Description

EL+30 VHF | Regenerative HF load, AC, 27 kW, HF 360 - 900 Hz, platform: ePLUS; transformer: without

The EL+ vHF series was specially developed for avionics applications and offers a feedback-capable, bidirectional load platform for high-frequency power grids from 360-900 Hz. It enables the precise simulation of linear and non-linear loads as well as grid-connected devices - with high dynamics, reproducible results and maximum energy efficiency thanks to regenerative feedback.

General features

  • Bidirectional & regenerative: energy consumption and feed-in, significant reduction in energy requirements.
  • Clean mains input: THDi < 3 % and power factor > 0.98 at rated power.
  • HF operation 360-900 Hz: ideal for emulating 400 Hz on-board systems and variable frequency.
  • Power range: five models from 15 kW to 50 kW, switchable in parallel for higher powers.
  • Fine control & dynamics: fast transients, harmonic generation up to 50th order (per phase incl. freely selectable). order (per phase incl. freely selectable harmonics), independent phase configuration.
  • Versatile operating modes: constant current (CC), constant power/apparent power (CP/CS), impedance (CZ) as well as step/interference profile tests with µs resolution.
  • Ease of use & openness: 4.3" touch, Modbus TCP/Ethernet, optional analog/digital I/Os, LabVIEW support.
  • Master/Slave: Fibre optic connection of multiple devices, simple scaling from the software.
  • Safety & protection: Emergency stop, interlock, freely parameterizable alarms and thresholds.

Typical applications of the series include testing of aircraft generators with variable frequency, simulation of on-board consumers (linear and non-linear), anti-islanding tests on grid-connected converters, the generation of defined interference profiles (flicker, voltage dips) and characteristic power and impedance testing in AC systems in aviation technology.

Model in focus: EL+30 vHF

The EL+30 vHF is the medium power model in the series and combines high current carrying capacity with a compact design. It is the ideal solution for test benches with increased power requirements, where precise regulation, stability and efficiency are crucial - for example in the qualification of 400 Hz systems, power converters and avionics consumers.

Power data & suitability

  • Nominal power: 27 kW
  • Nominal AC current (rms): 40 A (3-channel) / 120 A (1-channel)
  • Dimensions (W×D×H): 450 × 770 × 1100 mm
  • Weight: approx. 175 kg
  • HF range: 360-900 Hz (identical for all models)

Comparison within the series

Compared to the smaller models EL+15 vHF (15 kW) and EL+20 vHF (20 kW), the EL+30 vHF offers a significantly higher current and power reserve. Compared to the larger variants EL+40 vHF (40 kW) and EL+50 vHF (50 kW), it remains more compact and energy-efficient, making it a versatile solution for laboratory and development environments.

  • Advantages: Extended performance in a compact size - ideal for medium to high avionics loads.
  • Same platform features: identical software, control modes, frequency range and protection functions as all vHF models.
  • Scalability: combinable in master/slave mode for easy power expansion.

Most important technical specifications of the series

  • Mains side (input): 3×400 Vrms + N + PE, voltage range +15 % / -20 %, 48-62 Hz
  • Mains quality: THDi < 3 % at rated power, power factor > 0.98
  • Efficiency (typ.): ≥ 91 % (depending on model)
  • Output (HF-AC, EUT side): 1- or 3-phase operation; permissible voltage up to ±400 Vpk; approx. 35-277 Vrms ph-N / 35-480 Vrms ph-ph; option "HV" up to approx. 295/510 Vrms
  • Frequency range (HF): 360-900 Hz
  • Modes: CC (program current), CP/CS (power/apparent power), CZ (impedance R/L/C), steps/disturbance profiles
  • Dynamics (typ.): rise times in the ms range, setpoint resolution 10 mA/1 W
  • Harmonics: generation up to 50th order per phase incl. freely selectable harmonics; non-linear load emulation
  • Phase configuration: independent settings per phase (current, phase angle, harmonic content)
  • Overload capacity: up to 125 %/10 min, 150 %/1 min, 200 %/2 s (depending on model)
  • User interface & interfaces: 4.3" touch, Modbus TCP/Ethernet, optional RS485/CAN/RS232 gateways, analog/digital I/Os
  • Master/Slave: fiber optic network of up to 8 units (AC parallel; DC parallel/serial/serial-parallel depending on mode)
  • Safety & measurement: emergency stop, interlock, freely configurable alarms; measured values (U/I/P rms, frequency, temperatures, logging)
  • Environment: 5-40 °C, up to 95 % r. H. (non-condensing), forced ventilation
  • Acoustics (typ.): < 52 dB(A) for models up to 60 kW
  • Dimensions/weight (typ. Cabinet up to 60 kW): approx. 450 × 770 × 1100 mm; ~175 kg
  • Standards/Compliance: CE, EN-50178/EN-62040-1 (safety), EN-62040-2 (EMC), RoHS
