■ Water-Cooled High Voltage Power Supplies:
Lic engineering is specialized in the compact & high power Water-Cooled high voltage power supply & CO2 laser power supplies. It’s Super Pulse and Ballastless technologies are the original development by a Lic engineer in the early 1980s for the CO2 surgical laser systems. Lic’s Water-Cooled Power Supply is very compact but powerful.

We put Power in the power supply and took away the large size!!

• Unique Core Design:
  The output transformers are very thin--but powerful-- allowing a low, minimum operating temperature. The core cooling method is also carefully designed. Both of these characteristics result in one of the most compact switch-mode CO2 laser power supply available in the world today.
• Series Resonant Topology:
  From its beginning, the basis of our switch mode CO2 laser power supply uses Series Resonant Topology with a zero-current switching. Our AZCS (Auto-Zero-Current Switching) used for our CSF-25000 series and our ideally matched resonant components enable IGBT to switch at almost zero current over the entire operating range. When AC voltage, or load impedance is changed, the AZCS automatically finds an optimum operating condition.
• Thin flat & dry insulation:
  These make our power supplies high efficient, reliable, and compact, eliminating the problems accompanied with an improperly designed oil-filled construction.

■ True Sine Wave Inverter:
With 27 years of technology accumulation in power electronics industry, Lic developed its first sine wave inverter. Its patent pending zero-current topology enables the inverter, very compact, light weight, and high efficiency without sacrificing the simplicity and low material cost.
