LH Series 5 kW Regulated High Voltage DC Power Supplies

Product catalog summary

Overview: The LH Series is a family of sophisticated 5 kW high voltage DC power supplies ranging from 1 kV to 100 kV, designed for rack mounting. These units are CE and Semi S2-93 compliant, featuring 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 (Safety) Directive, 73/23/EEC.

Key Features:

Arc Quench and Sensing: Inhibits HV output after load arcs to extinguish them and senses arcs to prevent system faults.
Pulse-Width Modulation: Enhances efficiency and reliability by reducing parts count.
Low Ripple: Less than 0.05% RMS of rated voltage at full load.
Constant Voltage/Current Operation: Automatic crossover for protection against overloads, arcs, and short circuits.
Thermal Overload Protection: Uses thermostats and fan RPM sensing to prevent overheating.
Tight Regulation: Voltage regulation better than 0.005% for line variations and 0.01% for load variations.

Specifications:

Input: 187 - 264 V RMS, 3-phase, 48-63 Hz, with a maximum of 6500 VA at full load.
Efficiency: Typically greater than 85% at full load.
Output: Continuous and stable adjustment from 0 to rated voltage or current with high accuracy.
Protection: Includes automatic current regulation, thermal switches, RPM sensing fans, fuses, and surge-limiting resistors.
Environmental: Operating temperature from -20 to +40ºC, storage from -40 to +85ºC.

Models and Options: The series includes models with positive, negative, and reversible polarity, with various output voltages and currents. Options include different input voltages, dual analog panel meters, and RS-232 control.

Warranty: Standard power supplies have a three-year warranty, while OEM and modified units have a one-year warranty.
