Current DC Sources

The current source modules have been designed to drive the corrector magnets required for steering a particle beam, but, they are also useful for any other applications when fast settling or high stability is required:

  • The fast settling models perform settling time shorter than 70µs compliant with a data rate up to 10KHz
  • The low drift and low ripple models perform stability and resolution within the 5ppm range, while the current settles to the noise free maximum resolution of 19 bit within 20ms.
In addition, low drift models can drive any inductive load as well as non inductive loads.
Laser diodes test and superconducting coils biasing are some examples of numerous applications.
When testing laser diodes, optional AC modulation input is available for BE2811 & BE2812, in the 1KHz to 100KHz range.
