Introduction
The 3KW 48V rectifier module converts alternating current into stable 48V DC power, widely deployed in 5G base stations, telecom central offices, edge data centers, battery charging systems and industrial DC power cabinets. As a 1U rack-mount hot-swap power unit, it delivers steady 3000W output to guarantee 24/7 continuous operation of critical power loads. If you are sourcing high-performance telecom-grade rectifier modules for overseas projects, this 3kW 48V power rectifier is your ideal option.
Core Product Advantages
1.High Conversion Efficiency & Energy Saving
Peak efficiency up to 96%, high power factor 0.99. Low heat generation reduces cooling power consumption and cuts long-term operational electricity cost for your sites. Less heat also extends the service life of batteries and other cabinet components.
2.Wide AC Input Voltage Adaptability
Supports 85~300VAC wide input range, works stably under unstable grid voltage. Perfect for remote rural base stations, areas with fluctuating power grids in Southeast Asia, Middle East and Latin America.
3.Full Protection Mechanism & High Reliability
Built-in over-voltage, under-voltage, over-current, short-circuit, over-temperature protection. Automatically shut down or recover to avoid equipment damage. Designed for 24/7 continuous operation, MTBF reaches over 500,000 hours.
4.Hot Swap & N+1 Redundancy Parallel Design
Hot-pluggable module, replace single unit without powering off the whole system. Multiple modules support parallel current sharing, N+1 redundant configuration to prevent power outage risk when one module fails.
5.Digital Intelligent Monitoring
Digital control design, supports CAN/RS485 communication. Real-time remote monitoring of output voltage, current, temperature and fault alarm via monitoring host. Easy for centralized operation & maintenance.

Successful Export Case
We supplied bulk 3KW 48V rectifier modules for a telecom operator project in Southeast Asia. The customer needed to upgrade outdoor 5G base station power cabinets, facing unstable local grid and high ambient temperature.
We delivered hundreds of 3kW 48V rectifier modules with full test reports and Form E certificate. After on-site installation, the modules ran stably under wide voltage fluctuation and high temperature environment. N+1 redundant configuration ensured no power interruption.
The customer finished the network upgrade smoothly. Up to now, the failure rate is extremely low. This project becomes our repeat cooperation case, and the customer continues to place quarterly replenishment orders.
FAQ
Q1: What is the output voltage range of this 3KW 48V rectifier module?
