Product information "LH Open Stack Series High Voltage AC/DC Power Supplies"

Input Voltage 187-460 VAC 3-Phase; Max. Output Voltage 200-500 kVDC; Max. Power 4,000, 8,000 W; Efficiency 80%; Voltage Regulation <0.005%; Current Regulation <0.1%

XP Glassman’s LH Open Stack Series of high voltage AC/DC power supplies are sophisticated 4 or 8 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 12 to 20 kW depending on the maximum DC voltage.

LH Open Stack 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 231.1 mm height x 636.5 mm depth. The remote-control unit size is 132.5 mm height x 482.6 mm width x 168.3 mm depth.

The LH Open Stack 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 LH Open Stack 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 LH Open Stack 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 LH Open Stack Series include 7.6 m of detachable interconnect cables, null modem cable and USB cable.

The LH Open Stack Series supplies, when configured with the 400 VAC input option, are fully compliant with the following European directives:

EN61010/ IEC61010, Safety
EN61000-6-4, Conducted and Radiated Emissions

EY Series High Voltage AC/DC Power Supplies

Input Voltage 198-264 VAC; Max. Output Voltage 1-60 kVDC; Max. Power 1,200 W; Efficiency >85%; Voltage Regulation <0.005%; Current Regulation <0.1% XP Glassman’s EY Series of 1200 W high voltage AC/DC power supplies feature flexible embedded controls with low ripple and noise. They are air insulated, fast response, 2U rack-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 EY 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 EY Series’ high voltage output is inhibited for a short period after each load arc to help extinguish the arc. Typically, ripple is less than 0.02% RMS of rated voltage at full load. Off-the-line pulse-width modulation (PWM) provides high efficiency and a reduced parts count for improved reliability. Front-panel digital encoders provide high-resolution local adjustment of voltage and current program. Integral RS-232, USB and optional Ethernet communications provide remote control program and monitor. The EY 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 rear panel switch allows selection of either constant-current or current-trip operation. Thermostats and fan RPM sensing shut down the power supply due to over-temperature or reduced fan speeds.
