Main functions of electronic load

Electronic load is a kind of power electronic device based on power electronic technology, computer technology and automatic control technology. It can simulate various load characteristics, and has the advantages of flexible use and energy saving. Used to test the power supply, the power supply reliability test (aging discharge test), output characteristics test, to test its technical indicators and performance.

With the development of the electronic market, the requirements for electronic measuring instruments and food equipment are also constantly improving, in some LED drivers, power modules, chargers and other tests, will use the electronic load instrument, now this has become an essential test equipment.
For electronic load meter it has a lot of functions, the following to understand its various functions in detail.
1. Intelligent function. The intelligent function of the electronic load enables the load itself to automatically complete the product testing, and supports the dynamic testing of the sequence, and can continuously, pulse, flip and simulate the dynamic loading of any waveform.
2. Sequence function. In the complex application environment of electronic product development, product aging on production line, quality inspection and so on, electronic load edits a complex test sequence by itself to simulate various changes of load input and perform automatic test function. Especially in the overall test of power supply products, various test functions can be set as a sequence, with a variety of trigger sources for flexible automatic test.
3. Transient function. This function refers to the module of electronic load switching between two different values in the same function, which can be used to test the dynamic characteristics of the power supply and test the dynamic indicators of various power supplies.
The function can be operated in three modes: continuous, flip and pulse, and can quickly switch between the main value and the transient value. Meanwhile, it can flexibly set the slope of constant voltage, constant current and constant resistance rising and falling. Users can also easily change the slope to simulate complex load behavior.
4. Simulation programming function. When the power supply under test needs to carry out irregular dynamic loading (non-trapezoidal change), this function can be used to realize more simulation of the loading situation.
5. Internal status monitoring function. In the ATE test system, production line, quality inspection and other aspects, electronic load realized the function test based on multiple electronic loads, and monitor the actual test results, complete product quality control. The user can monitor the working state of the electronic load, monitor the difference between the actual value and the display value of the load and change the execution state when the load is dynamically fed through the monitoring signal terminal, and very conveniently use the external digital voltmeter or oscilloscope to monitor the voltage value and current value of the load.
6. Low voltage operation function. The low voltage operation function of electronic load is powerful, which can realize true zero voltage load and full current load voltage.
7. Protection function. Electronic load products all hardware to achieve internal (protection load) and external (protection detected equipment) protection, can be over voltage, over current, over power, over temperature, low voltage and voltage reverse and other aspects of effective protection.
