- Reversible Polarity
Ultra low noise and high stability high voltage power supply
The K12-R series is a high-voltage power supply module with reversible output polarity. This high-performance module is engineered for applications demanding exceptional voltage stability, such as mass spectrometry (MS) and ion beam systems, where seamless switching between positive and negative polarity is essential.
This series strikes a high-level balance between the often-conflicting requirements of ultra-low ripple and high stability. Its output polarity can be switched rapidly via an external signal, allowing a single unit to handle the anion and cation switching required in MS and ion beam applications. This flexibility also makes it adaptable to various polarity switching sequences in diverse experiments and equipment, including materials testing.
The K12-R series is the ideal choice for high-voltage power supplies for the acceleration, focusing, and reflector electrodes in the mass analyzer section of Time-of-Flight Mass Spectrometry (TOF-MS).

LAN/USB/RS-232C/RS-485/GPIB Control
To remotely control this high-voltage power supply via LAN or USB, purchase both a digital converter (CO-HV) and an optical isolation adapter. The digital converter (CO-HV) converts the analog control signal of the high-voltage power supply into a digital optical signal. The optical isolation adapter converts interface signals such as LAN and USB to optical signals.For details, check the CO/USB series for a digital converter (CO-HV) and optical isolation adapter.
Refer to CO/USB series- Optical isolation
