The Thorlabs TED200C operation manual provides setup, safety, usage, maintenance and technical specifications for the thermoelectric temperature controller.
The TED200C Thermoelectric Temperature Controller from Thorlabs is a precise controller designed for laser diodes and detectors, offering temperature stabilization, noise reduction and wavelength tuning. It features a 5‑digit LED display, adjustable P‑I‑D control loops, and supports both NTC thermistors and IC temperature sensors.
This manual covers general information, safety precautions, unpacking, wiring, front‑panel operation, configuration of TEC current limits, temperature control settings, troubleshooting, and detailed technical data. Appendices include compliance declarations, warranty terms, end‑of‑life recycling policy and worldwide contact information.
