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 is the Mean Well NTS-3200-224AU designed for?

The NTS-3200-224AU is a 3200W true sine wave DC-AC inverter that converts 24V DC input to 230V AC output. It is suited to commercial and industrial applications that need clean AC power from a DC battery system, including mobile, backup, and off-grid power setups. This AU version is supplied with an Australian socket configuration.

Does the NTS-3200-224AU provide true sine wave output?

Yes. The NTS-3200-224AU provides true sine wave AC output with total harmonic distortion below 3%, which is useful where stable, low-distortion output is required. That makes it a better fit for sensitive loads than inverter types that do not specify true sine wave performance.

What input and output ratings does this inverter have?

This model is rated for 24V DC input and 230V AC output, with a continuous power rating of 3200W. It also supports high surge power up to 6400W for short-duration startup demands. The AC output voltage and frequency are selectable by DIP switch within the ranges listed in the specification.

Can the NTS-3200-224AU be used with lead-acid or lithium-ion battery systems?

Yes. Mean Well specifies the NTS-3200-224AU as suitable for both lead-acid and li-ion battery systems. It also has a low-voltage alarm at 22±0.5Vdc and shuts down at 20±0.5Vdc input to help protect the connected battery source.

Is the NTS-3200-224AU suitable for demanding operating environments?

This model is built for wide-temperature operation from -25°C up to 70°C, with load derating at higher temperatures. It is fan-cooled, and Mean Well specifies it for 10–500Hz, 3G vibration. These ratings make it well suited to demanding industrial and mobile installations.

What protection features are included in the NTS-3200-224AU?

The NTS-3200-224AU includes output short-circuit, overload and over-temperature protection. It also has DC input low-voltage shutdown (20±0.5Vdc) and high-voltage shutdown (33±0.5Vdc); after a short-circuit, overload or over-temperature shutdown it must be re-powered to recover. These protections are intended to help safeguard the inverter and the connected power system during abnormal conditions.

Does this inverter support remote control or communication accessories?

Yes. The NTS-3200-224AU supports remote power on-off control and has optional remote controller accessories including IRC1, IRC2, and IRC3, which are sold separately. It also supports RS-232 communication using the specified communication cable accessory, also sold separately.

What certifications and compliance approvals does the NTS-3200-224AU have?

Mean Well lists the NTS-3200 series with approvals including CB IEC62368-1, EAC TP TC 004 and AS/NZS 62368.1; EN62368-1, UL458 and E13 apply only to particular socket types, per Mean Well's AC output socket table. EMC-related compliance includes EN55032 Class A and EN61000-4-2, -3, and -8. For buyers in regulated commercial projects, these published approvals can help with product screening and specification review.
