      2) Current capacity test
      3) Power discharging test, Battery, Capacitor, Charging Devices.

    • Regardless of the input voltage, it always maintains its constant voltage.

      Areas with

      1) Power test, Adaptor, Various DC Power, etc
      2) Power supply CC Circuit test

       

    •  

      Taking the load current to resist input voltage of Power supply.

      Areas with

      1) Analysis Power supply characteristic
      2) Delay starting up Power supply
      3) Power resistor simulation


    • Dynamic Mode allows voltage & current to change in high-speed.
      Users are able to set 0.1ms ~ 4s 1 Cycle Time and 6~0.1ms ~4s 1 Cycle Time and 6~94% Cycle Duty to make pulse that user wants.

      Areas with

      1) Inrush load experiment Inrush of high-speed encounter to cope with the cold load power inrush test.
      2) The instantaneous current capacity testing
