LD-XXXX/QCW is high power laser diode driver

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.
