Frequently Asked Questions (FAQ)
Q: What is the input voltage range supported by these modules?
A: The input voltage ranges from 90~280Vac for the 21kW model, and 260~530Vac for the 75kW and 400kW models, allowing them to adapt to a wide variety of power grids.
Q: How efficient are these charging modules?
A: These modules operate with high efficiency across the full load range, achieving a peak efficiency of greater than 95% when fully loaded.
Q: What kind of protection features are built into the system?
A: The system includes input undervoltage protection, output overvoltage protection, over-current and short-circuit protection, over-temperature protection, and battery anti-reverse flooding protection to ensure safe and reliable operation.
Q: Can the modules be hot-swapped during maintenance?
A: Yes, the modules support non-destructive hot-swapping (plug-and-play), which allows for highly convenient maintenance and minimal downtime.
Q: What are the recommended environmental conditions for operation?
A: The operating temperature range is -40ºC to +75ºC (derating applies above +55ºC). They can operate in humidity up to 95%RH (without condensation) and at altitudes up to 2000m without derating.
Q: How is the system status monitored?
A: The modules utilize CAN communication for monitoring, accompanied by LED indicator lights (Green for normal operation, Yellow for protection alarms, and Red for fault alarms).
