Tuner4TRONIC® Field is a free app developed by OSRAM for Android devices. It enables the programming of compatible OSRAM NFC LED drivers wirelessly and without mains voltage, allowing for easy installation and maintenance of indoor and outdoor luminaires. With Tuner4TRONIC® Field, users can adjust certain luminaire settings according to specific needs and within a predefined range set by the luminaire manufacturer. For indoor and outdoor applications, users can adjust the light output in percentage, lumens, and milliamperes, edit constant lumen output (CLO), and toggle dimming on/off for outdoor drivers. Additionally, users can enter luminaire info (text, GPS, QR), copy and paste configurations from one LED driver to another, and load LED driver configurations from emails. The app also provides a report of an LED driver’s configuration and monitoring data (D4i), which can be sent via email as a CSV file. The app supports English, French, German, Italian, and Spanish.
