Laser Diode Driver, High Power Precision, 20A, 4V, USB & GPIB, 220 VAC [Discontinued]

The LDX-32420 High Power Precision Laser Diode Driver is a 10A/20A microprocessor-based current source that offers a high stability, low noise output and integrated laser diode protection circuits. In addition to precision current control, the LDX-32420 Precision Laser Diode Driver is loaded with standard features such as dual current ranges, constant power control, fine/coarse set point control, four-wire forward voltage measurement, and external modulation capability.
For automated testing applications in an R&D or production environment, remote operation is easily accomplished through the GPIB/IEEE-488 or USB remote interface. For virtual instrument programming, LabVIEW® instrument drivers are available free of charge. LabVIEW instrument drivers can be downloaded from the Literature and Downloads tab on this page.
