LK Series 3 kW Regulated High Voltage DC Power Supplies

Product catalog summary

Overview: The LK Series are sophisticated 3 kW high voltage DC power supplies designed for applications requiring low ripple and noise. They are air-insulated, fast response units with tight regulation, compliant with CE standards and featuring power factor correction to >0.995.

Specifications: The power supplies offer a voltage range from 40 kV to 100 kV, with models available for different voltage and current combinations. They operate with an input of 198 - 264 V RMS, single-phase, and have an efficiency greater than 85% at full load. The power factor is greater than 0.995, and they feature low ripple (<0.025% RMS) and tight voltage regulation (better than 0.005%).

Features: Key features include active power factor correction, arc quench and sensing capabilities, pulse-width modulation for high efficiency, and constant voltage/current operation. The units are air-insulated, avoiding the use of oil or encapsulation, and include redundant thermal overload protection.

Protection and Safety: The LK Series includes automatic current regulation to protect against overloads, arcs, and short circuits. Thermal switches and RPM sensing fans provide protection against thermal overload. The arc quench feature inhibits HV output after each arc, and arc sensing helps manage load arcing problems.

Control and Monitoring: The front panel includes controls for voltage and current settings, with digital meters for output levels. The rear panel provides AC power entry, fuses, and remote interface terminals for safety interlock and monitoring signals. Remote HV enable/disable is supported.

Options and Accessories: Options include dual analog panel meters, zero start interlock, and slow start ramp. Accessories include a detachable high voltage coaxial cable. Models are available with positive, negative, or reversible polarity.

Compliance: The LK Series complies with EN61000-3-2 for harmonics and the European Harmonized EMI Directive EN50082-2, as well as the European Low Voltage Directive 73/23/EEC.
