Siemens LGN 7621A Laser Tube High Voltage Power Supply

Siemens LGN 7621A Laser Tube High Voltage Power Supply delivers a regulated 1.25–1.75 kV DC output at up to 5 mA from a 110–220 VAC input. This compact high-voltage driver is designed to power a laser tube by providing the precise voltage and current required for stable light generation. The unit’s input supports 110–220 VAC mains, allowing operation in regions with different standard voltages, while the output provides a controlled kilovolt-range DC supply to the tube. With a fixed maximum current of 5 mA, it constrains the drive to the tube’s needs and helps maintain consistent emission characteristics. The LGN 7621A is suitable for integration in laser tube assemblies, laboratory instrumentation, and other equipment that relies on a dedicated laser-tube power source. Users should ensure proper electrical isolation, safe enclosure, and adherence to laser safety practices when integrating this supply with a tube, as with all laser hardware.
