Mass Spectrometry Power Supplies

The MSRL series has a latched output voltage polarity that can only be changed when the output voltage has been set to zero. These modules provide reliable operation even in short circuit or arc conditions. They can be set by internal potentiometer, external voltage, or external potentiometer.

The modular design of AE high voltage products for mass spectrometry enables an array of performance features and combinations. From simple options, such as cable length and connector type, to complete custom designs, we deliver solutions that precisely fulfill your specific requirements.
