Rigol DL3031 electronic load
Details
The Rigol DL3031 electronic DC load belongs to the DL3000 series and has a power of up to 350W. The electronic load has 1 channel with an input voltage of 150V and an input current of 60A with a resolution of 1mA/1mV.
The Rigol DL3000 series is an affordable and comprehensive range of programmable loads. These devices offer a lot of functionality and possibilities for relatively little money. There are also several options to connect the electronic load to a PC for extensive logging. The electronic load is fully controllable, and extensive graphs and measurement results can be displayed. The loads have an internal memory to store measurement results locally and the ability to store the measurements on a USB drive. The main difference between the A and non-A versions is that the A version has the optional ports like LAN and digital I/O already included. On top of that the A versions have a higher resolution and a better slew rate. The non-A versions can also be upgraded to have a LAN and digital I/O port. With the digital I/O you can trigger the load, which can trigger another device like an oscilloscope or other products.
