The LDG-XXXX/QCW High Power QCW Laser Diode Driver features a built oscilloscope and a huge capacitor bank providing up to 10KW CW/1MW QCW with a very stable and precise current
- Powerful QCW Capacitor Charging Power Supply: Up to 1MW QCW, communicates closely by the feedback circuit to keep a stable and precise constant current to the load
- Huge Capacitor Bank: up to several hundred Farad for the Best Current Droop at High Current & Long Pulse
- Ultar-Wide Pulse at huge current up to 60mseconds at 1.3KA
- High Power/High Speed LD Driver: 500V/500A at 100ns rise/fall time
- Competitive Price
Key Features
- Built in Oscilloscope: Don’t need any expensive instruments to measure & watch the LD waveforms!
- 1.3KA/60ms cuurent pulse with 1% Current Droop!!
- Non-USB Operation: Good for the special areas where any computers devices are not allowable
- High Performance Digital Scope Standard: 3.5ns/100MHz monitor scope as standard, 1.75ns/200MHz, and 0.7ns/500MHz scope as an option
- High speed current sensing device to sense and display in real time. Output current is sampling and regulated every micro-seconds. This technique guarantees the precise constant current control for customer’s wide range of Laser diodes.
