Test conditions and notes6

1.Efficiency, AC regulation and THD are tested by 75% load, linear load at 25Vdc/50Vdc/400Vdc input voltage.
2.All parameters not specified above are measured at 25Vdc/50Vdc/400Vdc input and 25℃ of ambient temperature and set to factory setting.
3.The tolerance of each voltage value by models is: 224→±0.5V; 248→±1V; 2380→±5V.
4.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)
5.Saving mode only activates when the unit is used independently and the RPL switch is in the ON position.
6.During withstand voltage and isolation resistance testing, the screw "A" shall be temporarily removed, and shall be installed back after the testing.

FAQ

What is the Mean Well NTN-5K-248CAN designed to do?

The NTN-5K-248CAN is a multi-function unit that combines an AC-DC charger, a DC-AC true sine wave inverter for the load, and an AC bypass function for the load. It is intended for high-power 48V battery-based systems that need reliable 230V AC output in one integrated platform.

What are the main output and power capabilities of this inverter?

This model is rated for 5000W continuous power, 5750W for 3 minutes, 7500W peak for 10 seconds and 10000W surge for 30 cycles. It provides pure sine wave output with THD below 3%, which is important for demanding electrical loads.

Can the NTN-5K-248CAN be used in larger or expandable power systems?

Yes. Up to 6 units can be connected in parallel on the AC output using the built-in active current sharing function; total output current must not exceed the rated current per unit x number of units x 95%. Three NTN-5K units can also be set by DIP switch for 3Ø 4-wire output.

Is this model compatible with different battery types?

Yes, the NTN-5K-248CAN is compatible with both lead acid (flooded, Gel and AGM) and li-ion batteries. That makes it suitable for a wider range of industrial, backup power, and energy storage applications using a 48V battery system.

Is the NTN-5K-248CAN suitable for harsh or enclosed environments?

This model has a working temperature range of -30 to +70 degrees C, with load derating at higher temperatures per the derating curve. Working humidity is 20% to 90% RH non-condensing and it is vibration-rated to 10-500Hz, 3G, which suits enclosed or industrial installations.

What monitoring and control options are available on this inverter?

The NTN-5K-248CAN includes built-in Modbus-RTU via RS-485 and CAN bus communication for system monitoring and integration. It also supports built-in remote ON/OFF control, and optional intelligent controllers such as the CMU2E and CMU2E-R are available separately.

What protection features are included in the NTN-5K-248CAN?

This model protects the DC input against reverse polarity, low voltage (alarm at 44V, shutdown at 38V) and high voltage (alarm at 62V, shutdown at 66V). On the AC output side, it includes short circuit, overload, and over temperature protection, plus a 35A circuit breaker, to help safeguard the unit during abnormal conditions.

What certifications and warranty come with this model?

The NTN-5K-248CAN is approved to CB IEC62368-1, UL62368-1, CSA C22.2 No. 62368-1, TUV BS EN/EN62368-1, AS/NZS 62368.1 and EAC TP TC 004, with EMC emissions to EN55032 and FCC Class A. The spec sheet does not state a warranty term, so please confirm warranty coverage with us before ordering.
