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.

Nice flexible silicone wire
Size: 14 gauge silicone wire 10ft and 10ft, Color: silicone wire red and black
I purchased to replace the main power cable for an Ender 3 3D printer. The original cables were the same type but had a cheap connector Midway through to allow the power supply to be removed if needed. THOSE NYLON connectors overheated, smelled and turned black. The BNTECHGO 14 Gauge Silicone Wire were a perfect replacement. No more connector and no more heat issues.

Works well, good quality
Size: 14 gauge silicone wire 5ft and 5ft, Color: silicone wire red and black
This has worked well over the last few years. Used moslty on battery leads for quadcopters. The wire and insulation has held up well, is good quality, solders fine. I have since used other BNTECHGO silicone wire as well, and not been dissapointed.

Great for re-wiring a 12/24v DC PSU for a 3D Printer
Size: 14 gauge silicone wire 10ft and 10ft, Color: silicone wire red and black
I'm familiar with this wire as it was just coming to market as I was fading out of the RC hobby back in ... well the 90's? When I got a roughly cared for and damaged CR-10 for cheap, I decided to remodel it and place the guts and gear under the frame. This wire is thick enough to wire the power plug, MOSFett, and main board with no concern for the 30 A amperage it could draw. It crimped easily, stripped cleanly and is super supple. I paired this with a 7 color pack to re-wire things to arrange plugs where I needed them to be. It's good wire and I may even use some when I dig out my old RC-10 graphite or Bo-Link fiberglass chassis...
