This unit
The ILX Lightwave CSM-39400M is a precision current source module engineered for integration into the LDC-3900 Modular Laser Diode Controller mainframe. It delivers stable, accurate current output essential for reliable laser diode operation in MOPA and tunable laser applications. The module operates in constant current and constant power modes, incorporates analog modulation capability, and features integrated laser diode protection circuits. Fully isolated from other modules, it eliminates ground loop issues while providing remote control via GPIB/IEEE-488.2 interface.
