High Power High Voltage Power Supply: Voltage to 25KV and Output Power to 25KW
Compact & High Efficiency DC Power Supply:
Liquid-Cooled 25KW with 97% Efficiency

Unique Core Design:The output transformers are very thin---that helps the heat conduction effectively to the water channel and keeps the H.V components’s operating temperature low. This results in the highly reliable and the most compact switch-mode CO2 laser power supply.

Series Resonant Topology:Since the first product was developed in early 1980s, Lic’s switch-mode CO2 laser power supply has used the series resonant topology, which make a switching current "sinusoidal", or ”zero-current switching” to make the switching loss minimal and is able to push a very high current into the secondary circuit in very short time. This zero-current switching technology makes Lic’s products high efficient, compact, and reliable power supply.

AZCS (Auto-Zero-Current Switching):AZCS (used for CSF-25000-series) enables  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.
