Information about the MEAN WELL NTU-1200-248EU

The MEAN WELL NTU-1200-248EU is a high-performance 1200W DC-AC off-grid true sine wave power inverter with a built-in AC bypass UPS function. Operating from a 48V DC battery input, it converts direct current into clean 230V AC power with total harmonic distortion of less than 3%. This "EU" model comes equipped with a standard European Schuko AC receptacle.

Featuring a rapid transfer time of typically 10 ms, the inverter ensures an uninterrupted power supply by automatically switching to inverter mode when the AC grid fails or fluctuates beyond limits. Output voltage (200V–240V AC), output frequency (50Hz/60Hz), and power-saving modes are easily adjustable via user-friendly DIP switches. Offering a top-tier efficiency rating of ~93%, a wide operating temperature range (-25°C to +70°C), RS-232 monitoring capability, and full electrical protection, it is an optimal choice for 48V telecom setups, industrial backup systems, marine setups, and off-grid solar installations.
