Product Functions

  • Transient mode enables the module to periodically switch between two load levels, as might be required for testing power supplies. There are three different transient testing modes: continuous, pulse, and toggle (See photo section)
    • Continuous mode: The IT8500+ Series generate a repetitive pulse stream that toggles between two load levels.  Load could switch the state between two value settings, A/B (See photo section)
    • Pulse mode: The IT8500+ Series generate a transient pulse of programmable width when pulse transient operation is in effect.  The load will automatically switch to A level after maintaining A width time.  Then it will switch to B level.  The load will not switch to A level again until the instrument receives the pulse signal
    • Toggle mode: The IT8500+ Series switch between A level and B level when receiving a trigger signal after the transient operation is enabled
  • Automatic test function: The automatic test function of the IT8500+ Series is useful for simulating various tests and allows the user to edit up to 10 groups of testing files.  Each file has 10 steps and up to 100 files can be edited and saved into the EPROM.  The automatic test function needs to work compatible with the option IT-254 Keyboard Coordinating IT8500+ Series for Automatic Test Function
  • List mode allows you to generate a complex current sequence. Moreover, the mode change can be synchronized with an internal or external singal to accomplish dynamic and precise test which can save cost for users.  Users can edit step value, pulse width and slope sequence and meet a complex test request.  A list file includes following parameters:  file name step counts (range 2-84), time width of single step (0.00002s-3600s), step value and slope.  The edited list file can be recalled easily.  The DC load provides 7 nonvolatile regisers to save list files setting for recall later.  In the list mode, the DC start to run the list file once receiving a trigger signal, continue to run until end of the operation or receiving another trigger
  • Remote sense: When working in CC, CV, CP and CR mode, if the electronic load consumes a very large current, it will cause a voltage drop in the leads between the connected device and terminals of the electronic load. In order to ensure testing accuracy, the electronic load provides a pair of remote sensing terminals in the rear panel where users can sense the output terminal voltage of the connected device.  Users should set the electronic load in REMOTE SENSE mode before using this function.  By eliminating the effect of the voltage drop in the load leads, remote sensing provides greater accuracy by allowing the electronic load to regulate directly at the source’s output terminals
  • Battery mode: A battery test mode is provided that will measure the ampere*hour (A*hr) characteristic of a battery.  It measures the time it takes for a battery voltage to drop to a specified value while drawing a constant current from the battery.  There are three stop conditions for IT8500+ Series: time, capacity and voltage.  In addition, user can make any combination of stop conditions to achieve “ And ”, “ Or ” relationship.  When one or more stop conditions are satisfied, the test is ended and the discharging time, capacity in ampere*hours (A*hrs) of the battery is calculated and displayed on the front panel
