Electronic Ballast for 250W High Pressure Sodium/Metal Halide Lamp

タイトルまたは説明

Products description ·Full voltage design . ·Independently-developed application-specific control software, the circuit with simple character and stable performance. ·advanced frequency conversion technical, the electric ballast can automatically recognises the state of the light source, can match the optimum operation frequency for the light source, can increase the luminous efficiency of light source by *0% in the same power. ·Controlled by computer procedure, the electric ballast can formulate the dimmable strategy according to the different hours, pedestrian flow and vehicle flow of the road, can achieve multiple ***** can work when the output power reduce to *0%, It is the best choice of the energy-saving modification of road light. ·High power factor ·Wide range of operating voltage, ·Start at low voltage, ensure that the output power is constant. ·Long line driven, the lamp and the ballast can be installed separately, convenient for maintenance. ·The impact of current, ettended device life. High quality illumination, no flicker. Low total harmonic distortion, low impact on power network. ·High efficiency above *4%, remarkable energy-saving effect. ·Full protection: protection for open loop, short loop and hot lamp restart. ·Low start current, *0 minutes to restart protection (optional), able to prolong the source life Low temperature rise, wide range of operating temperature. ·Lighting protection, ensure working well in thunderstorms conditions.
