LD-XXXX/QCW - QCW-Laser Diode Driver, 1KA, 1KV,CW-power to 25KW
- LD-XXXX/QCW is QCW high power laser diode drivers capable of 1MW(1KV/1KA) output power. LD-XXXX/QCW has many features such as a built in powerful capacitor charging power supply (average power to 25KW), accurate voltage/current tracking system, complete protection circuit, and high speed power current sensing / monitoring system.
- LIC Engineering's power electronics technologies accumulated in high speed power switching and capacitor charging power supply make LD-XXXX/QCW so compact (U3 - U7) but powerful (25KW) and high efficient product.
- The QCW time period is limited by both average powers and current droop specified. The maximum time can be several tens of ms.
- Charging capacitor up to 0.64 F
