Overview

What it is

The MEAN WELL NTU-1700-224UN is a DC-AC inverter from the NTU-1700 series (1700 W High Reliable True Sine Wave with UPS DC-AC Power Inverter), rated 24 V DC to 230 V AC, 1700 W.

What it is used for

Runs AC equipment from a 24 V battery bank with a true sine wave output, and passes mains power straight through to the load when AC is present, switching to the battery within about 10 ms on a mains failure. MEAN WELL lists applications such as home and office appliances, off-grid solar power systems, wireless networks, telecom or datacom systems.

Key features

Built-in UPS function (AC bypass).
True sine wave output (THD <3%).
Surge power up to 3400 W.
Protections: reverse polarity, DC low alarm, DC low shutdown, over voltage; output short circuit, overload, over temperature.
Battery over discharge protection (low voltage disconnect).
Suitable for lead acid or Li-ion batteries.

Key Specifications

DC Input Voltage: 24 V DC nominal (20 to 33 V DC).
AC Output Voltage: 230 V AC default; 200, 220, 230 or 240 V AC selectable by DIP switch.
Rated Output Power: 1700 W continuous.
Surge Power: 3400 W for 30 cycles.
Output Waveform: True sine wave (THD <3%).

Buying considerations

Size the unit with headroom above the connected load and check the derating information in the datasheet for high ambient temperature or low input voltage. Other models in the same series are listed on this page.

Installation considerations

MEAN WELL treats this unit as a component of the final equipment, so approvals and EMC performance should be confirmed for the complete installation. Wiring and safety details are in the official datasheet linked below.
