ELZ Series Regenerative Electronic Load

  The ELZ Series Regenerative Electronic Load provides a high-power, fully regenerative solution for demanding 4-quadrant testing requirements. It is specifically engineered to handle utility-scale testing for inverters, energy storage systems, and modern grid infrastructure. With power levels starting at 30 kVA and scaling beyond 1.1 MVA, it meets the rigorous needs of both laboratory research and industrial-scale testing environments. Built with advanced regenerative technology, this series returns more than 90% of the consumed energy back to the local utility grid, significantly reducing operational costs and heat dissipation. The 4-quadrant operation allows for precise simulation of complex load conditions across DC and AC frequencies ranging from 15 to 1000 Hz. Its scalable cabinet design ensures that the system can grow alongside increasing power demands, providing a long-term testing solution. This series offers flexible output configurations, including 1-phase, 2-phase, and 3-phase modes to accommodate various international testing standards. Users can enhance system capabilities with an optional PHIL (Power Hardware-in-the-Loop) interface for real-time simulation and advanced grid research applications. Available base models include 30 kVA, 45 kVA, and 55 kVA units that can be combined to reach massive power throughput exceeding 1.1 MVA.

Regenerative Power Efficiency

The ELZ Series is designed with a focus on sustainability and cost-efficiency, featuring a regenerative capability of over 90%. By recycling energy back to the grid rather than dissipating it as heat, the system minimizes the need for extensive cooling infrastructure and reduces electricity costs. This makes it an ideal choice for high-duty cycle testing in energy storage and grid simulation applications.

Scalable 4-Quadrant Testing

This series supports full 4-quadrant operation, allowing for the simulation of both source and load characteristics across a wide frequency range from DC to 1000 Hz. The modular cabinet architecture enables the system to scale from 30 kVA to over 1.1 MVA, providing a future-proof solution for utility-scale inverter testing. With optional PHIL interfacing, it integrates seamlessly into complex hardware-in-the-loop simulation environments.
