Regatron G5.SRC Programmable DC Power Supply Series

G5.SRC Programmable DC Power Supply Series

The G5.SRC series are unidirectional sources that can operate in CV, CC, or CP 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.SRC series is characterised 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.SRC power supplies to be optimally adapted to special customer application requirements.

The output of an individual power supply is in the range from 0.9 kW to 2000+ kW, up to 3000 VDC. The advantageous modularity of REGATRON power supply solutions allows the system to be easily adapted to everchanging 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 multi-unit systems, REGATRON also offers turnkey 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. Applications and Features The high accuracy and dynamics of the G5.SRC series, as well as the ability to easily change between different multi-unit configurations, make this series the ideal power supply solution for unidirectional R+D tasks and test bench applications such as testing of inverters or simulation of DC sources like e.g., fuel cell stacks. 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 preprogrammed over-voltage 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.SRC series also offers the possibility to store, edit, and recall any device configuration on board the power supply.

G5.SRC 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 P-HIL 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 fast
analog port. Time analog-in to power output is typically
90 μs.

Accuracy
The G5.SRC series has an exceptional voltage accuracy
of 0.01…0.02% FS. The current accuracy is in the range
of 0.03…0.09% FS depending on the model. There is
even an additional high-resolution current measurement range from 0 to 10% FS with an accuracy of better
than 0.005% FS.
