Dimmable Electronic Ballasts for Fluorescent Tubes

In an ongoing effort to reduce our carbon footprint on the environment, MARLEX Engineering Inc. has developed a series of dimmable electronic ballasts for use in building occupancy management and daylight harvesting applications. Our designs incorporate industry standard control interface methods for communication with the ballasts such as the Digitally Addressable Lighting Interface (DALI) and control by 0-10V DC voltage.

The light output of the fluorescent tubes can be adjusted by instructing the ballast to raise or lower the brightness to meet immediate illumination requirements around a specific light fixture. Energy savings can be realized by reducing the light output when full brightness is not required. Our ballast designs provide ultra low total harmonic distortion, stable light output and near unity power factor operation.
