LQ Series 10 kW - 50 kW Regulated High Voltage DC Power Supplies

Product catalog summary

Overview: The LQ Series is a family of sophisticated 10 kW high voltage DC power supplies, offering outputs from 1 kV to 12 kV. These units are designed for rack mounting and are compliant with CE and Semi S2-93 standards. They feature low ripple and noise, air insulation, and fast response with tight regulation.

Compliance: The power supplies comply with the European Harmonized EMI Directive EN50082-2 and the European Low Voltage Directive 73/23/EEC.

Key Features:

Arc Quench and Arc Count: These features help manage and mitigate load arcs by inhibiting HV output temporarily and counting arcs to prevent system faults.
Pulse-Width Modulation: Enhances efficiency and reliability by reducing parts count.
Low Ripple: Maintains ripple below 0.1% RMS of rated voltage at full load.
Constant Voltage/Current Operation: Automatic crossover protects against overloads, arcs, and short circuits.
Thermal Overload Protection: Includes thermostats and fan RPM sensing to prevent overheating.
Tight Regulation: Voltage regulation is better than 0.05% for line and load variations; current regulation is better than 0.5%.

Specifications:

Input: 187 - 228 V RMS, three-phase, 48-63 Hz, with a maximum of 14.5 kVA at full load.
Efficiency: Typically greater than 85% at full load.
Output: Adjustable from 0 to rated voltage/current with high accuracy and stability.
Line and Load Regulation: Less than +/- 0.05% for input and load variations.
Ripple: Less than 0.1% +1V RMS of rated output voltage.
Temperature Range: Operating from -20 to +40°C, storage from -40 to +85°C.

Control and Monitoring:

Front Panel: Includes controls for voltage and current settings, HV on/off switches, and status indicators.
Rear Panel: Contains AC input connections, HV output, and interface connectors for remote control.
Remote Control Interface: Provides inputs for safety interlock and program signals, and outputs for monitoring and status.

Options and Models: Various models are available with different voltage and current ratings, and options such as zero start interlock and slow start ramp are offered.
