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 fl exibility 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 simplify test automation.
The LDT-5900 Series Temperature Controllers provide the finest balance of features for today’s temperature control needs in laser diode and component testing. In addition to wide temperature control range and uncompromising stability, these instruments combine a fully digital PID feedback loop with a precision 24-bit measurement system for the utmost capability in temperature control and measurement. Control and display temperature from -50°C to 250°C while delivering a low-noise, bipolar current (up to 10A) to the thermo-electric module. This unique temperature control topology offers fast settling time and temperature stability better than 0.005°C - ideal for laser diode applications requiring highly stable wavelength and optical power.
More Power for Faster Temperature Settling
The LDT-5980 provides 120W of output power for production applications that require fast temperature swings over a wide temperature range. The LDT-5980 , with its high voltage and current output, is designed specifically to drive the TECs used in these applications. Temperature setpoint resolution of 0.001°C gives you the ability to control to the exact temperature your application requires, and the PID control loop minimizes overshoot resulting in faster temperature settling times.
Uncompromising Thermal Stability
The LDT-5900 Series lets you easily control the temperature of your laser diode in one of four modes: (1) Constant Temperature (2) Constant Sensor (3) Constant Current or (4) Constant Voltage. Temperature stabilities of 0.005°C ensure device performance and highly reliable test measurements. With 0.005°C stability the LDT-5900 Series are ideal for R&D applications, eliminating mode hopping and significantly reducing RMS noise.
Auto-tune Function Saves You Effort
PID control loops provide unequaled temperature settling and stability performance but can be difficult and time consuming to optimize. Our new auto-tune function saves you effort by automatically determining PID control constants for your particular thermal load. If you change the load, you simply run the auto-tune again and let the LDT-5900 Series do the work of calculating the new control constants.
A Choice of Sensors for Your Application
In addition to a broad range of thermistors and RTDs, the LDT-5900 Series can accomodate IC temperature sensors for control feedback. By using the appropriate equation for the selected temperature sensor and the applicable calibration constants, residual errors of less than 0.005°C can be realized over wide temperature ranges. Sensor constants are easily entered via the front panel or GPIB.
Control and Measurement for Complex Testing
In addition to precision temperature control, the LDT-5900 Series provides four-wire voltage and sensor measurement for the most accurate characterization of laser diode module power consumption and reliable measurements. Independent heating and cooling current limits help achieve the fastest settling times, while protecting your device under all instrument modes. If your application requires checking the integrity of the TE device before and after installation into a module or device, there is no need for a separate instrument. The LDT-5900 Series provides an AC resistance measurement mode that outputs a low level AC current to the device under test and calculates its corresponding resistance.
Automated Temperature Control for Functional Test Systems
These LDT-5900 Series come standard with a high speed GPIB remote interface as well as RS-232 serial communication capability. For quick instrument response without a command program, a TTL trigger-in function steps the instrument through a preprogrammed series of temperature setpoints. A trigger-out signal indicates when the set point has been reached.
