Temperature Controller, Thermoelectric, ±5A, ±12V, 60W, GPIB & RS232
Model: LDT-5948
Product Series Overview
±5 A and ±10 A RS232/GPIB Thermoelectric Temperature ControllersThe LDT-5948 60W Thermoelectric Temperature Controller provides industry leading accuracy and precision for temperature control of laser diodes and other optoelectronic components. The LDT-5948 features a fully programmable digital PID control loop with auto tune feature. Standard features include four-wire voltage and sensor measurements as well as an AC resistance mode to characterize TE modules during development.
For automated testing the LDT-5948 features a GPIB user interface as well as input and output triggers. 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.
We offer a wide variety of precision laser diode mounts with plug and play compatibility with our laser diode instrumentation.
