G5.RSS Versatile DC Power Supply

The G5.RSS series is bidirectional regenerative and can operate in CV, CC, CP, or CR control modes with simulation of internal resistance in CV or internal conductance in CC mode. It is universally applicable and therefore suitable for all industrial and scientific applications in laboratories as well as on test benches and production lines. The modular and finely graded G5.RSS series is characterized by highly dynamic response times, 

adjustable filter time constants, and a wide current-voltage range with an auto-ranging factor 3. Optional software, programming, and communication interfaces as well as extended safety functions allow the G5.RSS power supplies to be  optimally adapted to special customer application requirements.

Applications and Features

The high accuracy and dynamics of the G5.RSS series, as well as the ability to easily change between different multi-unit configurations, make this series the ideal power supply solution for bidirectional R+D tasks and test bench applications such as testing of power conversion systems (PCS) or testing of converters for energy storage systems (ESS).

Various features such as switchable filter time constants and adjustable controller settings as well as the integrated powerful 8-channel digital scope assist the user to quickly and easily achieve optimal system behavior for a special application requirement.

Simplified and safe operation can be provided by pre-programmed overvoltage protection and digital fuses with immediate and I2t triggering. Different protection levels for different DUTs can be either programmed by the user’s automation test system via various interfaces or activated manually by digital input signals or even more conveniently wired to different switch positions.

The G5.RSS series also offers the possibility to store, edit, and recall any device configuration on board the power supply.

Parameterization example of a 36 kW, 1000 V, 108 A device: Set-value step current -97…97 A@333VDC in <50 μs with overshoot (top), in <200 μs w/o overshoot (bottom). This dynamic behavior is characteristic for all G5 devices.

G5.RSS Series as P-HIL Power Amplifier

Power-hardware-in-the-loop (P-HIL) simulation integrates physical hardware and software models in a closed-loop, offering versatile opportunities to investigate the behavior of complex systems at different parameter settings.
A typical PHIL setup includes a fast real-time computer driving a power amplifier. The G5.RSS series is best suited for this purpose due to its high dynamics and a fast analog port. Time analog-in to power output is typically 90 μs.

Modular and Easily Scalable Systems

The output of an individual power supply is in the range from 0…9 kW to 0…5000+ kW, up to 3000 VDC. The advantageous modularity of REGATRON power supply solutions allows the system to be easily adapted to ever-changing test requirements. It is possible to reconfigure between parallel, series, and mixed operation. Moreover, the system can be expanded with additional power supply units or may be split into smaller units.
Whether for single devices or powerful multi-device systems, REGATRON also offers turn-key cabinet solutions or project-specific system integration according to customer specifications.
Therefore, the purchase of a REGATRON power supply is a solid investment for the future.

Bidirectional DC power supply G5 modular system – REGATRON scalable programmable power supplies
Modular concept for easy power and voltage increase by parallel, series, and mixed operation. The parallel configuration allows even the operation of devices with different output power, e.g., 18, 36, and 54 kW modules, in one system.

Characteristics and Features in the Basic Scope of the G5.RSS Series

CV constant voltage

G5.Control allows complete and easy control of the power supply unit or entire master slave system and also offers a whole range of service functions. In addition to basic control, configuration and update functions, G5.Control has a powerful integrated 8-channel digital scope . The high-resolution real-time display of numerous internal system signals allows the engineer to optimize the overall system in a targeted manner. Different application specific settings of parameters for single devices or master slave systems can be saved on the devices and either recalled by G5.Control, an API or CAN message or digital I/O signals. Firmware updates can be carried out quickly and easily for individual units as well as for master slave systems with a single command. When handling support cases concerning the application of the power supplies, the built-in diagnostic functions help to quickly identify the problem.

.NET programming, e.g., by LabView, Python, Matlab

Interface via the optional HMI or RCU

The I/O interface features analog and digital signals used for set and actual values or operating states. Integrated into the user’s control system it is possible to set dynamically changing limits, to use enable signals, or trigger in or outputs. The possibility to activate up to 4 user defined parameter sets using digital inputs means that the system can be adapted to different EUTs. For example, predefined digital fuses and voltage limits can be set.

The wide band AC input accepts all common AC grid systems and has an active power factor correction.

  • AC Grid 380…480 VAC ±10% at 50/60 Hz
  • PF 0.99
  • Efficiency 94…95%, depending on model
