MEAN WELL NTS/NTU Series DC-AC Pure Sine Wave Inverters

Inverter Product Category

True Sine Wave Inverter Roadmap

The roadmap illustrates the evolution of true sine wave inverters:

• Old Generation: Standard-alone TS Series (TS-200 / 400 / 700 / 1000 / 1500 / 3000) and Ture Sine Wave with AC and Solar Charger (TN-1500 / 3000). Remote controllers (IRC-1/2/3) are also available.
• New Generation: Built-in type Ture Sine Wave (NTS-250P / 400P), Standard-alone Ture Sine Wave (NTS-300 / 450 / 750 / 1200 / 1700 / 2200 / 3200, under development for 1700~3200W), and Standard-alone Ture Sine Wave with UPS (NTU-1200 / 1700 / 2200 / 3200).

The roadmap is visualized on a Watt scale from 200W to 3200W.

NTU Series - Built-in UPS Function

The NTU Series offers integrated UPS functionality:

• When the AC grid is normal: The inverter uses AC by-pass to supply power to the load directly.
• When the AC grid fails: The battery converts DC power to AC power to supply the load.

This provides continuous power for connected devices.

NTU Series UPS Application – Alternate Power Supply

Example Scenario:

• A City (Normal AC Grid): AC grid is normal, AC by-pass supplies power via the inverter.
• B City (AC Power Failure): AC power fails, the inverter converts DC from the battery to AC to supply power.

General Applications

No AC Grid - Mobile AC Power Supply

• Mobile medical carts / Ambulances
• Gardening vehicles / Camping vehicles / Refrigerated vehicles
• Off-grid equipment: Industrial-grade vacuum, forklift
• Mobile power bank

With AC Grid - UPS Backup Power Supply

• Power supply in countries and regions with unstable power grids
• Office / Home backup power
• Fire protection facility backup
• Communication equipment backup
• Elevator safety backup

Common Loads

The NTS/NTU Series inverters are suitable for powering a wide range of common loads, including:

• Televisions
• Microwaves
• Lamps
• Coffee machines
• Drills
• Floor cleaners
• And other household or professional appliances.
