High Performance High Voltage Power Supply
Spellman’s MX20 is a well-regulated high performance DC-DC converter featuring a “hot switchable” polarity reversal capability. The MX20’s low ripple specification makes it ideal for Mass Spectrometry applications; especially security detection systems, Dynodes, sample ionization as well as capillary electrophoresis and electrostatic printing applications.
The MX20 is rated at 20kV @ 100uA and is packaged in a shielded metal enclosure. This unit features a logic signal input to control output polarity reversal. A HV inhibit feature, along with voltage and current monitors are provided. Easily customized to meet OEM requirements, the MX20 can be provided with current control, improved ripple performance and higher voltage and current capabilities.
Typical applications:
- Mass Spectrometry
- Capillary Electrophoresis
- Electrostatic Printing
