The TONHE TH110D20NZ-220AC is a high-performance, natural convection-cooled power module designed specifically for 110VDC electrical applications. Delivering a continuous output of 20A, this module provides the necessary power density to support critical control circuits, protection relays, and breaker operations in substations and power plants.
Unlike traditional forced-air cooled modules, the TH110D20NZ-220AC operates completely silently. The fanless design eliminates common failure points associated with mechanical fans, making it ideal for indoor substations or control rooms where noise reduction is a priority, while preventing intake of corrosive gases or dust.
Safety is paramount in power distribution. This module features advanced "Foldback" short-circuit protection that automatically limits current to below 15% of rated output during faults, minimizing heat generation. The module automatically recovers once the fault is cleared, ensuring maximum system uptime.
Utilizing resonant voltage-mode control technology, this module achieves high efficiency and low ripple. It maintains precise output voltage within a wide range (95V-150VDC), allowing customization for specific battery configurations and load requirements. With operating efficiency ≥93%, it minimizes energy loss and reduces thermal load.
We are a high-tech enterprise integrating manufacturing, sales, system solutions, and after-sales service. With over 290 successful projects for 220 kV to 500 kV substations and battery systems above 1000 Ah, Tonhe has become a leading DC power system supplier in China, holding over 40% market share and producing 1 million modules annually.
Our 8 advanced production lines, equipped with imported machinery, achieve 80% automation and up to 99% first-pass yield. All power modules undergo double-sided potting, conformal coating, and rigorous functional, environmental, and aging tests—ensuring reliable 24/7 performance in critical power infrastructures.
We provide a full range of power conversion modules, system-level low-voltage DC distribution cabinets for DC loads, data center power systems, as well as customized hardware and software power solutions.
