Loads AC & DC

also known as current sinks, are devices that simulate current consumers.

Loads are essential components in various test and development applications where precise control and simulation of the electrical load is required.

Here you can find out exactly what AC/DC loads are, for which applications they are best used and what the differences are between conventional and regenerative loads.

AC loads

AC loads, or sinks, are used to test electrical devices and systems under real operating conditions by simulating AC loads. A powerful product example of this is the  G6000 series by Kewell.

Diese Lasten können in verschiedenen Leistungsbereichen und Frequenzen betrieben werden, um eine breite Palette von Anwendungen abzudecken. Dafür sind viele unterschiedliche Programmmodi und Einstellungen programmierbar.


Typical areas of application for AC loads

  • Testing of inverters
  • Development of electric vehicles and charging stations
  • Testing of power supplies and transformers

AC loads are widely used, particularly in the areas of power generation, renewable energies and the manufacture of electric vehicles.

DC loads

DC loads such as the IT800 (ITECH) are specially designed to test and simulate DC systems. They are often used to check the performance and stability of DC sources, batteries, solar systems and other direct current sources. DC loads are indispensable in areas such as electromobility, telecommunications, aerospace and in the research and development of energy storage systems.


  • Battery testing and characterisation
  • Testing of solar modules and photovoltaic systems
  • Testing of fuel cells

Conventional versus regenerative loads?

  • Conventional loads convert the electrical energy consumed into heat and dissipate it in the form of thermal energy. These loads are cost-effective and easy to construct. However, they are not suitable for applications in which energy is to be saved or recovered.
  • Regenerative loads feed the electrical energy consumed back into the power grid. These loads are more energy-efficient and environmentally friendly. This is clearly illustrated by the example of battery cycling, in which batteries are charged and discharged many times. Energy consumption is significantly reduced when regenerative loads are used.

Overall, AC and DC loads offer versatile solutions for testing and development tasks in various industrial sectors. By selecting the right type of loads, companies can increase efficiency, improve product quality and drive the development of innovative technologies.
