Test conditions and notes5

1.Efficiency, AC regulation and THD are tested by 2400W load, linear load at 12.5Vdc/25Vdc/50Vdc input voltage.
2.No load dissipation at non-saving mode(Typ.): 112/124/148 for 25W, 212/224/248 for 55W.
3.All parameters not specified above are measured at rated load, 25℃ of ambient temperature and set to factory setting.
4.Internal pre-start circuit, the setup time is 8s.
5.The power supply is considered as an independent unit, but the final equipment still need to re-confirm that the whole system complies with the EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )

FAQ

What kind of output waveform does the Mean Well NTS-3200-248AU provide?

This model provides a true sine wave AC output with total harmonic distortion below 3%. That makes it a better fit for equipment that needs cleaner power than modified sine wave inverters can provide.

What are the input and output power details for the NTS-3200-248AU?

The NTS-3200-248AU is a 3200W DC-AC inverter designed for 48V DC input and 230V AC output. It also supports high surge power up to 6400W for short-duration demand.

Is this inverter suitable for demanding commercial or mobile power applications?

Yes. With 3200W continuous power, true sine wave output, and up to 6400W surge capacity, it is suited to professional applications where stable AC output is important. Buyers commonly consider this class of inverter for vehicles, field systems, and off-grid business equipment.

Can the NTS-3200-248AU work with different battery chemistries?

Yes. Mean Well specifies this model as suitable for both lead-acid and lithium-ion battery systems. That gives B2B buyers flexibility when standardizing across different DC power platforms.

What protection features are included in this inverter?

This model includes output short-circuit, overload and over-temperature protection, plus DC input low-voltage shutdown (40±1Vdc) and high-voltage shutdown (66±1Vdc). After a short-circuit, overload or over-temperature shutdown, the unit must be re-powered to recover.

Is the NTS-3200-248AU designed for harsh operating environments?

Yes. It is rated for operation from -25°C up to 70°C (with load derating at higher temperatures), uses fan cooling, and is specified for 10–500Hz, 3G vibration. These ratings make it well suited to demanding industrial and mobile installations.

Does this model support voltage or frequency selection and remote monitoring options?

Yes. The AC output voltage and frequency are selectable by DIP switch, and the unit has a built-in remote ON-OFF connector and RS-232 (RJ11) port. The IRC1/IRC2/IRC3 remote controllers and RJ11-RS232 cable are sold separately for users who want more control and status visibility.
