MJ Series High Voltage AC/DC Power Supplies

Input Voltage 105-250 VAC; Max. Output Voltage 3-30 kVDC; Max. Power 15 W; Voltage Regulation <0.005%; Current Regulation <0.1%

XP Glassman’s MJ Series of 15 W high voltage AC/DC power supplies are air-insulated, fast-response, chassis-mount units with tight regulation and low arc discharge currents. A broad range of models is available with output voltage ranges from 0 to 3 kVDC through 0 to 30 kVDC.

The MJ Series’ current regulation is unequalled in a module of this price range. For example, the regulation from short circuit to rated voltage for the 15 kV, 1 mA model is ±500 nA. Overload, short circuit and arc protection is provided by automatic current regulation and by careful surge limiting design. XP Glassman’s “Air Insulated” designs are completely serviceable, these modules are not epoxy block “throw-away” power supplies.

The MJ Series’ standard operation mode is constant voltage/current with less than 200 mJ of stored energy for most models. A “multi-mode” operation mode permits maximum user flexibility. Local voltage or current control is user selectable, and the MJ Series power supplies feature remote voltage and/or current control via 0 to +10 V signal or potentiometers. External interlock terminals allow enable/disable of the power supply via TTL signal.

Standard accessories for the MJ Series include a detachable 2,4 m shielded output cable and mating control connector.

The MJ Series supplies with 230 VAC input option (198 to 253 VAC RMS, 48 to 63 Hz) are fully compliant with the following European directives:

• EN61000-3-2, Line Harmonics
