Hot-Switchable Polarity Reversing Power Supply
Spellman’s MXR Series are well-regulated high performance DC-DC converters. The MXR’s low ripple specification makes it ideal for Mass Spectrometry and electron microscopes. The MXR20 is rated at 20kV @ 300uA and MXR30 is rated at 30kV @ 300uA. Both are packaged in a shielded metal enclosure. These units feature 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 MXR Series can be provided with current control, improved ripple performance and higher voltage and current capabilities.
Typical applications:
- Mass Spectrometry
- Electron Microscopes
- Capillary Electrophoresis
- Electrostatic Printing
