GrandPower U400-S UPS battery monitoring system

The 1.8m-2.2m cabinet is configured separately for the battery monitoring system, and the monitoring system is placed in the cabinet. This method is suitable for the centralized installation of multiple modules and batteries. The cabinet installed separately can keep the whole consistency of the distribution room and facilitate centralized management of the battery monitoring management system. However, this method may cause the sampling line of some batteries to be connected longer, and the construction difficulty is relatively larger than other methods.

For the use of space is limited, requiring battery monitoring system accounted for smaller, do not have the cabinet or rack for the battery monitoring system to provide installation space for the use of the site, wall-mounted installation is the most space-saving installation. When using this installation method, please specify the wall mount installation of the battery monitoring system when ordering.

When the battery rack / battery cabinet is designed, the installation position is reserved for the battery monitoring management system. Configure small cabinet or related installation equipment for U400 battery monitoring management system. This method can ensure the battery monitoring system and battery group organically combined, the battery monitoring system and each battery group between the sampling line can be the shortest. However, when using this installation method, we should make a comprehensive planning for the system in the system design, especially for the storage and installation of the battery monitoring system to do the corresponding planning.

U400-S battery data acquisition module connected with each battery, real-time online collection of single battery voltage, group current, ambient temperature and other operating parameters. U400-S module can be used alone to achieve single-cell battery voltage, group current, ambient temperature and other operating parameters of real-time monitoring to achieve the single battery resistance measurement and real-time monitoring.

U400-DAU data acquisition module is divided into U400-S-12V and U400-S-2V two models, respectively, for the 12V battery battery system and 2V battery battery system consisting of detection and data collection. Multiple U400-DAU can be connected through the 485 interface to achieve the different battery configuration for the UPS system data collection.

U400-TP touch screen module can be data display, system settings, operation and control for U400 system. 5.7 "touch screen display data at a glance, the operation is quick and easy. Sound and light alarm, the first time to indicate the battery system alarm information. Its control and operation functions, to facilitate the U400 system system information set and calibration.

【Data query】on the battery voltage, current, ambient temperature, single cell voltage and internal resistance and other data display. 

【Internal resistance test】 through the manual way to start the battery resistance test. Keep abreast of the internal resistance of each battery. 

【Alarm Query】 Displays the real-time alarm status and related alarm information.

【System Settings】 The system parameters are calibrated and set.

The main control unit is connected with the U400-S2 module through the RS485 interface to collect the monitoring data of each module in real time and carry out data processing and alarm judgment. The main control unit controls the touch screen operation simultaneously and controls and responds to various field operations of the touch screen.

Through the main control unit built-in RS485 interface, can be achieved based on modbus and other means of the host computer centralized monitoring communications.

UPS battery configuration: The 4 groups of batteries are connected in parallel, with 12V*35 cell in each group;

Battery monitoring system includes: U400-S2-C32 model * 4; U400-TP (optional) * 1; through the RS485 bus to achieve the host computer monitoring.

UPS battery configuration: The 4 groups of batteries are connected in parallel, with 12V*24 cell in each group;

Battery monitoring system includes: U400-S2-C48 model *2 ; U400-TP (optional) *1;

Through the Ethernet bus to achieve the host computer monitoring.

At this point, each U400-S2 module can simultaneously monitor two groups of batteries used in parallel.
