The ILX Lightwave CSM-39437 is a 4-channel laser diode current source module engineered for integration into the LDC-3900 Modular Laser Diode Controller mainframe. This dual-function module operates as both a laser diode current source and Temperature Controlled (TEC) controller, delivering independent current sourcing across four channels with full electrical isolation to eliminate ground loops. Each channel functions independently, supporting flexible configuration for laser diode control and thermal management in multi-channel applications.
