Check the listing for details. AVTECH AVO-8A-B Pulsed Laser Diode Driver 30V 10A 10uS-1Sec. Condition: Used. Listed at 1250.00 USD. This auction is for a AVTECH Model AVO-8A-B-ZYB Pulsed Laser Diode Driver Provides up to 30V at up to 10A current. Includes AVO-8A-B-ZYB-PG-N module, perhaps to supply higher voltage/current from an external DC power source. I am unsure of it's function. Cables included Please ask if you have any questions. Buyer to pay shipping. Thanks for looking The AVO-8 series of pulse generators is designed for pulsing laser diodes and other low impedance loads with rectangular pulses as high as 500 Amperes (or 50 Volts), pulse widths from 2 us to DC, and average output powers to several kilowatts. Model AVO-8D3-B is similar to the AVO-8C3-B, except that it operates up to 500A. It can operate at duty cycles to 35% at 200A to 250A, and 7% at 250A to 500A.
