China manufacturer of magnetic ballasts for metal halide flood lights & hps flood lights

General requirements
HPS Ballasts for high pressure sodium lamp fittings, its performance and quality will have a direct impact on the life of the high-pressure sodium lamps, the luminous efficiency and self-extinguishing. High pressure sodium ballasts requirements for the power loss is small, easy to install, strong, waterproof, anti-corrosion and safety performance, can work continuously for more than 12 hours under the conditions of ambient temperature -40 ~ +45 ℃. Reference ballasts test lamp power at the rated voltage with specified test lamp power compared to the deviation should be within ± 7.5%. Must reiterate: different specifications of the high-pressure sodium lamps must be equipped with the appropriate specifications ballast, lamp ballast can not be arbitrary equipped with, especially the low-power light bulbs equipped with high-power ballast lamp operating current is too large, leading to shorten use life, and even cause the lamp burned. Coal bubble during the entire life of the ballast voltage - power characteristics curves must change in the lamp voltage and power within the limits of a predetermined.
