PB-A (Battery Sensor) module

The PB-A battery sensor module is designed specifically for single battery monitoring. PB-A battery sensor advanced technology provides the most comprehensive stationary battery health analysis in the industry.

• Continuous 24/7 online monitoring
• One battery sensor per battery to monitor internal resistance, voltage and temperature
• Software is available to retrieve data from PB-A module
• Serial port with optical isolation, meets Modbus specification
• User-friendly installation

FEATURES

• Full resistance, battery temperature and voltage monitoring for comprehensive battery state of health analysis
• String current and ambient temperature monitoring (requires PB-B module)
• Voltage isolation MODBUS RTU (requires PB-C module)
• All operating parameters can be set via the serial bus
• Signal lights indicate when alarm is raised, which can also be read via the serial bus
• Store historical data
• WEB server is available for management of multiple strings, real-time querying and historical data
