The YX-48V-M12-W03 Battery Online Monitoring Host is a professional industrial-grade monitoring device specifically designed for 48V communication power supply systems and DC backup power scenarios. Based on a high-performance Cortex-M4 core processor and μ cos-II operating system, this device serves as the core management unit for battery monitoring networks. It accurately collects real-time parameters such as single-cell voltage, internal resistance, temperature, and group current (via sensors), supporting passive equalization and intelligent diagnosis. With its compact design and rich interface, it is ideal for 48V DC screen monitoring and remote management.

• All-round Precision Monitoring: Accurately collects critical parameters including single-cell voltage, internal resistance, pole temperature, group voltage, charge/discharge current, and ambient temperature. Utilizes imported high-precision chips to ensure data reliability for battery health assessment in 48V systems.
• Intelligent Battery Diagnosis: Built-in expert diagnosis model for battery performance analysis. It accurately predicts the State of Charge (SOC) and judges battery performance, providing targeted maintenance suggestions to prevent failures before they occur.
• Passive Equalization & Activation: Features built-in passive equalization charging function. This helps optimize battery performance, mitigate imbalances between cells, and significantly extend the service life of the battery pack.
• Robust Communication & Networking: Equipped with 3 SBUS ports, 2 RS485 interfaces, and 1 Ethernet port. Supports standard protocols (MODBUS/RTU, MODBUS/TCP) for seamless integration with SCADA systems and third-party platforms, enabling centralized remote management.
• Industrial-grade Reliability: Designed with high EMC and isolation circuits to withstand harsh industrial environments. Features a built-in "watchdog" circuit for automatic recovery under any anomalies, ensuring 24/7 stable operation.
• High Stability Design: Certified by national Open Laboratory, it boasts an MTBF exceeding 100,000 hours and 2000VAC insulation withstand voltage. The fanless design ensures silent operation and maintenance-free reliability in critical infrastructures.
