Product Highlights
Optimal 20A Performance: Specifically designed for 110V systems with robust 20A output, ideal for medium-capacity substations and power plants.
Ultra-High Efficiency: Achieves industry-leading efficiency of ≥95%, significantly reducing energy consumption and heat generation.
Fanless Natural Cooling: Features completely fanless design, eliminating noise and preventing dust accumulation for maximum reliability in harsh environments.
Intelligent "Four Remote" Functions: Built-in RS485 interface supports Telemetry, Tele signaling, Tele control, and Tele regulation for seamless automation integration.
Military-Grade Protection: Comprehensive protection includes Short-Circuit (Foldback), Over-Temperature (Auto Shutdown), and Output Over-Voltage (160V±3V lockout).
Product Description
The TONHE TH110D20ZZ-3 is a high-density, natural convection-cooled power module engineered specifically for 110VDC electrical systems. With a rated output of 20A (3KW), this module strikes the perfect balance between power density and physical footprint, making it the go-to choice for distribution networks, hydropower stations, and industrial control panels.
Silent & Dust-Proof Operation
Unlike forced-air cooled modules, the TH110D20ZZ-3 utilizes a fanless design. This eliminates the risk of fan failure and prevents dust from being sucked into the electronics—a critical advantage in dusty industrial environments. The module operates silently and relies on advanced thermal management to maintain performance within the -10℃ to +40℃ temperature range.
Precision Power with 95% Efficiency
Powered by advanced resonant voltage-mode dual-loop control technology, this module delivers exceptional performance. It boasts a ≥95% efficiency rating and an ultra-low ≤0.2% ripple coefficient, ensuring clean, stable power for sensitive protection relays and control circuits. The high efficiency also means less heat is generated, extending the lifespan of your entire power system.
Plug-and-Play Intelligence
Equipped with a standard RS-485 interface, this module supports the "Four Remote" functions (Remote Measurement, Remote Signal, Remote Control, Remote Regulation). You can easily monitor voltage, current, and alarms in real-time, or control the module's output remotely via a master controller (e.g., THJK002G-3). The front-panel LED display and intuitive buttons allow for manual voltage adjustment and status checking without needing additional tools.
