FAQ
What is the Mean Well NTS-750-212AU used for?
The NTS-750-212AU is a 750W true sine wave DC-AC inverter designed to convert 12V DC input into 230V AC output. It is suited to business and mobile power applications that need mains-style AC power from a 12V battery system.
Does this inverter produce a true sine wave output?
Yes. The NTS-750-212AU provides a true sine wave AC output with total harmonic distortion below 3%. That makes it a better fit for equipment that expects clean AC power compared with modified sine wave inverters.
What are the main electrical specifications of this model?
This model is rated for 750W continuous output and supports surge power up to 1500W. It uses a 12V DC input and this AU version is configured for 230V AC output, with output voltage and frequency selectable by DIP switch within the listed ranges.
Can the NTS-750-212AU work with different battery types?
Yes. Mean Well specifies this inverter as suitable for both lead-acid and lithium-ion battery systems. It also monitors the DC input, giving a low-voltage alarm at 11V and shutting down at 10V (restart at 12.5V).
Is this inverter suitable for demanding temperature conditions?
Yes. The product is specified for a working temperature range of -25°C to +70°C, with load derating at higher temperatures per Mean Well's derating curve. It is fan cooled and shuts down its output on over-temperature.
What protection features are included in the NTS-750-212AU?
This inverter includes protection for output short circuit, overload, DC input low and high voltage (shutdown at 10V and 16.5V), and battery reverse polarity via internal fuse. It also has over-temperature shutdown and front panel status LEDs for operating condition monitoring.
Does this model support remote operation or accessories?
Yes. The NTS-750-212AU supports power on-off remote control. Mean Well also lists compatible remote controller accessories such as the IRC1, IRC2, and IRC3, plus an optional carry handle sold separately.
