Usually you don´t test your power supply and you assume it is working well with your equipment. But what if not? Sometimes your equipment fails without any evident reason and it might be because your power supply is not sufficient for your application. We have a solution which helps you identify the problems with the power supple – electronic load.
With electronic load you can test your power supply or solar system and you can easily program the behavior of your device or even a bigger load. Elektro Automatik offers a wide range of electronic loads, even with energy recovering function.

Further information can be found in the electronic loads catalogue (14,5 MB). Upon request, we´re able to provide you with any product from the Electro Automatik catalogue (14,5 MB).
