Looking forward Figure 9: Connecting electronic loads in series to expand voltage capacity is not recommended. Figure 10: Most electronic loads can be connected in parallel to expand the current capacity. An example connection diagram is shown. If there is an application that requires a larger operating current it is possible to connect electronic loads in parallel to expand their current capacity. When considering electronic loads for a new application find out the parallel connection capacity of the load. It may be necessary to purchase several units that meet the voltage requirement and connect them in parallel to meet the current requirements of the application (Figure 10). 2009EE_KikusuiElectroics.indd 1 From the examples shown above, we have seen that electronic loads in the market today have a wide range of functions that make testing DUTs more efficient and more effective. The capabilities of electronic loads allow them to be used in more demanding applications, but it also makes it more difficult for manufacturers to accurately represent the limitations of their products within the specification documentation. As a buyer, it is important to consider how an electronic load will meet the demands of your application and how easily it can be integrated into your lab as well as the operational costs of using the load. It is a good idea to use the manufacturers specification to narrow your search and then request to demo the remaining devices so you can be sure the load you choose will be suitable for your application. 8/4/20 7:21 AM SEPTEMBER 2020 EVALUATIONENGINEERING.COM 27http://www.kikusuiamerica.com http://www.EVALUATIONENGINEERING.COM
