MASS SPECTROMETRY
HIGH VOLTAGE POWER SUPPLY
- Voltage range: ±3kV to ±30kV
- Current: 0.25mA to 10mA
- Power: 7.5W to 10W
- Reversible Polarity
Exceptionally low ripple and high stability designed for high-resolution Mass Spectrometry applications
KAS-R series is an ultra-low-ripple and highly stable high-voltage power supply. It is the perfect choice for Mass Spectrometry (MS) applications. You can control the output polarity with an external signal.
FEATURES AND BENEFITS
- Designed for Time of Flight Mass Spectrometry (TOF-MS) applications
- High Stability 10 ppm/hr.
- Ultra low ripple and High stability
- Reversible polarity by external signal
- Output voltage and current monitor
- Digital control (Option)
