The EAC-4Q-GS series is a high-performance and multifunctional grid simulator that utilizes advanced PWM technology. This highly flexible configurable system offers output powers from 30 kVA to 500 kVA per single system. By using master/slave configurations with up to four systems, a total power of up to 2 MVA can be achieved. Furthermore, customer-specific solutions with capacities up to 4 MVA and more are available. The standard voltage is 300 Vrms L-N, but can optionally be extended.

The bidirectional source can be used both as a grid simulator and as a regenerative AC load, offering comprehensive interface options for flexible control. Standard models include 45, 60, 120, 180, 250, 300, and 500 kVA with currents of up to 757 A per phase. A touch panel and GUI software enable efficient operation and monitoring.
