MEAN WELL TN Series True Sine Wave Inverter with UPS
Product Features
The TN series is a high-performance true sine wave DC-AC inverter that integrates a seamless UPS mode, offering dual-function reliability for critical power systems.
- Built-in UPS Function: Automatically transfers to battery power in approximately 10ms during grid failures, ensuring zero downtime for critical loads.
- True Sine Wave Output: Low harmonic distortion (THD < 3%) makes it safe for sensitive electronic loads.
- Configurable Output: Front-panel DIP switches allow users to adjust AC output voltage and frequency.
- Energy Saving Mode: Features an intelligent energy-saving function to conserve battery power when the output load is minimal.
- Advanced Protection: Fully protected against short circuit, overload, over-temperature, and low/high DC input voltage.
- Robust Construction: Industrial-grade design suitable for diverse environments.

UPS Operation Mode Explained
The NTU series delivers an efficient power transition architecture:
| Operation State | Power Flow |
|---|---|
| Grid Normal | AC input powers the load via the internal transfer relay, while the internal charger keeps the battery bank maintained. |
| Grid Loss | System detects loss and switches to Inverter mode within 10ms, drawing DC power from batteries to produce clean AC. |
Selection Tip: Choose your model based on the battery bank voltage (12V/24V/48V) and peak surge requirements of your connected loads. Always ensure the battery bank capacity (Ah) matches the discharge current capability of the chosen NTU model.
