DC Power Ecosystem for Modern Data & AI Compute Facilities
Today’s data and artificial intelligence computing environments face challenges from power fluctuations, rising power density, and strict sustainability requirements. Tonhe Technology provides a full-stack DC power management ecosystem built on years of power electronics innovation. Our modular rectifier hardware and coordinated power control systems deliver stable, adaptive, and future-ready DC power for mission-critical infrastructure, supporting variable GPU workloads, hyperscale cloud rollouts, and retrofits of existing facilities.
Core Power Conversion Modules
Our lineup of digitally controlled AC-DC rectifier units covers a broad range of DC bus specifications to accommodate diverse infrastructure designs.
Low-voltage 48V rectifier units: Engineered for telecommunication rooms and edge data sites. These units feature compact dimensions, hot-swap functionality, and precise output voltage regulation.
240V & 336V HVDC modules: Mature, field-validated power blocks for mainstream IDC applications. Adopting high-frequency soft-switching topology and rugged potting encapsulation, they maintain consistent performance across wide temperature ranges and complex electromagnetic interference conditions.
Next-generation 800V SiC-enabled HVDC modules: Purpose-built for high-density AI racks. Silicon carbide switching devices reduce switching losses and deliver exceptional light-load efficiency. Each 30kW unit supports cabinet stacking; a single cabinet can hold up to 24 modules to reach 720kW capacity, with scalability to multi-megawatt clusters for large-scale computing campuses.
Optional liquid-cooled modules: Developed for ultra-high-density AI rack deployments. Optimized heat dissipation lowers overall facility PUE and reduces operating noise, easing thermal management burdens for densely packed GPU clusters.
Solution Architecture & Key Differentiators
Adaptive Modular Scaling & Redundancy
The hot-pluggable module design enables incremental capacity expansion without service outages. N+1 / N+M redundant configurations eliminate single-point failure risks. A separated cabinet layout for AC input, rectifier banks, and DC distribution supports prefabricated assembly, shortening on-site installation and commissioning timelines for both new builds and facility renovation projects.
Optimized Energy Efficiency & Reduced Operational Expense
Dynamic load-aware module sleep logic automatically adjusts active modules based on real-time IT power consumption. This maintains strong efficiency performance across partial and full-load operating ranges. SiC power technology minimizes conversion losses, effectively cutting long-term electricity costs and helping data centers achieve carbon reduction targets.
Intelligent Power Orchestration & Open Interoperability
The embedded supervisory control platform collects real-time telemetry from every power module, tracking voltage, current, temperature, and equipment health status. It supports standard communication protocols for seamless integration with DCIM, BMS, and remote monitoring systems. Operators gain access to remote fault alerts, equipment diagnostics, and predictive maintenance capabilities to simplify centralized power asset management.
Comprehensive Protection & Robust Hardware Design
Every module incorporates multi-layer protection mechanisms, including input over/under voltage protection, output overvoltage protection, short-circuit protection, over-temperature protection, and fan fault protection. The hardware is engineered to operate over a wide temperature range with strong anti-interference performance, complying with global and industry standards for data center HVDC infrastructure.
