  • Service & Support


Advanced Energy’s MSRL series features ultra-low ripple, precision mass spectrometry power supply modules. They are ideal for high resolution, slow switching applications in sample ionization and time-of-flight (ToF) mass filters. The series combines a reversible output voltage with high stability, excellent repeatability, and reliable performance. The MSRL's modular design provides performance features that include customizable cable length and connector types.


  • Ensure consistent performance over extended operation periods via high stability and low drift
  • Reduce system integration costs due to rebus design and input signal noise tolerance
  • Utilize MSRL modules' small footprint for mass spectrometer sample ionization or ToF mass filter applications
  • Decrease costs by selecting only needed high voltage capabilities


  • Ultra-low ripple (as low as 10 mV) and high stability with low drift
  • Robust design, tolerant of input signal noise
  • Compact modular design, with reversible output polarity
  • Choice of five different models; customer-defined derivatives upon request
