G5.IND Inverter and Charger Test Power Supply

The G5.IND is designed as an economical choice for bidirectional  regenerative DC applications and is optimized for inverter and charger test environments. This includes manufacturing, automotive, green energy, and electronics. It operates in CV, CC, CP, or CR control modes with simulation of internal resistance in CV mode or internal conductance in CC mode. The modular and finely graded G5.IND series has a wide current-voltage range with an auto-ranging factor of three.

It provides a variety of power levels for single-channel operation and parallel operation with different power classes. The device series offers a wide range of optional communication interfaces for use in automated R+D test benches or for end-of-line test purposes. The integrated safety feature ISR ensures reliable power cut-off and enables simple integration into the higher-level emergency stop circuit without additional complex installations.

Applications and Features

The functional scope of the G5.IND series is ideal for basic performance tests of power conversion systems (PCS), tests of inverters for energy storage systems (ESS), or for testing chargers in high-volume end-of-line testing.

The operating and maintenance software G5.Control allows complete control of the power supply unit or entire multi-device system and offers a range of service functions.

Features such as adjustable controller settings and the integrated powerful 8-channel digital scope assist the user to quickly and easily achieve optimal system behavior for a special application requirement. Different application-specific settings of parameters for single devices or master-slave systems can be saved on the devices and recalled by G5.Control, an API, or any optional communication interface.

Simplified and safe operation can be provided by programmable overvoltage protection and digital fuses with immediate and I2t triggering. Different protection levels for different DUTs can be programmed by G5.Control software or the user’s automation test system via various interfaces.

Firmware updates can be carried out quickly and easily for individual units or master-slave systems with a single command. A built-in diagnostic is available when handling support cases concerning the application of the power supplies.

Modular and Easily Scalable Systems

The output of an individual power supply ranges from 0…18 kW to 0…1000 kW, up to 1500 VDC. The advantageous modularity of REGATRON power supply solutions allows the system to be easily adapted to ever-changing test requirements. The system can be expanded with additional power supply units or split into smaller units right down to single-use with multiple channels.
Whether for single devices or powerful multi-device systems, REGATRON also offers turnkey cabinet solutions or project-specific system integration according to customer specifications.
Therefore, purchasing a REGATRON power supply is a solid investment for the future.

Modular concept for easy power increase by parallel operation, which allows even the operation of devices with different output power, e.g., 18, 36, and 54 kW modules, in one system

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. 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.
