XP Glassman’s OQ Series of high voltage AC/DC power supplies are sophisticated 8 or 16 kW open stack power supplies with extremely low ripple and noise. They are air insulated fast response units with tight regulation. A range of models is available with output voltage ranges from 0 to 200 kVDC through 0 to 500 kVDC. One master supply and up to 4 slave supplies can be run in parallel, providing a maximum of 25 to 40 kW depending on the maximum DC voltage.

OQ Series power supplies consist of a rack-style driver chassis, a high voltage stack assembly and a remote-control unit. The dimensions of the stack vary with the output voltage rating and are given in the specifications in the downloadable datasheet. The driver chassis is provided in a cabinet with 275.8 mm height x 501.7 mm width x 636.5 mm depth. The remote-control unit size is 132.5 mm height x 482.6 mm width x 186,3 mm depth.

The OQ 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 OQ Series’ high voltage output is inhibited for a short period after each load arc to help extinguish the arc.

Typically, ripple is less than 0.1% peak-to-peak of rated voltage at full load. Off-the-line pulse-width modulation (PWM) provides high efficiency and a reduced parts count for improved reliability. The OQ Series’ standard operation mode is constant voltage/current. Automatic crossover from constant-voltage to constant-current regulation provides protection against overloads, arcs and short circuits. A current-trip feature may be substituted for constant-current operation by a remote-control chassis rear panel selector switch.

Standard accessories for the OQ Series include 7.6 m of detachable interconnect cables, null modem cable and USB cable.

The OQ Series supplies are fully compliant with the following European directives:

EN61010/ IEC61010, Safety
EN61000-6-4, Conducted and Radiated Emissions
EN61000-6-2:2005, Conducted and Radiated Immunity
