Technical Data

Description

EL 30 AC/DC SIC-RS | Regenerative AC load & DC source/sink, 30 kW, 7U rack

The Cinergia EL AC/DC SiC-RS rack series is a highly dynamic, bidirectional test platform for research, validation and end-of-line test benches. Thanks to state-of-the-art SiC power semiconductors, it offers very high efficiency, short switching times and a compact 19" design (7U). The devices operate in four quadrants as a regenerative AC electronic load and as a regenerative DC source/sink - including feeding energy back into the grid to reduce operating and installation costs.

Typical applications

  • Electromobility: EVSE/OBC tests (AC/DC), V2G/V2X scenarios, charging logic & communication
  • Smart grids & DER: Grid emulation, grid recovery, load flow and quality tests
  • Energy Storage & Battery: Battery tests, cycles and emulation (multi-channel)
  • Power HiL/PHiL: Use as a power amplifier with low delay
  • Photovoltaics: PV string/panel emulation with irradiance/temperature profiles
  • Aerospace & industry: R&D, verification and EoL test benches

Operation & integration

The series relies on a 7" touch user interface for local control (start/stop, sequences, plotting & data logging). Open MODBUS/TCP, analog/digital I/Os (BNC/DB15) and master/slave operation are available for integration into test benches. The 19" rack-compatible design (depth approx. 715 mm) enables easy integration into existing test environments.


Model focus: EL 30 AC/DC SiC-RS

The EL 30 is the most powerful model in the compact rack series and is aimed at demanding test applications that require higher power reserves or longer load profiles - without compromising on precision or efficiency.

  • Nominal power: 30 kVA/kW (AC/DC)
  • Nominal current: 44 Arms (AC), ±44 A per DC channel
  • Shape & Weight: 7U (approx. 715 × 440 × 310 mm), approx. 50 kg
  • Channel configuration (DC): 3× unipolar (2Q) independent or 1× bipolar (4Q)
  • Operating modes: AC-CC/CP/Impedance (CZ) incl. harmonic tests; DC-CV/CC/CP/CR; optional battery test/emu and PV emu
  • Regeneration: full regeneration with very high efficiency
  • Grid side: 3×400 V~ (option 3×480 V~), PF > 0.98, THDi < 2 % at rated power

Comparison within the series

Model Nominal power (AC/DC) AC-current (RMS) DC current (per channel) Dimensions / height Weight Typical use
EL 22.5 22.5 kVA/kW 44 Arms ±44 A 715 × 440 × 310 mm (7U) ≈ 50 kg Laboratory, validation, EoL with medium power
EL 30 30 kVA/kW 44 Arms ±44 A 715 × 440 × 310 mm (7U) ≈ 50 kg Higher power reserves, Long-term and stress tests

Conclusion: The EL 30 offers the same compact design and flexibility as the EL 22.5, but delivers 33 % more output power. This makes it ideal for applications where longer or more intensive load cycles are required - for example in e-mobility development or grid simulation.


Product features of the series:

  • Four-quadrant operation: regenerative AC load & regenerative DC source/sink in one device
  • SiC technology for high switching frequencies, fast transients and above-average efficiency
  • Energy feedback into the grid to reduce energy consumption, waste heat and installation costs
  • 19" rack format, 7U, deep ~715 mm - easy to integrate and scalable
  • Local operation via 7" touch display incl. Sequencer, plotting and data logging (CSV)
  • Open MODBUS/TCP interface, analog/digital I/Os, emergency stop integration
  • AC functions: current, power, impedance mode; harmonic, interharmonic and HF excitation up to 50th order; THDi < THDi < interharmonic and HF excitation up to 50th order. order; THDi < 2 % (nominal load)
  • DC functions: CV/CC/CP/CR; optional battery test/emulation and PV panel emulation
  • Multichannel: 3 independent DC channels (unipolar 2Q) or 1 bipolar channel (4Q)
  • Voltage ranges: DC up to 800 V (unipolar 2Q) resp. ±380 V (bipolar 4Q)
  • Mains side: 3×400 V~ (option 3×480 V~), power factor > 0.98
  • Master/slave: Parallel connection (AC/DC) as well as serial/serial-parallel DC configurations for power scaling
  • Extensive protection functions (over/short circuit, overload, watchdog, heartbeat, configurable limits)
  • Certifications: CE, IEC 61010-1 (safety), EN-61326-1 (EMC), RoHS/REACH
  • Quiet operation with forced cooling (< 55 dB @ 1 m)
