| ||
Output maximum current | Three phase: 56±2A, single phase: 20±2A |
| ||
Voltage ripple factor | ≤±1% |
| ||
Current accuracy | ±3% | Half load or more | ||
Efficiency | ≥94% | Rated voltage Full load | ||
Parallel function | Networking is performed by internal CAN communication, and up to 8 modules can be connected in parallel. |
| ||
Output response time | The rise time of the output voltage of the car charger should be less than 300ms, and the overshoot should be less than 10%. After receiving the shutdown command, the current drops below 10% within 300ms and drops to 0A within 500ms. |
| ||
Other protection features | Input overvoltage, input undervoltage, output overvoltage, output undervoltage, short circuit, output overcurrent, overtemperature, reverse connection protection, potential equalization and ground protection, power failure protection. |
| ||
Over temperature protection | When the temperature reaches 85 °C, the output power is reduced by half. The temperature is <80 °C in 10 minutes, and the full load is automatically restored. After 10 minutes, the temperature is >80 °C, then it is turned off. When the temperature is >90 °C, it will be shut down directly. |
