Telecom Power Supply

Integrated Telecom Power Solutions, Hybrid Power, Fully Customizable.

Industry Overview

Telecom Power Supply

An integrated hybrid energy power supply solution that combines multiple energy inputs such as mains power, photovoltaic, diesel generators, and energy storage. It provides stable, efficient, and reliable -48V DC power for base stations, outdoor sites, and other scenarios, while optimizing energy consumption and reducing costs and carbon emissions.

Industry Challenges

Complex Multi-Energy Integration

Requires seamless switching and coordinated scheduling of multiple energy sources including mains, PV, diesel, and energy storage.

Harsh Grid Environment

Needs high tolerance for voltage fluctuations, frequent power outages, and harmonic interference in unstable power grids.

Energy Cost Pressure

High operational electricity and fuel costs drive the need to maximize renewable energy utilization for lower total cost of ownership.

Stringent Deployment Conditions

Must withstand harsh environments (high temperature, humidity, dust) while meeting requirements for compact size and easy deployment.

Difficult O&M Management

Geographically dispersed sites increase manual inspection costs, requiring enhanced remote monitoring, intelligent alarming, and management capabilities.

Our Solution

Telecom Power Supply

High-Efficiency Rectifier Module

Third-generation high-efficiency rectification topology with system efficiency up to 96%+, wide input voltage range (90–290 VAC), hot-swappable, current-sharing parallel operation, and intelligent sleep/wake-up function — designed for complex grid environments worldwide.
Representative products: RM4820 / RM4850 / RM4875 series rectifier modules.

PV Converter Module

Integrated MPPT algorithm with conversion efficiency ≥98%, supporting automatic switching among PV-priority, grid-complementary, and peak-shaving modes. Single-module power covers 3/4 kW, enabling flexible PV capacity expansion.
Representative product: PVM series PV converter module.

Smart System Controller

As the core control unit of the hybrid power system, it enables unified scheduling and coordinated management of rectifier modules, PV converters, battery banks, and diesel generators. It features a local LCD display, dry-contact alarm, RS485/Ethernet communication, and compatibility with standard protocols including Modbus and SNMP – integrable with power and environment monitoring platforms for site-level remote operation and maintenance (O&M).
Representative product: Smart Site Controller.

Value Contained

Significantly Reduce OPEX

PV-first power supply cuts grid and diesel consumption, optimizing full-lifecycle TCO.

Guarantee Power Continuity

Seamless multi-source switching + storage backup ensures zero-downtime operation even during grid outages, achieving 99.99% site availability.

Accelerate Green Transition

Clean energy replaces fossil fuels, reducing carbon emissions by tons per site annually and supporting operators' ESG goals and carbon-neutral commitments.
