Design Features

  • 30 kHz dynamic mode: Transient test function enables the load to periodically switch between two set levels (Level A and Level B). It can be used to test the transient
    characteristics of the DUT. The highest frequency can be set to 30 kHz. Besides, in the guide interface, you can configure parameters in the parameter configuration list and view the configuration diagram at the left of the configuration list in the real-time manner.
  • 5 A/μs current rising speed: Current rising speed is defined as the speed of transition from one setting to another. You can set the actual transition time from one setting to another by changing the current rising speed. Adjustable current rising speed: 0.001 A/μs to 5 A/μs.
  • Powerful list operation function: You can generate complex sequences by editing the setting value for each step, the dwell time, and slew rate (the slew rate can only be edited in CC mode) to meet the complex test demands.
  • Powerful waveform display function: The electronic load provides the waveform display function and supports the following operations for the waveform, such as pausing the waveform, recording the waveform, and capturing the waveform. Therefore, you can dynamically observe the trend of parameters changes.
  • Easy-to-use function of file storage and recalling: The load allows you to save different types of files to the internal and external memories. You can recall and read them when necessary.
  • Sound OVP/OCP/OPP/OTP/Reverse Voltage Protection: When OVP/OCP/OPP/OTP/reverse voltage protection occurs, the load will immediately turn off the input automatically and stop sinking. Then, a prompt message is displayed.
