What is the Power Measurement range?


Why use an electronic load rather than a fixed value power resistor?

A fixed value power resistor is suitable for applications that require no closed loop control, however, they can present many limitations when testing power sources. Electronic loads have the ability to emulate various scenarios and actual devices that connect to your power source, whilst providing higher flexibility by allowing you to sink various levels of power and arbitrary profiles. Electronic loads reduce test time and cost by easily adapting to continuous changes in device test requirements, making them a highly effective solution to test power devices.
