ILX lightwave LDT-5910B temperature controller for laser diode. Very good condition.

The LDT-5900 Series Temperature Controllers deliver industry-leading precision, high power temperature control for laser diodes and fiber optic components. These controllers combine a fully adjustable PID control loop with digital PWM output current, ensuring fast, efficient, and precise temperature control from -50°C to 250°C. The LDT-5900 Series supports thermistor, IC and platinum resistive (RTD) sensors, selectable from the front panel or via GPIB interface, giving you maximum flexibility during system design and test. The LDT-5948 Precision Temperature Controller is ideal for internal TE control of laser diodes, with available output power of 60W. The LDT-5980 High Power Temperature Controller delivers 120W of power for external case control in L-I-V test applications and where wide-range test temperatures are required. Additional features like four-wire voltage and sensor measurements and an AC resistance measurement make these instruments perfect for characterizing TE modules during laser module development, testing, or assembly. Input and output triggers, standard GPIB control, and an auto-tune algorithm all work to accelerate and simplifytest automation.
