You often come across the term "microcontroller control," but what exactly is a microcontroller, and what are the benefits of microcontroller control in NPB Series products? Let me explain! A microcontroller (MCU) is a computer used to control embedded electronic devices. By incorporating an MCU, it becomes possible to finely control the product using the program written into the microcontroller. In our product, the built-in MCU controls the "automatic adjustment of charging voltage according to battery voltage." This control program allows for applying a charging voltage that corresponds to the battery's specifications and charging status, enabling the battery to be fully charged without putting a load on it. This helps prevent battery degradation due to issues like cell imbalance, extending its lifespan and reducing costs related to adjustment, setup time, and battery replacement. Additionally, as an option, customers can also adjust settings and choose charging methods from their PC. In addition to the microcontroller control introduced here, there are many other excellent features and characteristics. For more detailed specifications and features, please download the product page or catalog, or feel free to contact us.

Surge power refers to the "instantaneous" acceptable power value that can be received from a load. Unlike rated output (continuous output), it is the power output (instantaneous output) that occurs momentarily. When powering on electrical equipment, a large current flows momentarily, exceeding the rated current value. This phenomenon is called inrush current, and surge power is required as an allowable value that can accommodate this inrush current. With the surge power capability of the NTS Series set to twice the rated output power, it has become a new advantage that allows for the introduction of inverters suitable for the rated power consumption of the load, rather than for inrush current, enabling use with minimized size and capacity. ▲Note▲ You cannot use the range from rated output to surge power value. Please use it with the appropriate rated capacity for the load. Surge power is instantaneous output, so it cannot continuously output that value. Using a load outside the range of rated output can lead to inverter failure. Understanding the load side, including inrush current, is essential for selecting an inverter. If you have any questions, please feel free to inquire about the load you will be using.

One of the features of our product "Portable Power Box" is its "completely waterproof design (equivalent to IP65)." In this article, we will explain what IP means and how excellent IP65 is! IP stands for Ingress Protection, which is a standard set by the IEC that indicates the degree of dust and water resistance. The first characteristic letter following IP represents dust resistance, while the second characteristic letter represents water resistance. The degree of dust and water resistance is classified into grades, with levels ranging from 0 to 6 for dust and 0 to 8 for water, indicating that a higher grade signifies better ingress protection capabilities. (In Japan, the IP table is standardized by the Japanese Industrial Standards and the Japan Electrical Manufacturers' Association.) Based on the above, our product, which is equivalent to IP65, has a "completely dustproof structure" and possesses high dust and water resistance, meaning it is "not adversely affected by direct water jets from any direction." With its excellent dust and water resistance and complete sealing, it can be safely used in various environments, whether indoors or outdoors, even in conditions with rain, wind, or dust. We also offer many other products with excellent features, so please feel free to download our product pages or catalogs for more information, or contact us with any inquiries.
