XP Glassman’s MQ Series of 300 W high voltage AC/DC power supplies feature flexible embedded controls with low ripple and noise. They are air insulated, fast response, chassis-mount units with tight regulation and extremely low arc discharge currents. A broad range of models is available with output voltage ranges from 0 to 1 kVDC through 0 to 60 kVDC.
The MQ Series is a family of sophisticated, medium-power, high voltage AC/DC power supplies that complies with current international safety and EMI directives. XP Glassman has packaged this series as a space-saving module to avoid the expense of front panels and displays. However, no compromises in performance and/or operating features have been made. The result is a power supply series that offers outstanding value for a wide range of demanding applications.
The MQ series features “air” as the primary dielectric medium. No oil or encapsulation is used which would impede serviceability or increase weight. Internal circuitry constantly senses and integrates arcs that occur over a given time. In the event a system or load arcing problem develops and exceeds factory-set parameters, the power supply will cycle off in an attempt to clear the fault and then automatically restart after a preset “off dwell time”. The MQ Series’ high voltage output is inhibited for a short period after each load arc to help extinguish the arc.
Ripple is less than 0.025% of rated voltage at full load. Continuous, stable adjustment from 0 to rated voltage or current by panel-mounted 10-turn potentiometer with 0.05% resolution or by external 0 to 10 V signals is provided. Integral RS-232, USB and optional Ethernet communications provide remote control program and monitor. Automatic current regulation provides protection against all overloads, including arcs and short circuits. A connection made on the interface connector allows selection of either constant-current or current-trip operation.
Standard accessories for the MQ Series include a detachable 2,4 m shielded high voltage coaxial output cable, line cord, null modem cable and USB cable.
