    NDS products stand out for their high quality construction and design. The NDS SM600 12V to 240V inverter 600W is a modified sine wave DC to AC inverter that provides high performance and reliability, maximum safety, and, crucially, quiet operation. NDS inverters are widely used in RVs, cars, and in emergency vehicles around the world, where these qualities are essential. Living in your camper, peace of mind about your core systems is indispensable, and this inverter provides exactly that. We also stock a 24V version.

    Superior performance

    This NDS 12V to 240V inverter 600W boasts an exceptionally high yield of up to 93% when converting from AC to DC. What’s more, NDS inverters operate with some of the lowest self-consumption figures on the market. This means that the amount of power the device itself uses during operation is exceptionally low. This is achieved through the quality of the construction, such as the high conductivity connection bars installed in every NDS pure sine wave inverter.

    Excellent build quality

    High quality connections are soldered directly onto the board with high conductivity bars. This construction avoids voltage drops and power losses, and reduces energy consumption. Meanwhile, the integrated mounting brackets allow easy and safe installation in any position, so you can really get creative when space is limited. This 12V to 240V inverter comes supplied with all the cables you’ll need to install it, specific to the power of the device.

    Safe and sound

    NDS design their inverters with the following safety features as standard:

    • Soft starter protection
    • Overload protection
    • Short circuit protection
    • Reverse polarity protection
    • Over temperature protection
    • Low battery alert

    Modified sine wave explained

    A modified sine wave inverter uses square waves to generate an approximation of the sine wave output that comes out of mains sockets in your home. This more basic mode of operation makes modified sine wave inverters cheaper than their pure sine wave counterparts. The quasi-sine wave works fine for simpler electronics, such as lighting, kettles, hair dryers, and blenders, but may shorten the lifespan of more sensitive electronic devices. You can read more about modified and pure sine wave inverters on our handy guidebook page.
