Telecom Power Supply System
This communication power supply system features an N+1 redundant, modular architecture, specifically engineered for modern communication networks and power grid automation facilities. The system's rectifier modules support seamless hot-swapping and plug-and-play functionality, boasting an ultra-wide input voltage range of 85 Vac to 300 Vac. The unit integrates intelligent battery management and secondary load shedding capabilities, while supporting multiple communication interfaces to enable remote, networked monitoring. The product's overall design complies with global certification standards—including CE, UL, and NEBS—making it ideally suited for high-reliability, unattended indoor and outdoor communication power supply environments.
Description
Product Technical Advantages
1. Hot-Swappable N+1 Redundancy: The rectifier modules feature a fully modular design with N+1 fault-tolerant hot backup redundancy. They support non-disruptive hot-swapping under live power, allowing for module replacement without system downtime and ensuring the continuous, stable operation of the load.
2. Ultra-Wide Input Range and High Temperature Tolerance: Boasting an ultra-wide AC input operating range (85 Vac to 300 Vac) and a broad operating temperature range (-40°C to 70°C), the system demonstrates exceptional adaptability to harsh power grid conditions and extreme climatic environments.
3. Intelligent Monitoring and Unattended Operation: The system is equipped with an LCD display and keypad interface, integrating multiple standard communication ports. It supports audible and visual fault alarms, data logging, and remote networking capabilities, making it fully compatible with digital management systems.
4. High-Density Resonant Topology: The rectifier units utilize advanced resonant topology technology; this not only elevates the module’s conversion efficiency to an industry-leading level but also significantly reduces the overall physical footprint of the complete system.
5. Comprehensive Battery Protection: Features built-in, robust safeguards including load disconnection, battery low-voltage protection, and secondary load shedding control. These functions work in conjunction with automatic equalization/float charging and full online battery testing to maximize battery lifespan.
