Industrial power supplies / AC mains simulators

AC grid simulators

100% fully regenerative to the grid

Digital grid simulators in 4-quadrant operation

Grid simulators allow the simulation of various grid conditions as well as the generation of grid faults and disturbances with which the regenerative devices under test can be evaluated.

The digital ACS series from the Swiss manufacturer Regatron is based on high-speed basic units with versatile intervention options and high system dynamics.

On the simulation side, the devices supply a three-phase AC voltage of 0 - 280V (350V can also be realized with output transformers) with an active neutral conductor. DC operation possible.

Digital AC grid simulators Made in Europe - your complete solution for research and development

In today's world, where the generation, transmission and distribution of electrical energy is of essential importance, security and quality of supply, play a central role. Our AC grid simulators made in Europe offer you the opportunity to set up all conceivable grid situations for research and simulation work on generating or regenerative electrical equipment and electrical systems. Find out more about the versatile applications and advantages of our products.

  • Electromagnetic compatibility testing

    Our modular AC grid simulators are ideal for investigating the electromagnetic compatibility (EMC) of electrical systems. By simulating various grid situations, potential faults and their effects can be identified and analyzed at an early stage.

    Grid connection behavior of electrical systems

    The analysis of the grid connection behavior of electrical systems is another important area of application for our digital AC grid simulators. They can be used to simulate the conditions under which systems are connected to the grid to ensure that they meet the requirements and operate reliably.

    Fault management

    Effective fault management is crucial for security of supply. Our AC grid simulators made in Europe make it possible to simulate faults in the grid and investigate their effects. This allows developing measures to avoid or minimize disruptions.

    Effects of geomagnetically induced currents

    Geomagnetically induced currents (GICs) can have a significant impact on the power grid. Our digital AC grid simulators can be used to simulate these currents and investigate their effects in order to develop appropriate protective measures.

  • Modular, expandable test setups

    Our AC grid simulators are equipped with programmable power amplifiers that can be adapted to different scenarios thanks to their modular design. This offers a practical alternative to conventional test setups, which are often complex and inflexible. Research institutes, testing laboratories, universities, industry and energy suppliers benefit equally from this flexibility.

  • Development and testing of onboard chargers

    Our AC grid simulators are used in the development, testing and adaptation of onboard chargers. They supply them with alternating current and simulate power grids from all over the world. This enables comprehensive testing and optimization of onboard chargers.

    Energy storage capacity of electric vehicles

    In the further development of energy grids, the energy storage capacity of electric vehicles must be taken into account in order to cover consumption peaks. Our grid simulators make it possible to test the support of the power grid by vehicle batteries, which can help to ensure a stable voltage. To test these functionalities, grid simulators and bidirectional power supply units are the first choice.

  • Modular expandable network simulators

    Our 4-quadrant network simulators are universal tools for all relevant grid anomaly test sequences. They allow energy flow in both directions at full rated power and are therefore ideal grid simulators for normal energy consumers as well as for energy-feeding elements such as grid-connected inverters. All relevant test procedures according to IEEE and VDE standards can be carried out. The high degree of programmability leaves room for later extensions of all kinds.

  • Efficient planning and implementation

    Our comprehensive service begins with a detailed analysis of your requirements and the creation of a customized concept. We offer you a complete solution from a single source, from the initial consultation to turnkey delivery. This ensures that you receive an optimal and fully integrated solution.

    High-quality production

    In its 4,000m2 high-tech building, the Swiss company Regatron ensures state-of-the-art production of your AC grid simulators, whether as individual units or as a turnkey cabinet solution. turnkey cabinet solution. By using the latest technology, we guarantee seamless production and reliable operation.

    Turnkey delivery and commissioning

    Our services do not end with consulting and design. We provide you with a turnkey solution that is ready for immediate use. On-site system training with a DUT of your choice is just as much a part of our services as lifetime support for questions during operation. So you can be sure that everything will run smoothly.
