high voltage precision and stability. By optimizing the Low Stress™ technologies used in our leading 10 Watt HP Series for 1 Watt applications, the new LS Series has less than 1ppm ripple, 10ppm/°C temperature coefficient, and 50ppm drift/hr throughout the range. Each of the units includes a differential control input.

All units are short circuit proof and use proven techniques to drive a high frequency oscillator and ferrite high voltage step-up transformer. These advanced power supplies build on Applied Kilovolts' legendary reputation for reliability, being constructed from conservatively rated components with their reliability further enhanced by information gained over many years of field operation.

Available as positive and negative units up to 50kV, and electrically reversible at voltages up to 30kV. Please see the HPZ range for zero crossing reversible (bi-polar) units.

We manufacture a large number of customized OEM versions and would be pleased to discuss your application with you.
