G5.DT Drivetrain Inverter Test Solution
The G5.DT series is bidirectional regenerative. It was developed specifically for testing DC components of the electrical drive train or of other parts of the vehicle’s electrical system. It is suitable for use in laboratories and on test benches. The modular and finely graded G5.DT series is characterized by highly dynamic response times, adjustable filter time constants,
and a wide current-voltage range with an auto-ranging factor 3. The power supplies are equipped with a powerful CAN multi-protocol interface (1 kHz, 16 bit) and optionally offer test bench relevant safety functions such as PL e according to EN ISO 13849, insulation monitoring as well as automatic discharge on the load side in case of a shutdown.

Drivetrain-Component Testing Features
The G5.DT series for testing electrical components of the drivetrain has a high functional range and extraordinary dynamics with an optimized output filter stage for this application. Furthermore, extensive safety options are available.
- Emergency stop circuit with PL e according to EN ISO 13849
- Integration of insulation monitoring device into the safety circuit and the CANmp interface
- Discharge of residual energy from rotating loads by the additional DC discharge unit (DDU) after shutdown of the test bench
- Simplified and safe operation thanks to pre-programmed overvoltage protection and digital fuses with immediate and I2t triggering. Different protection levels for different DUTs are 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
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. The G5.DT series also offers the possibility to store, edit, and recall any device configuration on board the power supply. Thanks to these properties, REGATRON drivetrain testers are used worldwide in test benches of all well-known automobile manufacturers, suppliers, research and testing institutes.
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.

G5.Control over Ethernet or USB
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.
API .NET over Ethernet or USB
.NET programming, e.g., by LabView, Python, Matlab
WebAPI (REST) over Ethernet or USB
Interface via the optional HMI or RCU
CAN Interface
The CAN multi-protocol (CANmp) interface has a 1 kHz data rate, a 16-bit resolution, and is adaptable to any proprietary CAN bus. In addition, it supports dbc file handling.
Integrated Safety Relay
Integrated safety relay (ISR) for increased emergency stop reliability supporting performance level PL c / PL e according to EN ISO 13849.
I/O Port
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.
Grid Connection
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
