Application: The energy efficient XLDL series of electronic ballast products of Changsha Xinglian power company, can be used in the field of commercial lighting, road lighting, plant lighting, stadium lighting, tunnel lighting, industrial lighting and other lighting, and water and other environmental protection areas. Characteristics: XLDL-HPS series of electronic ballasts have a good working parameters: Significant energy savings, significantly extend bulb life and reduce the harmonic pollution has become an important part of the green lighting project, the preferred configuration of its overall economic efficiency of high energy efficient lighting project. Own loss of small: electronic ballast power consumption 30% less than the inductance ballast, light efficiency save 8% (compared with inductive ballasts). With the intelligent dimming control system can be integrated more than 40% of the energy-saving. Lighting power constant: the input supply voltage 185V-265V (rated voltage of 220V), a wide range of changes, the output of the lamp power change
