XP Glassman’s OS Series of high voltage AC/DC power supplies are sophisticated 2 kW open stack, power supplies with extremely low ripple and noise. They are air insulated fast response units with tight regulation.

OS Series power supplies are designed to meet the growing demands from both users and electric utilities for switching supplies with excellent input power factors that draw harmonic currents below those specified in EN61000-3-2. A range of models is available with output voltage ranges from 0 to 200 kVDC through 0 to 450 kVDC.

OS Series models consist of a rack-style driver chassis, a high voltage stack assembly and a remote-control unit. The driver chassis is provided in a cabinet with 214.1 mm height x 573 mm depth, onto which the high voltage stack is mounted. The dimensions of the stack vary with the output voltage rating and are given in the specifications in the downloadable datasheet. The rack-mountable remote control provides all interface functions and is connected to the driver chassis with the 7.6 m long cables provided. The remote-control unit size is 132.5 mm height x 127 mm depth.

Active correction circuitry (power factor correction, PFC) achieves an input line current harmonic content well below the maximum specified in EN61000-3-2. The OS 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 OS Series’ high voltage output is inhibited for a short period after each load arc to help extinguish the arc.

Typically, ripple is less than 0.05% 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 OS 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 KT Series include a detachable 2,4 m shielded high voltage coaxial output cable, line cord, null modem cable and USB cable.

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