RBS Series Regenerative Bidirectional DC Source
Description

The launch regions currently exclude the United States, Europe, and Japan.

The RBS Series regenerative bidirectional DC Source is a versatile, programmable power solution with both power (source) and load (Sink) capabilities. It is specifically designed for testing power conversion devices and energy storage components in the new energy sector. Widely used in the development and production testing of electric vehicles, energy storage systems, and related products.

The RBS series supports energy recovery, enabling enterprises to “implement ESG from the equipment selection stage” and incorporate energy-saving performance indicators into their ESG reports.

The RBS series regenerative bidirectional DC Source features built-in SAS (EN50530, Sandia), SAS2, and customizable models. It also supports static/dynamic MPPT testing as well as complex solar irradiation simulations, such as cloud shading and cloud movement.

The RBS series is capable of simulating battery characteristics in practical applications, including charging and discharging behaviors, to assist with various tests.

The RBS series has 8 fixed battery models + one custom battery model. (models are based on relevant research papers and test data published domestically and internationally): lithium manganate (LMO), lithium cobalt oxide (LCO), lithium iron phosphate (LFP), ternary lithium (NCM), lithium titanate (LTO), lead-acid (Pb), nickel-metal hydride (NiMH), and nickel-cadmium (NiCd) batteries.

In traditional motor driver testing setups, a conventional DC power supply typically requires an external diode at the output to prevent reverse current flow, and an additional electronic load is needed to consume the regenerative current generated during motor braking or downhill operation. However, the RBS Series can function both as a DC power source and as a DC electronic load. This dual functionality simplifies configuration, saves space, and is ideal for motor driver testing. Moreover, it can feed the regenerative energy back into the grid, enhancing energy efficiency.
