Product Highlights
  • 20A High-Current Output: Engineered for 110VDC systems with robust 20A (2.2KW) output capacity, ideal for medium to large substations and industrial control panels.
  • Fanless & Maintenance-Free: Natural cooling design eliminates noise, prevents dust accumulation, and ensures maintenance-free operation in harsh environments.
  • Ultra-Reliable Protection: Comprehensive protection suite includes short-circuit (foldback), over-temperature, input abnormalities, and output over-voltage protection.
  • Industrial Durability: Built to operate in extreme temperatures (-10℃ to +40℃) with high efficiency for long-term reliability in critical infrastructure.
  • Hot-Swappable Design: Modular structure supports N+1 redundancy and hot-swapping for easy maintenance without system shutdown.
Product Description
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.
Silent Operation for Sensitive Environments
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.
Engineered for Safety and Stability
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.
Precision Power Conversion
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.
