STS module is mainly used for fast switching between the inverter output and the AC bypass power to comprehensively improve the security and reliability of supply. It receives two sets of AC input and select a group of output. When working online, the STS connects inverter output of power module to the system output. If the power module in a particular time can not provide enough voltage, STS will immediately switch to bypass the power supply.
Adopted foreign advanced high-power thyristors, STS can achieve zero switching, at the same time it has a very strong impact of resistance and ability to withstand short circuit, so that the reliability of the system, and greatly enhanced its stability. It has the following functions such as internal self-testing function; interlock function; the abnormal system output protection function; momentary power failure protection function; output overload and short circuit protection. With RS485 interface, integrated MODBUS communication protocol, standard input and output dry point card. The entire static switch bypass supports online hot-swappable line replacement which does not affect the power supply to the load. It also has UART communication function, which can communicate with system monitor and modular units, sending and receiving orders and all kinds of alarm information at any time.
System monitoring is in the above of cabinet, users can check the working status of the system, the query parameters and event information through display and the operator panel. After the system is installed, all operating system can be completed on the operation panel of the monitor.
The acquisition of system data is completed by a 32 bit digital processor. Display is 5.7 Inch with touch LCD, which enable touch and press operation to meet the different operating habits, which is easy and flexible. It also provides RS232, RS485 communication interface and standard multiple input and output dry point card. With optional TCP / IP cards and GSM SMS, alarm remote network monitoring can be achieved. The system monitor is divided into three regions: the status indicator area, the data display area, the key operating area. Status indicator area provide a simple system status information through the different states of the LED to the user; LCD data display area provides users with detailed system status information through the LCD display, system monitoring display four operator interfaces: SYSTEM, EVENTS,UPSMODULE and SETUP. The system provides a multilingual display, such as the Sino-British, which is a friendly user interface; all operations have achieved a graphical interface, which are simple and straightforward. When users operate the buttons, the LCD screen has a corresponding information display, allowing users to have excellent operating experiences. It makes the operation condition of the system more clearly and management of battery more easily.
