A reliable 48V telecom DC power supply is the core backbone of all telecom network infrastructure. As the standard power solution for global telecom sites, the telecom rectifier system converts commercial AC power into stable -48V DC power, continuously powering 2G/3G/4G/5G base stations, communication cabinets, data access nodes and remote telecom equipment. For telecom operators and engineering contractors worldwide, a high-performance 48V rectifier system directly determines network stability, uptime rate and operation cost control.
A telecom rectifier system is an integrated AC-to-DC power conversion and distribution system customized for telecom scenarios. The standard -48V DC output has become the universal industry standard after decades of technical iteration, different from ordinary industrial power supplies.
The complete system consists of three core layers to ensure systematic and stable power supply:
- Power Input Layer: Supports wide-range AC input (90V–290V single-phase / 323V–480V three-phase), adapting to unstable grid power in remote telecom sites and outdoor base stations.
- Power Conversion Layer: High-efficiency rectifier modules complete AC-DC conversion, with active power factor correction (PF＞0.99) to reduce power loss.
- Power Distribution & Backup Layer: Matches 48V battery banks, intelligent monitoring units and protected power distribution terminals to realize uninterrupted power supply.
All mainstream global telecom operators adopt 48V telecom DC power supply systems, mainly due to its unique safety, compatibility and durability advantages, fully adapting to long-term outdoor and unattended telecom site operation:
- High Safety: 48V DC is below the 60V safe voltage threshold, effectively avoiding electric shock risks for maintenance personnel and reducing line failure hazards.
- Strong Compatibility: Perfectly matches 12V lead-acid battery packs (4 batteries in series), the most mainstream backup energy storage solution for telecom sites.
- Anti-corrosion & Stable: Negative ground design reduces corrosion of buried copper communication cables, extending the service life of on-site wiring and equipment.
- Low Operation Cost: High conversion efficiency (up to 96%) reduces long-term power consumption, suitable for large-scale deployment of urban and remote base stations.
