Reversible Polarity, High-Stability High-Voltage Power Supply
- Voltage range: +1 kV/-1 kV to +10 kV/-10 kV
- Current: 0.3 mA to 3 mA
- Power: 3 W
- Reversible Polarity
Ultra-low noise and high-stability high-voltage power supply
The K3-R series is a high-voltage power supply module featuring reversible output polarity. Engineered for applications demanding exceptional stability—such as mass spectrometry (MS) and ion beam systems—this series allows for seamless switching between positive and negative polarity.
The K3-R series successfully balances ultra-low ripple with high stability, meeting the rigorous requirements of precision measurement. Its output polarity can be rapidly switched via an external control signal, enabling a single unit to handle both anion and cation detection. This flexibility makes it ideal for diverse experiments and equipment integration, including materials testing. The K3-R series is an excellent choice for biasing lenses and detectors in mass spectrometers.
