Description

EL+50 VHF | Regenerative HF load, AC, 50 kW, HF 360 - 900 Hz, platform: ePLUS; transformer: without

The EL+ vHF series was developed for the highest requirements in avionics and aerospace test engineering. As a regenerative, bidirectional electronic load, it offers precise simulation of electrical loads in high-frequency systems from 360-900 Hz. Thanks to its regenerative architecture, it enables energy-efficient tests with outstanding power quality and dynamic performance.

General features

  • Bidirectional & regenerative: Energy absorption and feedback into the grid with maximum efficiency.
  • Clean grid quality: THDi < 3 % and power factor > 0.98 at nominal load.
  • HF capability 360-900 Hz: ideal for simulating 400 Hz on-board grids and variable frequency.
  • Power range: models from 15 kW to 50 kW, with simple parallel connection to increase power.
  • Precise control: fast transients, harmonic generation up to 50th order, independent phase control.
  • Flexible operating modes: constant current (CC), constant power/apparent power (CP/CS), impedance (CZ), disturbance and profile tests.
  • Intuitive operation: 4.3" touch display, Modbus TCP/Ethernet, optional analog/digital interfaces, LabVIEW support.
  • Scalable system design: Master/slave operation possible via fiber optic connection.
  • Safety functions: Emergency stop, interlock, configurable alarms and protection thresholds.

The EL+ vHF series is suitable for power and network simulations in aviation technology, testing of aircraft generators and converters, simulation of on-board consumers as well as network qualification and interference simulation tests in research, development and quality assurance.

Model in focus: EL+50 vHF

The EL+50 vHF is the top model in the series and, with 50 kW rated power and up to 195 A current, provides an uncompromising solution for high-performance test benches. It is designed for applications where maximum load capacity, stability and precision are required - for example in the qualification of high-performance generators, converters or complex 400 Hz power grids.

Power data & suitability

  • Nominal power: 50 kW
  • Nominal AC current (rms): 65 A (3-channel) / 195 A (1-channel)
  • Dimensions (W×D×H): 450 × 770 × 1100 mm
  • Weight: approx. 200 kg
  • HF range: 360-900 Hz (as with all vHF models)

Comparison within the series

Compared to the smaller models (EL+15 vHF to EL+40 vHF), the EL+50 vHF offers the highest continuous power and current carrying capacity of the entire series. It is aimed at users who require maximum power density in an even more compact housing - especially for full system tests in avionics and industrial environments.

  • Advantages: maximum power, high current reserves and optimum voltage stability for the most demanding test conditions.
  • Common platform: same software, user interface and control algorithms as all models in the series.
  • Scalability: can be combined with other devices in master/slave mode for outputs above 400 kW.

Product features 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 %
  • Output (HF-AC, EUT side): 1- or 3-phase; permissible voltage up to ±400 Vpk; 35-277 Vrms ph-N / 35-480 Vrms ph-ph; "HV" option up to approx. 295/510 Vrms
  • Frequency range (HF): 360-900 Hz
  • Operating modes: CC (current), CP/CS (power/apparent power), CZ (impedance R/L/C), steps/disturbance profiles
  • Dynamics (typ.): Response times in the millisecond range, setpoint resolution 10 mA/1 W
  • Harmonic: Generation up to 50th order per phase, non-linear harmonics. order per phase, non-linear load simulation possible
  • Phase configuration: independent control per phase (amplitude, phase angle, harmonics)
  • Overload capability: up to 125 %/10 min, 150 %/1 min, 200 %/2 s
  • 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 devices (AC parallel; DC parallel/serial depending on mode)
  • Safety & measurement: Emergency stop, interlock, configurable alarms, measured values (U/I/P rms, frequency, temperatures, data logging)
  • Environment: 5-40 °C, up to 95 % r. H. (non-condensing), forced ventilation
  • Acoustics (typ.): < 52 dB(A)
  • Dimensions/weight: 450 × 770 × 1100 mm; ~200 kg
  • Standards & certifications: CE, EN-50178/EN-62040-1 (safety), EN-62040-2 (EMC), RoHS
