1.Efficiency, AC regulation and THD are tested by 1350W load, linear load at 12.5Vdc/25Vdc/50Vdc input voltage.
2.No load dissipation at non-saving mode(Typ.): 112/124/148 for 16W, 212/224/248 for 29W.
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-1700-148US designed for?

The NTU-1700-148US is a true sine wave DC-AC inverter that converts 48V DC input to 110V AC output for powering AC equipment. It is built for higher-power applications that need up to 1500W continuous output and also includes an AC by-pass function for UPS-style operation.

What type of AC output does this inverter provide?

This model provides a true sine wave AC output with total harmonic distortion below 3%. That makes it a better fit for sensitive electronics and loads that benefit from cleaner AC power compared with modified sine wave designs.

What are the input and output ratings of the NTU-1700-148US?

This inverter is rated for 48V DC input (40~66VDC range) and 110V AC output, with 1500W continuous power. It also supports surge power up to 3000W, which helps with loads that draw extra power briefly at startup.

Does the NTU-1700-148US support battery backup style operation?

Yes. This model includes a built-in UPS function with AC by-pass capability, which is one of its key differentiators. It also includes battery over-discharge protection to help protect the connected battery system from low-voltage conditions.

Is this inverter compatible with different battery chemistries?

Yes, the NTU-1700-148US is suitable for both lead-acid and lithium-ion batteries. The product data specifically lists support for those battery types, making it more flexible for industrial, mobile, and backup power applications.

Can this inverter be used in demanding temperature conditions?

It is designed for a wide operating temperature range of -25°C to +70°C, subject to the output derating curve. It also uses a built-in cooling fan and is rated for 10~500Hz, 3G vibration, which supports use in tougher operating environments.

Can the output voltage and frequency be adjusted on this model?

Yes. The AC output voltage and frequency are selectable by DIP switch: 100/110/115/120VAC and 50/60Hz, with a factory default of 110VAC/60Hz. The 200/220/230/240VAC settings are offered on the 2xx models of the NTU series, not on this 110V output model with a US socket.

What protections and certifications does the NTU-1700-148US include?

This inverter includes output short circuit, overload, over temperature, DC input over-voltage (66±1VDC shutdown), and battery over-discharge protection. It is also listed with safety approvals including CB IEC62368-1 and BS EN/EN62368-1, with EMC emission to FCC Class A.
