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.
- Operation & integration: 4.3″ touch, open Modbus TCP interface (LAN), analog/digital I/Os, data acquisition.
Variant in focus: GE+ 20 vAC/DC
The GE+ 20 vAC/DC model extends the power range of the series to 20 kW, offering the ideal balance between compact design and high output power. With precise voltage and current regulation, this model is perfect for development and end-of-line testing of medium power inverters, storage and charging devices. In AC mode, the GE+ 20 vAC/DC delivers up to 29 A (3-channel) or 87 A (1-channel). In DC mode, ±29 A (3-channel) and ±87 A (1-channel) are available. The combination of dynamics, regenerative capability and high efficiency makes it a versatile solution for research facilities, test laboratories and industrial test systems.
Comparison with the other models in the series
- Power/scaling: The GE+ 20 vAC/DC marks the entry into the medium power class of the series and offers 33% more power than the 15 kW type - with almost the same footprint. Devices from 30 kW are designed more for multi-channel or continuous testing.
- Currents: With 29/87 A (AC) and ±29/±87 A (DC), the model already covers many typical test requirements for 10-20 kVA systems, including LVRT tests and DC simulations.
- Design: Compact cabinet housing measuring approx. 770 × 450 × 1100 mm at around 200 kg; designed for stationary laboratory installations and 19" integration.
- Functionality: Includes all core functions of the series - grid simulation, fault profiles, (inter)harmonics and programmable test sequences. Optionally expandable with battery/PV emulation.
