Description

EL+50 vHF/DC -ITI | Regenerative HF AC/DC load, AC/DC 50 kW, AC HF 360 - 900 Hz, platform: ePLUS; transformer: IT internal

The EL+ vHF/DC ePlus series from CINERGIA is an advanced family of regenerative, bidirectional electronic loads specifically designed for avionics and aerospace test applications. It covers the frequency range of 360-900 Hz and allows the precise simulation of electrical loads in aircraft systems - for both AC and DC tests.

Thanks to the regenerative topology, the energy absorbed can be fed back into the grid, drastically reducing energy consumption and waste heat. The series is ideal for:

  • Testing aircraft generators and power distributors with variable frequency (360-900 Hz)
  • Characterization of engine starters, frequency converters and DC/DC converters
  • Simulation of highly dynamic loads, transient events and harmonic distortions
  • Emulation of real load profiles with complex power and reactive power behavior
  • Long-term and system tests with energy recovery for maximum efficiency

Focus on the EL50+ vHF/DC variant

The EL50+ vHF/DC is the most powerful model in the series with a rated output of 50 kW. It was developed for large-scale avionics test benches, integration systems and test centers that require maximum electrical power, precision and regenerative capability.

  • AC (EL-HF): 65 A RMS per phase in 3-channel operation or 195 A RMS in 1-channel operation
  • DC: ±50 A (3-channel) or ±150 A (1-channel)
  • Frequency range: 360-900 Hz in HF mode
  • Backfeed capable: Energy feedback into the grid with efficiency > 90 %

With its enormous current reserves, the EL50+ is predestined for system tests with high continuous load, grid-connected emulation and power-intensive transients. It offers maximum stability and precision even with complex, rapidly changing load profiles.

Comparison with the other models

The EL+ vHF/DC ePlus series comprises five scalable power levels. The EL50+ is at the top of the series and offers the highest power capacity with the same range of functions:

  • EL15+ vHF/DC: 15 kW - Compact entry-level model for basic testing
  • EL20+ vHF/DC: 20 kW - Mid-range model for standard applications
  • EL30+ vHF/DC: 27 kW - Powerful all-rounder for laboratory environments
  • EL40+ vHF/DC: 40 kW - High-performance variant for energy-intensive tests
  • EL50+ vHF/DC: 50 kW - top-of-the-range model for maximum power and system integration

Compared to the smaller models, the EL50+ offers significantly more current and voltage reserves, making it ideal for complex avionics distribution systems, multiphase test structures and high-current DC testing. At the same time, it remains fully compatible with all control and communication interfaces in the series.

Product features of the series:

  • High-frequency electronic load for avionics: 360-900 Hz
  • Bidirectional & regenerative: Regeneration into the grid to save energy
  • Clean grid current: THDi < 3 % and power factor > 0.98 at nominal load
  • Power levels: 15-50 kW, combinable in master/slave mode for higher power
  • Operating modes AC/HF: current, power, impedance mode with cos φ control
  • Operating modes DC: CV, CC, CP, CR; multi-channel capability with independent control
  • Harmonic & distortion: up to 50th harmonic freely configurable
  • . Harmonics freely configurable
  • Fast dynamics: Rise times typ. < 2 ms, ideal for transient tests
  • Sequence and step mode: deterministic test profiles with µs resolution
  • Mains connection: 3×400 V AC +N+PE, 48-62 Hz
  • HF voltage ranges (EL-HF): 35-277 Vrms ph-N or 35-480 Vrms ph-ph
  • DC range: up to 750 V (HV option up to 800 V)
  • Overload capacity: up to 200 % for short-term peak loads
  • Safety functions: Emergency stop, interlock, overvoltage/overcurrent protection, watchdog
  • Communication: 4.3″ touch display, analog/digital IOs, LAN Modbus-TCP, optional interfaces (RS485, CAN, RS232)
  • Options: Battery emulation, PV emulation, low-ripple mode, HV extension, anti-islanding
  • Mechanics: approx. 770×450×1100 mm, weight approx. 200 kg (depending on model)
