REGATRON's New Universal Regenerative DC Source Sink Series G5.UNV Offers Unrivaled Allrounder Capabilities.

5-in-1 Lab & Test Equipment: Battery Simulator, PV Simulator, Fuel-Cell Simulator, Battery Tester, and P-HIL Amplifier. A versatile and expandable DC power supply solution for a wide range of applications.

The regenerative, modular DC power supplies of the G5.UNV series are equipped with all necessary functions and software packages for a whole selection of common laboratory and test applications in industry and science. On the one hand, the new G5 series of bidirectional DC power supplies impresses with unique features: exceptional resolution and accuracy of voltage and current, very high control dynamics even at high power levels, a high auto-ranging factor of 3, and adjustable output filter time constants. On the other hand, powerful and field-proven software packages enable a focused and straightforward use in the following testing and research areas:

Battery Simulation by G5.UNV

  • Realistic simulation of the electro-chemical and electrical properties of a battery type in charge and discharge mode
  • Battery simulation models, long-term multi-channel data-logger, live viewer, data analyzer
  • Powerful real-time computing process

PV Simulation by G5.UNV

  • Realistic simulation of the properties of solar arrays, real-time processing of I-V curves, live viewer, data collector, reporting capabilities
  • Compliance with the efficiency measurement procedures for Maximum Power Point Tracking (MPPT) according to EN 50530
  • Definition of specific array curves, live-assessment of MPPT of the solar inverter under test, switchable earth leakage resistors
  • Super-fast real-time curve fit algorithm

Fuel-Cell Simulation by G5.UNV

  • Definition of the characeristic curves of fuel-cells and other linear/nonlinear electrical two-pole networks
  • Real-time simulation thanks to embedded processing on board the G5.UNV
  • Definition of the DC output voltage or current or power as a function of any of the input values IDC, UDC, or PDC by means of user-definable curves

Battery Testing by G5.UNV

  • Safe and versatile test solution for batteries and energy storage devices/systems. Maximum user safety and equipment protection.
  • The exceptional G5.RPP feature a) reliably prevents damage caused by accidental reverse polarity between battery and battery tester, b) provides overcurrent protection/soft start in case of unmatched voltages between battery and battery tester, and c) prevents deep discharge of the battery in the "voltage off" state.

G5.UNV as P-HIL Amplifier

  • In a typical P-HIL setup a fast real-time computer drives a power amplifier, allowing for dynamic modelling of (scaled) bidirectional DC systems.
  • G5.UNV is best suited as a power DC amplifier due to its high dynamics and the fast analog input port. Time delay of analog-in to DSP <50 μs.
  • The modular concept of the G5.UNV series is extremely beneficial to cover different applications with changing power/voltages.

The application possibilities of the G5.UNV series are very diverse. The power supplies are suitable for both bidirectional and unidirectional use, supplying or regenerating. Further application examples are: General purpose laboratory source or regenerative electronic load for testing and loading electric storage elements such as fuel-cells.

G5.UNV bidirectional DC power supplies range from 0...18 kW to 0...2400+ kW, 0...500 VDC to 0...3000 VDC. Not only is it possible to (automatically) reconfigure between parallel, series, and mixed operation, but also to expand the system with additional power supply units or to split it into smaller units. Therefore, the purchase of a REGATRON G5 power supply is a solid investment for the future.
