Product Introduction
Requirement: Explain the usage scenarios of the product and the approximate functions it achieves
The battery voltage acquisition module is used for measuring the voltage of a single battery in an uninterruptible power supply (UPS) battery, and provides an RS485 bus communication interface to meet the information acquisition requirements of external acquisition systems. The product adopts a common positive voltage difference measurement mode and achieves voltage measurement through A/D conversion and multi-channel time-division acquisition technology. Externally, the MOBBUS RTU standard communication protocol is adopted to meet the information collection requirements of the upper computer and system for multiple blocks and multiple voltages.
