Deliver Stable, High-Quality AC Power Anywhere
Introducing the Mean Well NTS-300, a 300-watt true sine wave DC to AC power inverter designed for high reliability in off-grid and mobile applications. This inverter converts 12V DC power from batteries into exceptionally pure and stable AC power, making it ideal for powering sensitive electronics without the risk of damage. Its robust digital design with MCU control ensures it can handle demanding loads, with a peak power of up to 600W. The fanless design ensures silent operation, perfect for residential, commercial, marine, and automotive use.
Engineered for Performance and Safety
The NTS-300 is built to perform in harsh environments, featuring a wide operating temperature range from -25°C to +65°C and a conformal coating for added durability. It offers user-selectable AC output voltage (200 / 220 / 230 / 240VAC) and frequency (50 / 60Hz) via a simple DIP switch, providing versatile power options for various equipment. A comprehensive set of protection features safeguards both the inverter and your devices, including input reverse polarity, DC low alarm, over-voltage, and output short circuit, overload, and over-temperature protections. It is compatible with both lead-acid and li-ion batteries and includes a power-saving mode that reduces no-load dissipation to less than 1.5W.
Key Features:
- True Sine Wave Output: Ensures clean, stable power (THD<3%) for sensitive electronics.
- 300W Continuous Power: Handles a high surge power of up to 600W.
- Selectable Output: AC voltage and frequency can be easily selected via DIP switch.
- Silent Operation: The fanless design eliminates noise.
- Wide Temperature Range: Operates reliably in temperatures from -25°C to +65°C.
- Remote Control: Features a remote ON/OFF control for convenient operation.
- Comprehensive Protection: Includes a full suite of input and output protections for maximum safety.
- Battery Compatibility: Suitable for use with both lead-acid and li-ion batteries.
