High Performance High Voltage Power Supply

Spellman’s RoHS compliant MX10 Plus is a well-regulated high performance fast reversible dynode supply featuring a 25ms “hot switchable” polarity reversing capability with an integrated -2.3kV electron multiplier supply.

The MX10 Plus’s low ripple specification is typical of the topologies that make Spellman High Voltage your ideal choice for mass spectrometry applications; especially security detection systems, dynodes, sample ionisation as well as capillary electrophoresis and electrostatic printing applications. The MX10 Plus has been designed espe­cially for dynode detector applications.

The MX10 Plus can be easily tailored to an OEM’s requirement, such as improved ripple performance, or different voltage and/or current capabilities.

Typical applications:

• Dynode Supply
• Electron Multiplier Supply
