Mean Well NTS/NTU Series User Manual: High Reliable Inverter (EN)

NTS/NTU series are MEAN WELL's new generation high-reliability off- grid DC-AC pure sine wave inver ters. The whole family has N T S - 2 5 0 P / 4 0 0 P, N T S - 3 0 0 / 4 5 0 / 7 5 0 / 1 2 0 0 / 1 7 0 0 / 2 2 0 0 / 3 2 0 0 , and NTU-1200/1700/2200/3200 series . The whole family of NTS/NTU are fully digital designed, with three major characteristics of miniaturization, high efficiency, and intelligence. The main features are, instantaneous peak load capacity which can reach up to 2 times of output wattage, as well as AC output voltage/frequency/power saving mode adjustment capability through the DIP switch of front panel (the idle standby consumption is 1.5W).

It s efficiency reaches up to 93%, and it can be operated within temperature range from -25~+70 . Built-in remote control, able to monitor the battery voltage and the load status of the inverter through IRC1/2/3. Not only intergrated multiple intelligent p r o t e c t i o n s , b u t a l s o p a s s e d s a f e t y r e g u l a t i o n s s u c h a s CB/DEKRA/E13/EAC/UL/RCM/FCC/CE/UKCA. Materials and components are strictly selected and 3-year warranty is provided. It is suitable for households, vehicles, yacht and remote areas without power grids.

Common application such as, lighting, air conditioning, refrigerators, hair dryers, microwave ovens , computers, televisions, hand-held power tools, motor equipment, mobile AC power... etc.
