ABAT100-HS Collector Module Introduction
The ABAT100-HS collector module is used as a management module for a group of battery packs to read the battery monitoring data from the front-end single battery monitoring sub-module and analyze and process the data, which can estimate the remaining capacity of each battery and the whole group of batteries. The operation parameters can be set directly by matching with the touch screen, and the collected data can be viewed directly. The collector module will automatically save the key battery data periodically and can be sent to the third party monitoring system through RS485 port, supporting MODBUS protocol. One collector module manages one group of batteries, and the maximum number of manageable modules is 120.
