System functions and features: rectifier module using the soft-switch technology, high efficiency, good electrical properties and electromagnetic compatibility. Using automatic flow N +1 redundancy modular design. The optional flexible, easy expansion. Automatic switching of dual AC input. Power, and power is restored, the system automatically resume operation. Excellent resistance to short-circuit characteristics: output short circuit can be real-time protection, output voltage is almost zero and can be a long time. Once the short lift automatically resume normal work. Comprehensive battery management functions: batteries are float run automatically converted manage their own monitoring unit, also through remote centralized monitoring computer management. Selection of state-of-the-art microcontroller smart monitoring unit or PLC as the core of online detection and alarm system parameters. Chinese human-machine interface, easy operation. The standard serial communication port, easy-to-with upper computer networking, telemetry, remote control, remote signaling, remote adjustment ". The system is equipped with the HB32 AC protector effectively absorb protection design for different conditions, to ensure reliable operation of the system, prevent power grid surges and high harmonics. Key Performance Indicators: AC304V ~ 456V input voltage range input grid frequency 50Hz ± 10% power factor> 0.938 efficiency> 93% of the output voltage of 185 ~ 305V continuously adjustable output current (110V system 90 to 150V continuously adjustable) 10 to 100% continuous adjustable ripple factor ≤ 0.1% regulation accuracy ≤ ± 0.5% of the steady flow accuracy ≤ ± 0.5% of the current characteristics of the charging current is not balanced between modules degrees ≤ ± 3%
