our web site for typical applications.
The MK Series with 220 option, are fully compliant with the Following European Directives:
EN61000-3-2, Line Harmonics.
EN61010/ IEC61010, Safety
EN61000-6-4, Conducted and Radiated Emissions
EN61000-6-2:2005, Conducted and RadiatedImmunity
2011/65/EU, Restriction of the use of hazardous
substances (RoHS)

Models from 0-1kVDC through 0-60kVDC; weight <11 lbs.

Features:
Current Regulation Unequalled
in a Module of This Price Range.
For example, the regulation from shortcircuit to rated voltage for the 15kV,
5mA model is +2.5 microamperes.
Glassman’s “Air Insulated” designs arecompletely serviceable; this module
is not an epoxy block “throw-away.”
