The ActionPower PRE20 regenerative grid simulator is a powerful and versatile tool designed to meet the needs of a wide range of power testing applications. Combining a bidirectional programmable AC power supply with a feedback programmable AC load, the PRE20 is a comprehensive solution for industries focused on power system validation and grid simulations. The unit offers exceptional flexibility and efficiency, making it a go-to device for engineers and researchers working with inverters, converters, and other energy systems.

Versatile Testing Capabilities of the ActionPower PRE20

The ActionPower PRE20 regenerative grid simulator stands out due to its unique design, which allows it to function both as a power supply and as a load. This bidirectional capability can be easily switched via the panel or commands, offering seamless integration into testing workflows. When operating in load mode, the PRE20 delivers full four-quadrant loading, enabling the unit to recover 100% of the current back into the grid. This regenerative feature provides up to 91% feedback efficiency, making the PRE20 an environmentally friendly and cost-effective solution for power testing.

Another key feature of the ActionPower PRE20 regenerative grid simulator is its high voltage capabilities. The unit integrates up to 12 RLC network models, allowing for precise adjustments to simulate a variety of load characteristics. This makes it ideal for validating the performance of tested products under different impedances, as well as balanced and unbalanced three-phase load conditions. These capabilities are particularly useful when testing devices like PV inverters and power conversion systems, where accurate simulation of real-world grid conditions is crucial.

Optimized Testing for Inverters and Converters

The ActionPower PRE20 regenerative grid simulator is particularly effective for testing inverters and converters, with features that enable advanced testing like anti-islanding protection. Islanding is a phenomenon where a device continues to supply power to a local grid even during a grid failure, which can be dangerous. The PRE20 can simulate islanding conditions and automatically reduce the output voltage if the current or power exceeds preset limits, ensuring the safety of the tested device.

In addition, the PRE20 offers the ability to output peak values up to three times the rated current, which is useful for testing the surge capacity of inverters, converters, and other energy devices. With adjustable overcurrent protection delays, the ActionPower PRE20 regenerative grid simulator can accurately capture and record the surge current values, providing critical data for validating the durability of power systems under stress.

Comprehensive Grid Simulation for Various Applications

The ActionPower PRE20 regenerative grid simulator offers remarkable versatility in its applications. It is widely used in industries such as renewable energy, energy storage, and power conversion. Its bidirectional operation, regenerative power feedback, and flexible impedance models make it an essential tool for testing the performance of PV inverters, power conversion systems (PCS), and on-line UPS systems. Whether testing the efficiency of these devices or simulating grid disturbances, the PRE20 delivers precise, reliable results.

With its integration of up to 12 RLC network models and its ability to handle both balanced and unbalanced three-phase load conditions, the PRE20 is capable of simulating a wide variety of real-world grid scenarios. This flexibility ensures that the ActionPower PRE20 regenerative grid simulator is a valuable asset for testing and validating products under dynamic and challenging conditions.

Conclusion

The ActionPower PRE20 regenerative grid simulator is a state-of-the-art solution for power system testing, offering both a programmable AC power supply and a feedback AC load in a single, compact unit. With its regenerative capabilities, surge protection features, and flexible testing modes, the PRE20 is ideal for validating the performance, safety, and efficiency of inverters, converters, and power conversion systems. Whether conducting anti-islanding protection tests, simulating grid disturbances, or testing surge current capacities, the ActionPower PRE20 regenerative grid simulator provides a reliable and cost-effective way to ensure that energy systems meet the highest standards.
