产品功能

Up to 50kHz high speed for voltage and current measurements
Dynamic mode as up to 25kHz in continuous transient operation: The transient test allows switching between two different load values. The function is used to test the dynamic characteristic of power supply (See photo section)
CR-LED function: Unique LED mode can provide LED driver test and can be used in LED power simulation. The LED constant power output waveform usually has large current ripple. This is because of the ripple, traditional CR mode can’t simulate the actual characteristic of LED driver, its testing current and voltage will shake. Based on traditional CR mode, CR-LED mode adds the setting item of diode break-over voltage. Only when the input voltage is above the set value, will the DC load start to work. Thus, the IT8800 Series can simulate the actual characteristic of LED
OCP & OPP tests: OCP and OPP test functions are particularly suitable for over-circuit and over-power point tests of products such as lithium battery protection module and power module. Through built-in OCP and OPP functions, the user can set such parameters as the initial current, cutoff current, step current, lasting time of each step current and the voltage drop value for judgment of protection of built-in OCP program for test. This will finally help users to automatically obtain over-current or over-power protection point and to judge if it is within the scope. The user can use it for design validation and production line system to save test time and improve test efficiency (See photo section)
Automatic test function: The IT8800 Series auto-test function can simulate many kinds of testing. It totally can edit 10 test files, and can make connection between one file and another. Also you can choose the condition to stop the test: stop when testing pass or fail. Its adjustable current speed rate of rising and falling can make auto-test simulate various kinds of test waveform
List mode: Not limited to just switching between two levels, the List mode helps you generate more complex sequences of input changes with several different levels (See photo section)
Adjustable rising/falling speed of current by List mode: List mode allows you to generate a complex current sequence. Moreover, the mode change can be synchronized with an internal or external signal, to accomplish dynamic and precise test. A list file includes following parameters: file name, step counts (range 2-84), time width of single step (0.00002s+600s), step value and slope. The LIST function can make many kinds of complex sequences, to meet complicated test requirements. The slope range is 0.0001A/µs -5A/µs in max (See photo section)
Voltage rising/falling time test: The IT8800 Series provide unique measurement function to test voltage rising/falling time. It can calculate the time from one voltage to another voltage without the need of oscilloscope
Current monitoring function: The IT8800 Series allow the users to monitor actual current through I-monitor terminal. Users could connect an oscilloscope to observe the actual current. It will generate at 0-10V analog signal to represent to 0-100% rated current of the front panel
Support Living and Latch modes: The IT8800 Series support with loading voltage setting and it offers two kinds of load modes. Choosing Living means working goes after status. When choosing Latch, it means work load point latch with loading status. It can meet different test requirements (See photo section)
Battery discharge test function: The IT8800 Series test the battery capability in CC mode. Make a program to set the stop conditions. There are three stop conditions can be chosen: stop voltage, stop capacity and stop timer. The discharge process of electronic load is terminated if the system checks the battery reaches the specified value or under an insecurity state. In testing procedure, the battery voltage, discharge current, discharge time and discharged capability will display on the front panel (See photo section)
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
