Technical Highlights
Compact Design – Everything in one 19" rack, mobile and easy to integrate.
High Efficiency – Efficiency rates of up to 99 %.
Wide Frequency Range – Sine frequencies up to 4 kHz, switching frequencies up to 50 kHz.
Powerful – Simulated active power up to 558 kW per 8HE power module.
Intuitive Operation of the Active Cooling Unit – Touchscreen with clear status display
Technical Description
The IRS SiC Roadrunner is a compact Active Motor Load Emulator designed specifically for the requirements of modern inverters. With a maximum DC voltage of 950 V and a DC current of up to 600 A, the system allows the simulation of highly dynamic load profiles under realistic conditions. Thanks to a wide frequency spectrum – sine frequencies up to 4,000 Hz and switching frequencies up to 50 kHz – the Roadrunner is ideally suited for tests in the fields of electromobility, power electronics, and the energy sector.
The simulated active power of the DUT is an impressive 558 kW.
Despite this enormous testing power, the system requires only a connection power of about 16–20 kW and is operated via a CEE three-phase power supply 400 V / 32 A (other variants for US power grids available upon request).
An integrated cooling unit ensures efficient heat dissipation and additionally provides supply and return connections for cooling the DUT.
This allows even extremely powerful tests to be conducted with minimal grid load and without external cooling infrastructure – a crucial advantage for laboratories with limited resources and maximum cost efficiency due to low operating costs and the elimination of additional investments.
The emulator impresses with an efficiency of 98.74 %. Almost all the energy used is utilized for the simulation, while losses remain minimal.
The system is housed in a robust, mobile rack and offers compact plug systems for connecting high-voltage lines as well as standardized interfaces such as CAN and fiber-optic communication (POF) for easy integration into existing testing setups. The cooling circuits are easily accessible through supply and return connections. Operation is via an intuitive touch interface that provides clear visualization of all operating states.
With its compact design, high performance, and flexible configuration options, the IRS SiC Roadrunner is the ideal solution for demanding inverter tests in minimal space – and that at a connection power that is negligible compared to the simulated test power.
