With the rapid upgrading of modern industrial intelligence, automation, and digitalization, industrial control systems and precision manufacturing equipment impose strict requirements on power supply stability, efficiency, and continuous operation. Conventional power supplies are vulnerable to grid fluctuation, extreme temperature, and strong electromagnetic interference, easily causing output deviation and equipment downtime. As a leading power electronics solution provider, Tonhe Technology has decades of in-depth experience in industrial DC power supply research, design, and engineering implementation. The company launches a full-series industrial DC power supply solutions featured with high reliability, full digitalization and intelligent O&M, which are widely adopted in smart grid, metallurgy, chemical industry, rail transit and intelligent manufacturing fields, providing stable and safe DC power guarantee for industrial digital upgrading.
Tonhe’s industrial DC power solutions rely on self-developed high-frequency soft-switching power conversion core technology, breaking the limitations of traditional analog power supplies such as high energy consumption, large ripple and poor stability. As one of the earliest domestic enterprises mastering full soft-switching technology, Tonhe applies full-digital control architecture to its core 6U series power modules. The optimized circuit design achieves ultra-low ripple, high precision voltage and current stabilization, and wide voltage adaptation. This core technology effectively resists complex grid fluctuations in industrial sites, ensuring long-term consistent and accurate DC power output for precision industrial control equipment and sensor systems.
Tonhe has built a comprehensive industrial DC power product layout covering full voltage and power segments. The product lineup includes mainstream industrial voltage grades of 48V, 110V and 220V, with power ranges from 0.8kW to 12kW. Both self-cooling and air-cooling heat dissipation configurations are available to match light-load and heavy-load industrial scenarios flexibly. Supporting the hardware system, the self-developed THJK070G intelligent monitoring system is equipped with a 7-inch touch human-computer interaction screen. It realizes real-time module data collection, battery status monitoring, fault automatic alarm and remote data transmission. Meanwhile, built-in IRIG-B time synchronization interface and multi-channel fault output interface support seamless docking with industrial automation platforms, realizing full-scene intelligent management of DC power systems and greatly reducing manual maintenance pressure.
High environmental adaptability and intrinsic safety are the core competitiveness of Tonhe’s industrial DC power solutions. All products pass strict industrial-grade reliability tests, possessing excellent performance of high and low temperature resistance, anti-vibration, dust-proof, moisture-proof and strong electromagnetic interference resistance. The system supports flexible capacity configuration from 10Ah to 3000Ah, covering power demands from small industrial control terminals to large complete industrial equipment. In terms of safety protection, the solution integrates perfect over-voltage, over-current, over-temperature and short-circuit self-protection mechanisms. Once grid abnormality or equipment failure occurs, the system can quickly trigger protection and isolate faults to avoid equipment damage and production safety accidents, ensuring uninterrupted operation of industrial production lines.
The solution reserves standard RS485 communication interfaces, which are highly compatible with mainstream industrial Internet and automatic monitoring platforms. It supports remote real-time data monitoring, operational data statistics and fault early warning, realizing unattended intelligent operation and maintenance of power supply equipment. Adopting modular assembly design, the system supports rapid installation, disassembly and capacity expansion. Enterprises can flexibly upgrade and expand the power system according to production line iteration and capacity expansion plans, effectively reducing later reconstruction, operation and maintenance costs and improving the overall service life of power equipment.
Tonhe’s industrial DC power solutions have been fully verified by massive industrial projects, forming mature landing experience in multiple core fields:
