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 Mean Well NTU-2200-124US designed to do?

The NTU-2200-124US is a true sine wave DC-AC inverter that converts 24V DC input power to 110V AC output. It is intended for applications that need clean AC power from a DC battery-based source, with a rated output of 2200W.

Does this inverter provide true sine wave output?

Yes. This model provides a true sine wave AC output with total harmonic distortion below 3%, which is useful for equipment that performs best on cleaner AC power. That makes it a stronger choice than modified sine wave alternatives for more sensitive loads.

What input and output voltage does the NTU-2200-124US use?

This version is built for 24V DC input (20 ~ 33Vdc range) and is factory set to 110V AC, 60Hz output. The specification also states that AC output voltage can be selected by DIP switch from 100/110/115/120VAC, and frequency between 50/60Hz.

How much power can the NTU-2200-124US handle?

The inverter has a rated output power of 2200W and supports surge power up to 4400W. Its overload behavior is specified as 105 to 115% load for 180 seconds and 115 to 150% load for 10 seconds.

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

Yes. The NTU-2200-124US includes a built-in UPS function with AC by-pass capability. This is a key differentiator for buyers who need inverter functionality combined with automatic AC pass-through behavior.

What battery types is this inverter compatible with?

The product is stated as suitable for both lead-acid and lithium-ion batteries. It also includes battery over-discharge protection, described as low voltage disconnect, to help protect the battery system.

Can the NTU-2200-124US be used in demanding environmental conditions?

It is designed for a wide working temperature range of -25°C to +70°C, with output derating per the derating curve. The unit also uses a cooling fan, with over-temperature and fan-lock status shown on the front panel LEDs.

What certifications does this inverter have?

The NTU-2200 series lists approvals including CB IEC62368-1, EN62368-1, UL458, E13, EAC TP TC 004, and AS/NZS 62368.1, but approvals depend on the AC socket type (UL458 applies only to the TB socket type; see the sheet's AC output socket table). EMC emissions for this 124 model are to FCC Class A.
