Customizable system capacity and cabinet configuration.

The following specifications are typical configuration options. Actual parameters can be customized according to project requirements.

1. Stable -48V DC Power Output

Designed for telecom equipment requiring a standard -48V DC power supply. The system provides regulated DC output to support continuous operation of base stations, transmission equipment, and communication devices.

2. High-Efficiency Modular Rectifier Design

Multiple rectifier modules work together to convert AC power into DC power. The modular structure allows flexible capacity configuration and makes it easier to expand the system when telecom power requirements increase.

3. N+1 Redundancy for Higher Reliability

The system supports N+1 redundant operation. When one rectifier module fails, the remaining modules can continue supplying power within their available capacity, reducing the risk of service interruption.

4. Intelligent Monitoring and Management

The monitoring unit collects operating information such as input voltage, DC output voltage, output current, battery status, and module operating conditions. Optional communication interfaces enable remote monitoring and alarm reporting.

5. Integrated Battery Backup

The system supports battery connection and automatic charging management. When AC input power is interrupted, the battery can supply DC power to connected telecom loads, helping maintain communication services.

6. Flexible DC Power Distribution

The system can be configured with multiple DC output branches and independent circuit breakers. Different output circuits can be assigned to base station equipment, transmission devices, and other DC loads according to project requirements.

7. Easy Installation and Maintenance

The modular design supports convenient installation, replacement, and maintenance. Hot-swappable rectifier modules can be replaced without shutting down the entire system when the system is properly configured and operating within its redundancy capacity.

1. 4G / 5G Telecom Base Stations

Provides continuous -48V DC power for wireless communication equipment, baseband units, radio units, and transmission devices.

2. Outdoor Telecom Power Cabinets

Provides integrated DC power conversion, battery charging, and distribution for outdoor communication cabinets installed in remote or unattended locations.

3. Telecom Shelters and Equipment Rooms

Supplies stable DC power to communication equipment, network transmission devices, and supporting infrastructure.

Q1: What is a 48VDC telecom power supply system?

A: It is a DC power system that converts AC input power into regulated -48V DC power for telecom equipment. It typically includes rectifier modules, a monitoring unit, battery connections, and DC distribution components.

Q2: Why do telecom base stations use -48V DC power?

A: -48V DC is a widely adopted telecom power standard. It provides a consistent power supply for communication equipment and supports battery backup during AC power failures.

Q3: Does the system support N+1 redundancy?

A: Yes. The system can be configured with N+1 redundant rectifier modules. If one module fails, the remaining modules can continue supplying the required load, provided sufficient capacity remains.

Q4: Can the 48VDC telecom power system support battery backup?

A: Yes. The system supports compatible battery banks and automatic charging management. Batteries can supply power to connected loads when the AC input is interrupted.
