QC‑2000 High‑Current QCL Driver: Building upon the QC‑750 Touch, the QC‑2000 inherits all its advantages while achieving even higher integration. It integrates both current and temperature control drives in a single unit, and incorporates multiple output safety protection mechanisms to ensure secure QCL operation, including adjustable current clamping, output soft‑start, over‑voltage and under‑voltage protection, over‑temperature protection, and relay short‑circuit output protection. The user‑friendly interface, with an intuitive UI display, facilitates convenient operation and real‑time data monitoring. On this foundation, the QC‑2000 further supports higher current demands for the laser chip and provides enhanced TEC temperature‑control capability, meeting a broader range of customer application needs.
