XP Glassman’s KR Series of 3 kW high voltage AC/DC power supplies feature flexible embedded controls with low ripple and noise. They are air insulated, fast response, 4U 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 2 kVDC through 0 to 100 kVDC.

The KR 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 KR 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% 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 KR 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.

Standard accessories for the KR Series include a detachable 2,4 m shielded high voltage coaxial output cable, line cord, null modem cable and USB cable.
