Mean Well NTU-1200-212AU True Sine Wave DC-AC Inverter 1200W 200V out 12V in with AU Socket

The NTU-1200-212AU is a true sine wave DC-AC inverter designed to deliver 1200W continuous power. This model converts 12V DC input to 200V AC output and includes an AU socket. Its output waveform has THD below 3%, which is important for equipment that requires clean AC power.

This model is suited to business and industrial applications that need 200V AC power from a 12V battery-based system. Typical use cases include mobile power, backup power, and equipment that benefits from true sine wave output. The built-in UPS bypass function also makes it relevant where AC pass-through capability is needed.

Yes, Mean Well specifies that this inverter is suitable for both lead-acid and lithium-ion batteries. That gives buyers more flexibility when selecting or standardizing battery platforms. It also includes battery over-discharge protection through low voltage disconnect.

The NTU-1200-212AU is rated for 1200W continuous output and supports surge power up to 2000W. Mean Well also specifies overload behavior at 105 to 115% load for 180 seconds and 115 to 150% load for 10 seconds. This helps it handle short-duration startup demands better than an inverter with only a flat continuous rating.

This inverter supports selectable AC output voltage ranges of 100/110/115/120VAC and 200/220/230/240VAC. Mean Well also states that output voltage and frequency are selectable by DIP switch. For this specific model, the nominal listed output is 200V AC.

It is designed to operate across a wide temperature range of -25°C to +70°C, subject to the output derating curve. The unit also features conformal coating and a temperature-controlled cooling fan, which support reliability in harsher operating conditions. Buyers should still confirm that their enclosure and thermal conditions match the product's rated operating environment.

The NTU-1200-212AU includes protections for short circuit, overload, and over voltage, along with battery over-discharge protection. It also has front panel indicators for operating status and supports RS-232 communication. Remote controller accessories are available separately for applications that need external control access.

Mean Well lists CB IEC62368-1 approval for this model, with design reference to AS/NZS 62368.1. EMC compliance includes EN55032 Class A and BS EN/EN61000-4-2,3,4,5,6,8,11. The inverter is backed by a 3-year warranty.
