What this product is
What this product is
Functioning as the system's central nervous system, this unit monitors AC mains, DC bus, battery string parameters, and environmental sensors, transmitting telemetry upstream to central OSS/NMS platforms.
What problem it solves
Solves lack of coordination across parallel rectifiers, prevents battery degradation from improper charging regimes, and eliminates delayed alarm notifications during power failures.
Who and where it is for
Engineered for ZTE ZXDU58-series 50A to 300A telecom DC power plants, base station power monitoring, and shelter upgrades.
Core advantages
- Intuitive Multi-Language LCD Screen: Clear bilingual graphical display allows technicians to audit real-time telemetry and modify setpoints with ease.
- Advanced Battery Health Management: Temperature-compensated charging, automated equalize cycling, and dual low-voltage disconnects (LLVD/BLVD) maximize battery life.
- Comprehensive Northbound Interfaces: Provides RS232, RS485, Ethernet, and relay dry contacts supporting standard telecom SNMP network integration.
- Non-Volatile Historical Event Logging: High-capacity onboard memory records detailed timestamped alarm logs that persist through full power outages.
