Precisely Set Output Current: Keep your phone close to the driver’s NFC detection area to read the data, and then set and write the desirable output current based on your needs into the driver. Merrytek NFC can largely change the output current to suit various operational requirements, as well as, achieve precise 1mA adjustment to satisfy specific energy consumption needs. It can ensure that devices are always in the best electric driver state, effectively increasing their lifetime and performance. Flexibly Control Constant Luminous Flux Output (CLO): As LED’s service life increases, its luminous flux decreases. By turning on or off the device’s CLO function and adjusting parameters, Merrytek NFC can increase current output when the luminous flux of the luminaire module diminishes, thereby ensuring a stable brightness output level, prolonging luminaire’s service life and providing users with a better lighting experience. Easily Customize Dali System: Integrated with DALI lighting system setting function, Merrytek NFC offers abundant choices for customization, allowing dimmable curve, gradual change of lighting and other effects to be easily presented. It can assign DALI addresses and handle mass devices’ address planning. The operation is simple and not prone to errors. It supports DALI grouping and scene setting. Users can create and switch between diverse scenes with one click based on actual needs, such as office mode, leisure mode, emergency mode, etc., enabling quick responses from device groups to meet complex needs of commercial and home environment. Enable Corridor Mode with One Click: For specific scene, Merrytek NFC can preset corridor mode and activate it through a connection between the phone’s NFC and devices. This mode intelligently controls luminaries or drivers based on preset time intervals and brightness levels. It ensures adequate lighting, meanwhile, effectively reduces energy consumption, providing desirable lighting solutions to corridor, aisle and other public areas. Simple and Intuitive Operation Interface: The operation interface design of Merrytek NFC focuses on users, being succinct and clear, and easy to operate. Even someone who is first introduced to it can rapidly master it in a short time. The distribution of each parameter setting option is reasonable with distinct icons and text clues. Therefore, even complex parameter settings can be completed through simple sliding and clicking, which saves time and energy. Adjust Parameters Anywhere at Any Time: As long as your mobile phone is equipped with Merrytek NFC and its NFC function is turned on, it’s possible to set parameters for compatible devices wherever and whenever.
