MX20

  • 20kV Hot Switchable Polarity Reversible Via a Logic Signal
  • Well-Regulated, Low Ripple
  • Polarity Reversal Within 500mS
  • Flying High Voltage Output Cable

고성능 고전압 전원 공급 장치

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
