Introducing the RS PRO RS-KEL102 Programmable DC Electronic Load, a highly versatile device that is ideal for testing a range of power supplies. This highly reliable electronic load features high speed and accurate measurement, offering excellent measurement capability for an electronic component, battery, portable charger, and power supply that requires low to medium power consumption. It features an easy to read, large digital LCD display, alongside a user-friendly interface for easy operation, as well as a range of different operating modes to make testing easy across a range of different applications.

Electronic loads allow easy and quick simulation of various power states. They are useful for testing various power sources like batteries, inverters, converters and much more. These programmable devices are essential in ensuring various power supplies meet the required safety and compliance standards. Electronic loads are easier to use and provide a much higher output compared to fixed-resistors, offering various modes of control such as constant voltage, constant current, constant power, and constant resistance making them highly versatile and powerful instruments. They are often used in the following settings:

• Laboratory


• Research and Development facilities


• Aerospace


• Commercial Electronics

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.
