MEAN WELL NPB-450 series features 2x ultra-wide voltage, the ability to charge multiple types of batteries in one machine (exclusive patented intelligent voltage detection charging1), flexible user-defined charging parameters, international certifications, safety, durability as its 5 major features, making it a universal intelligent charger. Since its launch 2 years ago, it has received widespread acclaim; in order to meet the demand for more convenient and quick adjustment of charging parameters, we are presenting the NPB-450-NFC series: 450W intelligent charger equipped with near-field communication (NFC) for patented wireless communication2 in close proximity.

The NPB-450-NFC is an expanded series based on the original NPB-450, while retaining most of its functions; the main difference lies in a simpler and quicker method for adjusting charging parameters. With the MEAN WELL app on a smartphone, users can conveniently make near-field adjustments to the charging parameters, regardless of whether the charger is powered through AC or not. In contrast to the NPB-450, which requires connection to a computer via the SBP-001 programmer for configuration, the NFC solution offers a straightforward and convenient way of setting parameters. The NFC model eliminates the need to purchase an additional SBP-001 programmer and eliminates the use of any communication cables, significantly enhancing usability and reducing costs. Additionally, this product has passed the IEC/EN/UL62368-1 information class safety certification, ensuring secure usage, making it a highly cost-effective and versatile smart charger. It is suitable for charging devices such as unmanned forklifts, automotive overhead cranes, floor scrubbers, lawnmowers, mobile robots, campers, electric motorcycles/bicycles, unicycles, scooters, and more.
