Description

EL30AC/DCSRS+IT3RS | Regenerative AC load & DC source/sink, 30 kW, with integrated IT30-RS transformer, 7U rack

The Cinergia EL 30 AC/DC SiC-RS+IT30-RS combines the powerful, regenerative technology of the Cinergia rack devices with an integrated isolation transformer. This offers maximum electrical safety, galvanic isolation and the highest precision in research, development and production tests. By using the latest SiC power semiconductors, the system achieves high efficiency, fast response times and a compact 19" design.

Typical applications

  • Laboratory and research environments: Safe separation of mains and DUT for sensitive measurement setups
  • Electromobility: AC/DC charging infrastructure tests, V2G/V2X tests with galvanic decoupling
  • Battery and storage technology: charge/discharge cycles, battery emulation with safe isolation
  • Power-Hardware-in-the-Loop (P-HiL): Power amplifier operation with protection against feedback to the grid
  • Industrial & Aerospace: Safety-critical EoL test benches, mains and device qualification

Operation & integration

Like all models in the EL AC/DC SiC-RS series, the IT3RS variant also features an intuitive 7" touch display for local control, sequence programming, plot and datalog functions. The device can be flexibly integrated into automated test environments via MODBUS/TCP communication and analog/digital I/Os. The integrated transformer enables a completely galvanically isolated mains and DUT side, eliminating the need for additional external isolating transformers.

Model focus: EL 30 AC/DC SiC-RS + IT30-RS

The EL 30 + IT30-RS is the most powerful model in the series with an integrated isolation module. It is aimed at users who require maximum power and safe electrical isolation at the same time - ideal for high-voltage, charging and battery tests in the laboratory or production environment.

  • Nominal power: 30 kVA/kW (AC/DC)
  • Nominal current: 44 Arms (AC), ±44 A per DC channel
  • Size & Weight: 7U (≈ 715 × 440 × 310 mm), increased weight due to transformer
  • Galvanic isolation: integrated isolation transformer (IT3RS) between mains and load/source
  • Operating modes: AC-CC/CP/Impedance (CZ) incl. harmonic tests; DC-CV/CC/CP/CR; optional battery & PV emulation
  • Regeneration: full regeneration with high efficiency even with isolated grid path
  • 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) Isolation Height Typical application
EL 30 AC/DC SiC-RS 30 kVA/kW 44 Arms ±44 A No - directly grid-connected 7U High power tests with backfeed
EL 30 AC/DC SiC-RS + IT30-RS 30 kVA/kW 44 Arms ±44 A Yes - integrated isolation transformer 7U (slightly increased weight) Lab, safety & Measurement applications with galvanic isolation

Conclusion: The EL 30 + IT30-RS combines the full performance and regenerative capability of the standard EL 30 with an integrated isolation transformer. This makes it the ideal solution for safety-critical testing tasks in which system perturbations and earth potential differences must be excluded.

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
  • Integrated isolation transformer (IT30-RS) for galvanic isolation between mains and DUT
  • Energy feedback into the mains to reduce energy consumption and waste heat
  • 19" rack format (7U, depth approx. 715 mm) - compact, modular and scalable
  • Local operation via 7" touch display with sequencer, plot & data logging (CSV)
  • Open MODBUS/TCP interface and analog/digital I/Os for test bench integration
  • AC functions: current, power, impedance modes; harmonic & interharmonic tests up to 50th order; THDi < impedance tests. order; THDi < 2 %
  • DC functions: CV/CC/CP/CR; optional battery test & PV panel emulation
  • Multichannel: 3 independent DC channels (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 operation: Parallel connection and serial configuration for power scaling
  • Extensive protection functions (overcurrent, overload, short circuit, 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)
