- Venue: Dubai World Trade Centre (DWTC), Dubai, UAE
- Edition: The 50th edition, coinciding with the 50th anniversary of the show
- Organizer: Informa Markets, held under the patronage of the UAE Ministry of Energy and Infrastructure, with the full support of the Government of Dubai
- Scale: Over 1,500 global energy companies confirmed to exhibit, covering the full value chain across power, new energy, energy storage, lighting, and water — one of the world's core platforms for energy business and exchange

This edition focuses on smart grids, data center power, renewable energy, and EV charging. Shijiazhuang Tonhe Electronics Technologies Co., Ltd. (Tonhe Technology) is making a strong debut at the show with its 48V Telecom Power Module series at Booth D1-8211, warmly inviting global customers and partners to visit and connect.

Product Introduction
At this exhibition, Tonhe is debuting its TH48 Series 48V Telecom Power Module — a new-generation high-frequency switching rectifier module purpose-built for communication systems. It delivers stable, reliable −48V DC power to telecom base stations, switching centers, access networks, data centers, and a wide range of communication equipment.

The module employs the world-leading "resonant voltage-mode dual-loop controlled power conversion technology" with full digital control. It is available in both naturally cooled (self-cooled) and fan-cooled versions, with output ratings covering 48V/30A, 50A, 75A, and more, and single-module power from 1,440W up to the 12kW class. Multiple modules can be paralleled to build a 48V/600A embedded rectifier power system (e.g., 8×75A configuration) supporting dual 220V AC/DC inputs, with system efficiency up to 96% or higher.

The module is equipped with a standard RS-485 communication interface, with SNMP/network port expansion and battery management support. It provides "four-remote" capabilities (remote measurement, remote signaling, remote control, and remote adjustment), enabling seamless integration with a wide range of automation and environment monitoring systems.

Product Advantages
1. High Efficiency, Low Energy Consumption: System efficiency up to ≥96%, significantly reducing long-term electricity costs and carbon emissions of communication sites — supporting green communication networks.
2. High Reliability, Hot-Swap Maintenance: Full digital control with wide input voltage range; supports N+1 redundancy, autonomous current sharing, and online hot-swapping, allowing failed modules to be replaced without power interruption.
3. High Power Density, Compact Size: Small footprint and light weight greatly save equipment room and site space, reducing construction and upgrade costs.
4. Intelligent Network Management, Easy Maintenance: Standard RS-485/SNMP/LAN interfaces with "four-remote" functions enable remote centralized monitoring — power status can be tracked in real time even in unattended sites.
5. Full Platform, Flexible Configuration: Covers the full voltage range of 48V/110V/220V and the full power range of 0.8kW–12kW, with self-cooled/fan-cooled options, flexibly adapting to site requirements of different scales and environments.

FAQ
Q1: Can this 48V telecom power module be integrated into our existing network management/monitoring system?
Yes. The module comes with a standard RS-485 communication interface and supports SNMP/network port expansion, with "four-remote" capabilities (remote measurement, remote signaling, remote control, and remote adjustment). It can be seamlessly integrated with mainstream environment monitoring and automation systems for remote centralized monitoring and unattended operation.

Q2: What are the cooling options? Can the module operate in harsh environments?
The product is available in two cooling forms: naturally cooled (self-cooled) modules are fanless and maintenance-free, ideal for dusty indoor environments or where noise is a concern; fan-cooled modules offer superior heat dissipation and support online hot-swapping. The modules support a wide input voltage range and stable operation across a wide temperature range, making them suitable for harsh environments such as the high temperatures found in the Middle East.

Q3: How is redundancy backup and future capacity expansion handled?
The modules support N+1 redundancy paralleling with autonomous current sharing — if any module fails, the system automatically rebalances the load to ensure uninterrupted power. For capacity expansion, new modules can simply be plugged in online without power interruption. With single-module power from 1,440W up to the 12kW class, systems can be flexibly built up to 48V/600A or larger, scaling smoothly as business grows.
