Intelligent Telecom Power Supply System with Real-time Monitoring High Efficiency and Modularized Power Supply Unit
The Intelligent Telecom Power Supply System is a product developed by Entropy Technology for the power and telecommunications industries, ensuring uninterrupted power supply to communication equipment through real-time monitoring. Comprising an AC distribution unit, rectifier module, DC distribution unit, centralized monitoring unit, voltage reduction unit, and battery bank, this system features high efficiency, reliability, stability, easy monitoring, and automated management, making it the ideal power solution for program-controlled switches, power line carrier systems, optical fiber communication equipment, microwave devices, and other communication devices.
A high-efficiency, high-performance, and highly reliable communication power supply specifically designed for various communication electronic devices. It provides stable and reliable -48V DC power primarily for electronic program-controlled switches, microwave equipment, optical fiber communication systems, and similar applications. Widely used in communication rooms across industries, substations of all voltage levels, power plants, and user terminals.
- Busbar voltage loss compensation: In the event of a DC busbar voltage failure, adaptive zero-delay switching can be activated online, effectively ensuring continuous power supply to the DC busbar and enhancing the self-healing capability of the DC power system.
- Battery health monitoring: Proactively prevents DC bus power failure caused by internal open circuits in the battery; actively addresses DC bus voltage loss faults resulting from inherent battery defects.
- Automatic capacity verification via the button: Automates battery capacity verification locally or remotely, reducing personnel requirements.
- Intelligent diagnostic decision-making: Comprehensive intelligent detection and diagnosis of power equipment.
- Comprehensive status monitoring: Effectively detects whether the battery has disconnected from the busbar, preventing operations that may cause voltage loss in the DC busbar.
- Modularized power supply unit: The switch unit consists of a feeder circuit breaker, leakage current transformer (CT), signal lights, data acquisition board, and drawer-type structure, enabling replacement without power interruption.
