2). DC Charging Stations and DC-DC Module Testing

• The ITECH IT8400 has demonstrated its stability in CV load mode, faster current response, and stronger ability to withstand startup shocks during long-term use by customers.
• CV Load Mode: Simulates the battery side of an electric vehicle. After the load reaches the set voltage, it must remain stable, ensuring that voltage fluctuations during testing are within the set limits. This validates the charging station's control accuracy and the timing of its protective actions.
• High-Speed Dynamics: DC charging stations generate high-voltage spikes and arcs during power-up, protective actions, or fault tripping. The electronic load must use high-voltage resistant components and optimized thermal management to withstand these brief shocks without malfunction or damage.
• High-Voltage Impulse Resistance: During current step changes in the charging station (such as switching to fast charging mode or SOC changes) or load transients, the load can adjust current within microseconds, accurately replicating the charging and discharging dynamics under real-world conditions.

3). UPS, Energy Storage Systems, and More
