Data Sheet

Precision hot-switchable polarity reversing modules

Spellman’s MXE series is a family of high voltage, high performance, ultra-compact, hot-switchable polarity reversing modules with output voltages rang ing from 2.5kV to 10kV.

The MXE series is controlled via analog interface, provided via a standard 15-pin D-type connector. The units feature a differential voltage program input for low noise control and TTL compatible Enable and Polarity control signal inputs.

Spellman’s advanced low noise, high stability technology provides the high quality and performance needed for precision applications.

Typical Applications：

Mass Spectrometry
Automatic Test Equipment
Capillary Electrophoresis
