Laser diode driver (QCW), model SF3xx

Switched mode laser power supply is designed for supplying diode array, which are used for pumping powerful solid or fiber lasers. Power supply is designed to the laboratory, educational, experimental and industrial applications. Additionally the power supply can be equipped with a LD thermal stabilization controller (TEC controller). Also it has current limit, duty cycle limit and safety interlocks. Could be modified by a customer's request for the optimal selection of parameters for a specific load.
