Application examples of electronic loads

　　electronic loadFunction: It can simulate a load with parameters that can be changed arbitrarily, so as to test the performance of the power supply in various normal and extreme states. Batteries are also power sources, and discharge and discharge testing of batteries inevitably require discharge parameters to prevent damage to the battery, such as constant current discharge, constant power discharge, constant charge discharge, timed discharge, overvoltage self stop, etc. Of course, this requires electronic loads to have conditional triggering functions, such as timed triggering, cumulative value triggering, parameter threshold triggering, etc.

Application examples of electronic loads:

(1) LCD and other computer component manufacturers can use electronic loads to test and age their internal power supply modules

(2) Switching power supply manufacturers: Generally, electronic loads can achieve testing of parameters such as power stability, load stability, output voltage adjustment, and transient characteristics of DC power supplies. For power supplies with multiple outputs, a combination can be used for testing

(3) Adapter/charger manufacturer:

It is important to test the ability of the battery adapter to adjust the output voltage and current, as it will ensure proper power supply to the device and charging of the device battery. CC and CR working modes can be used for routine performance testing, and OCP and SHORT functions can be used to test the protective action of the product. The adjustment time and charging time of the charger can be measured by the load pulling time.

(4) Home appliance manufacturers: One version of home appliances will be powered by power modules, which require electronic loads for testing and aging.

(5) Other: In summary, testing what kind of product will require what kind of electronic load. For example, you can choose the electronic load that suits your product testing requirements based on the number of output channels, maximum high voltage, maximum current, maximum power, and what parameters need to be tested.

Electronic loads should have comprehensive protection functions. The protection function is divided into internal (electronic load) protection function and external (tested device) protection function. Internal protection includes: overvoltage protection, overcurrent protection, over power protection, voltage reverse and over temperature protection. External protection includes over-current protection, over-power protection, load voltage protection, and low voltage protection. The choice of electronic load should be one with true protection function.
