Introduction
Behind stable 5G signals, video calls and wireless coverage is the telecom rectifier module — the core of communication power systems.
Main function: Convert grid AC power into standard -48V DC for telecom equipment, and charge backup batteries at the same time
Backup guarantee: Batteries immediately supply power once the grid fails to keep base stations online
Industry background: 5G expansion and edge computing bring higher power consumption, energy-saving and environmental adaptability requirements
Brand highlight: Tonhe rectifier modules adopt mature LLC soft-switching digital power technology, widely used by global telecom operators and integrators
Core Advantages of Tonhe Telecom Rectifier Modules
• Ultra-high efficiency & low energy loss
Peak efficiency up to 98.5%. Reduce electricity cost and heat output, ease cabinet heat dissipation pressure.
• Wide AC input voltage range
85–300VAC input, suitable for unstable power grids in remote, mountainous and emerging market areas.
• High power density, compact and lightweight
Save cabinet space, cut logistics and on-site installation costs.
• N+1 redundant parallel & stable current sharing
One module fault will not interrupt power supply; excellent system reliability for uninterrupted communication.
• Full-range safety protection
Over-voltage, under-voltage, over-current, short-circuit and over-temperature protection to protect modules and loads.
• Intelligent remote monitoring
Support RS485 / CAN interface. Check running data, alarms and adjust parameters remotely, reduce on-site O&M work.
• Adaptive cooling fan
Fan speed adjusts with internal temperature, lower noise and longer service life.
Main Application Scenarios
• 5G macro base stations & 5G small cells: Urban, suburban and rural wireless coverage sites
Outdoor integrated communication cabinets: Adapt to complex outdoor conditions with big temperature difference, dust and humidity
• Central telecom rooms & edge data centers: Parallel operation to build large DC power systems for transmission, optical and switching devices
Power grid communication networks
• Hybrid power stations: Match solar panels + diesel generators for off-grid power supply
• Transportation communication: Railway and highway communication infrastructure
Communication networks keep upgrading, and power supply standards become stricter. Tonhe continuously optimizes rectifier products to meet demands for high reliability, low energy consumption and intelligent O&M. As the fundamental power unit of base stations, high-quality rectifier modules support stable global wireless connectivity. For operators and integrators, reliable rectifier solutions help reduce downtime and control long-term operating costs.
