Test conditions and notes5

1.Efficiency, AC regulation and THD are tested by 1650W 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.

FAQ

What is the main use case for the Mean Well NTU-2200-248AU inverter?

This model is designed to convert 48V DC input power into true sine wave AC output for applications that need clean 220V-class power. It is suited to business and industrial systems where stable AC output, UPS-style AC by-pass capability, and higher continuous power are important.

What AC output can this inverter provide?

The NTU-2200-248AU is rated for 2200W continuous output and provides true sine wave AC with THD below 3%. Its AC output voltage is factory set at 230VAC and selectable by DIP switch across 200/220/230/240VAC, with 50/60Hz selectable, making it flexible for different equipment requirements.

Does this inverter support surge loads?

Yes. This model supports surge power up to 4400W, which helps with equipment that has a higher startup demand than its normal running load. Buyers should still make sure the ongoing load stays within the 2200W continuous rating.

Does the NTU-2200-248AU include an AC by-pass or UPS-style function?

Yes, it includes a built-in UPS function with AC by-pass. That makes it a stronger choice than basic inverters when the application needs automatic support for AC source pass-through behavior in addition to DC-to-AC conversion.

Is this inverter compatible with lead-acid and lithium-ion battery systems?

Yes. The NTU-2200-248AU is stated as suitable for use with lead-acid or li-ion batteries and includes battery over-discharge protection through low voltage disconnect. It is specifically a 48V input model, so it should be matched with a 48V DC battery system.

Can this inverter be used in demanding temperature conditions?

Yes. The product specification lists a working temperature range of -25°C to +70°C, and the unit uses a cooling fan, with over-temperature and fan-lock status shown on the front panel LEDs. As with other power equipment, output derating applies at higher temperatures according to the manufacturer's curve.

What protections and monitoring features are built into this model?

The NTU-2200-248AU includes protection for output short circuit, overload, over temperature, DC input high-voltage shutdown, and battery low-voltage shutdown. It also has front panel status indicators, remote power on/off capability, and RS-232 communication support when the separate cable is ordered.
