The Cinergia GE+ vAC/DC series comprises 13 models from 7.5 kW to 160 kW and offers "Same Power in AC and DC". Each device can freely specify grid characteristics such as voltage, frequency, phase angle and (inter)harmonics up to the 50th order per phase; THDi on the grid side < 3 % at cos φ > 0.98 ensures a clean feed-in. The 30 kHz control loop and extensive interference profiles (including IEC 61000-4-11/-13/-14/-28, LVRT, SEMI-F47) enable reproducible tests. Applications range from electromobility & charging infrastructure to energy storage, PV/PV emulation, smart grids and power HiL.
- Generation of global grids: 3-phase/1-phase/split-phase, independent phase parameters incl. harmonics & ramps.
- Disturbance & standard tests: Dips, flicker, frequency jumps, (inter-)harmonics; editor & ready-made IEC profiles (pre-compliance).
- DC multichannel: Up to three independent bidirectional DC channels (common ground), CV/CC/CP/CR modes, battery test/emulation & PV emulation optional.
- Regenerative & parallelizable: regenerative for energy recovery; master/slave via LWL for power/voltage increase.

Variant in focus: GE+ 40 vAC/DC
The GE+ 40 vAC/DC model offers a rated output of 40 kW in AC and DC and marks the entry into the high-performance range of the series. With its high current and dielectric strength, the device is ideal for demanding test applications in research, development and production - for example for power electronics, energy storage, vehicle electrical systems or charging infrastructure. In AC mode, the GE+ 40 vAC/DC delivers up to 58 A (3-channel) or 174 A (1-channel). In DC mode, ±58 A (3-channel) and ±174 A (1-channel) are available. The combination of high dynamics, precise control and regenerative capability makes this model particularly suitable for continuous test cycles and long-term tests under realistic mains conditions.
Comparison with the other models in the series
