ITECH IT8000 Series: Precise Load Simulation for High-Voltage Batteries and High-Current DUTs
Whether high-voltage battery or low-resistance DUT with extremely high discharge current: The electronic load ITECH IT8000 Series operates with up to 2250 V load voltage and reaches an impressive 8000 A DC load current in a system configuration.
Another key advantage: Up to 95% of the absorbed energy is efficiently fed back into the facility grid.
Flexibility and Precision for Dynamic Test Scenarios
The regenerative DC load operates in CC, CV, CP and CR modes as well as in combined operating modes. This allows the series to reproduce static operating points with the same precision as variable load conditions.
With the LIST function and the integrated arbitrary waveform generator, load steps, ramps and complex load profiles can be simulated with full reproducibility.
With dynamics of up to 500 Hz, the DC sinks support demanding test scenarios with rapid current changes, transient states and high-frequency load cycles.
For advanced battery measurement and testing tasks, you will find the right device in the Battery Measurement Technology category.
Automated Battery Tests and Maximum Operational Safety
For precise discharge tests, the devices automatically stop the test run when defined limits for voltage, capacity or time are reached.
The integrated Power Accumulation function records the exact amount of regenerated energy and makes the economic efficiency benefit of longer test cycles directly transparent.
Standard interfaces enable seamless control via common test software and easy integration into automated test sequences.
Comprehensive protection functions ensure safe operation, even at the highest power levels and with grid-connected regenerative feedback. The devices of the ITECH IT8000 Series monitor grid status, DC input voltage and frequency. In the event of a grid failure, the devices shut down and support grid-connected operation with anti-islanding protection.
Protection functions such as OCP, OVP, OTP and OPP provide additional operational safety.
