LTR Series

Precision High Voltage Modules

LT001, LT2.5, LT005, LT010, LT015, LT020, LT030

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

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

The LT Series builds on the new standard for high voltage precision and stability set by the LS 1W family. By optimising the Low Stress™ technologies pioneered in the LS family, the LT Series provides 3W o/p capability, but still has less than 2ppm ripple, 10ppm/°C temperature coefficient, and 75ppm drift/hr throughout the range, while retaining the same LS case dimensions.

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 +ve or -ve 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.
