    • TRACKING MODE

      Two channels can be controlled at once.

      If single channel power supply was supplied for each producer when it comes to your company’s mass production system, replace it with the power supply in two channels that supports our company’s tracking mode!
      There is no need to set up two channels’ voltage and current which is cumbersome.
      Instead, pressing simply one button, the tracking mode button can set up two channels in the same way using only one setting for the voltage, current and all the functions.

    • STORE & RECALL

      Save and Recall Voltage and Current set by user easily

      OPE Series can store and recall the voltage and current set by user.
      Even when a user is not an engineer, the user can use it easily for the production, product inspection, reliability test etc., with the Store and Recall function that set up and stored in advance.
