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.
