Product Description
TONHE TH110D20ZZ-3 2.2KW Intelligent DC Power Module
The Standard for 110V Substation Reliability
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 (2.2KW), 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.

Load Rating

Continuous operation at 100% rated output current (Class I)

Automatic Current Limiting

When output current exceeds the set limit, the module operates in constant current mode and the output current will not increase

Output Overvoltage Protection

The module automatically stops output when voltage exceeds 160±3VDC to prevent equipment damage

Output Short-Circuit Protection

The module self-protects in case of short circuit to prevent damage and automatically recovers after fault removal

Note: Voltage regulation accuracy does not include the effect of the built-in isolation diode.
