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 type of output does the Mean Well NTU-2200-148US provide?

This model provides a true sine wave AC output with total harmonic distortion below 3%. It is designed for applications that require cleaner AC power than modified sine wave inverters. The rated output power is 2200W, with surge power up to 4400W.

What input and output voltage does the NTU-2200-148US use?

The NTU-2200-148US is a 48V DC input inverter (40 ~ 66Vdc range) with a 110V AC factory output setting for US use. Its AC output voltage is selectable by DIP switch from 100/110/115/120VAC, and frequency from 50/60Hz. This makes it more flexible than fixed-output inverter models.

Does this inverter include an AC by-pass or UPS-style function?

Yes, this model includes a built-in UPS function with AC by-pass. That feature is specifically listed as part of the NTU-2200-148US design and is one of its main differentiators for backup power applications. Buyers looking for inverter models with pass-through capability should verify this feature, and this unit includes it.

What kinds of battery systems is the NTU-2200-148US compatible with?

Mean Well specifies this inverter as suitable for lead-acid or lithium-ion battery systems. It also includes battery over-discharge protection through low-voltage disconnect. For buyers comparing models, that makes it suitable for a wider range of DC battery-based power systems.

Is the NTU-2200-148US a good fit for demanding industrial or mobile environments?

It is built for demanding environments with a wide working temperature range of -25°C to +70°C (with derating), 10 ~ 500Hz 3G vibration rating, and a cooling fan. The NTU-2200 series is approved to safety standards including CB IEC62368-1, with UL458 applying to the TB socket version. These characteristics make it better suited for professional and commercial use than basic consumer-grade inverters.

What protection features are included in this inverter?

The NTU-2200-148US includes protection for output short circuit, overload, over temperature, and DC input high-voltage shutdown. It also includes low-voltage disconnect to help protect against battery over-discharge. Front panel indicators provide status visibility during operation.

Can this model be used for higher startup loads?

Yes, the NTU-2200-148US supports surge power up to 4400W. Mean Well also lists overload behavior of 105 to 115% load for 180 seconds and 115 to 150% load for 10 seconds. That gives it added margin for applications with temporary peak demand above the 2200W continuous rating.

Are remote control or communication accessories available for this inverter?

Yes, this model supports remote on/off control and optional remote controllers including IRC1, IRC2, and IRC3, which are sold separately. It also supports RS-232 communication using the specified communication cable, also sold separately. Those options can be useful for monitored or managed power systems.
