S03 integrated DC power supply small system is suitable for small switch station, small user substation, system adopts integrated design idea, consists of rectifier module, monitoring module, step-down unit, power distribution unit and battery installation box; it has small size and simple structure. Independently constitutes a system and other characteristics.
The S03 integrated DC power supply small system is easy to operate and easy to install and maintain. The AC input and output cables and DC output cables enter and exit from the bottom of the cabinet. The AC input and output cables and DC output cables are installed on the front of the cabinet. The main features are as follows:
● The rectifier module uses active power factor compensation technology with a power factor of 0.99.
● The AC input voltage has a normal working range of 90 to 300V. The rectifier module uses a comprehensive soft switching technology with an efficiency of up to 92%.
● Perfect battery management. The smart battery has functions such as floating charge management, battery charge current limit, and single battery over/under voltage alarm.
● The rectifier module adopts hot-swap technology, plug and play, and the replacement time is less than 1 min.
● Network design, providing a variety of communication interfaces (such as: RS485, dry contact), flexible networking, local and remote monitoring, unattended, CDT, MODBUS two communication protocol options, 黙 MODBUS protocol.
● Through the LCD screen, the man-machine interface visualization operation, full Chinese menu, easy to operate, easy to use.
● Complete alarm processing and recording function to query system fault records through current faults and historical faults.
● According to the different requirements of the system, the battery inspection and insulation detection and switching unit can be extended through the internal communication port RS485 bus.
● The system uses full isolation technology and the system is highly secure.
● Perfect lightning and DC side lightning protection design, suitable for multiple thunderstorm areas.
● Complete fault protection and fault alarm functions.
● Full front operation and maintenance, which can be installed against the wall, saving space.
● Safe and reliable. The system design is fully compliant with safety standards EN60950 and GB4943.
