The CINERGIA EL+ vAC/DC ePlus series is a state-of-the-art, bidirectional and regenerative electronic load for AC/DC testing in laboratories, research facilities and industrial test environments. This series is considered one of the most versatile regenerative power sources on the market and combines high precision, energy efficiency and flexible control in one compact device. Thanks to its regenerative technology, it significantly reduces energy consumption and enables sustainable, cost-efficient test procedures. Thanks to a harmonic mains input with a THDi below 3% and a power factor above 0.98, it meets the highest demands on network quality and test technology.
The devices in the EL+ vAC/DC ePlus series offer a wide range of possible uses in modern energy and electrical engineering applications:
- Testing and development of components in smart grids and intelligent energy networks
- Testing and simulation of batteries, chargers, energy storage and DC systems
- Emulation of photovoltaic panels and performance of grid fault tests
- Use in HiL test systems (hardware-in-the-loop) for electric mobility
- .Loop) for electromobility and power electronics
- IEC-compliant testing of grid inverters and power supplies
- Research and development in avionics and in industrial test environments
Model description: EL+ 7.5 vAC/DC
The EL+ 7.5 vAC/DC model is the most compact device in the series and ideal for laboratories and test benches with limited space. It offers a rated power of 7.5 kW with a maximum AC current of 11 A (three-phase operation) or 33 A (single phase) and a DC current range of ±10 A / ±30 A. Despite its compact design (770 × 450 × 1100 mm, 155 kg), the device has the full functionality of the entire series. The EL+ 7.5 vAC/DC is bidirectional and regenerative, meaning that energy is fed back into the grid during testing - ideal for sustainable and energy-efficient laboratory environments. Compared to larger models such as the EL+ 20 or EL+ 60 vAC/DC (up to 54 kW), it offers an excellent balance between power, dynamics and efficiency. With response times of less than 1 ms and a resolution of 10 mV/10 mA, it guarantees high-precision results in dynamic tests. It can be controlled locally via a 4.3" touch display or via Ethernet (Modbus TCP). Thanks to its flexible three-channel configuration, the EL+ 7.5 is ideal for parallel or separate test paths. This makes it the ideal choice for test laboratories, developers and researchers looking for a high-performance, energy-efficient AC/DC load with precise control.
