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

When the high pressure sodium lamp supply voltage momentary fluctuations larger decline, the lamp will self extinguish, which goes out to some of the light source can not immediately restart particular attention. Certain safety factor should be considered, so that changes are not instantaneous voltage grid below a certain allowable value. Use more HPS ballast, power factor is less than 1.2) in a large area with gas discharge lamp lighting, non-ferrous metals in order to save and improve equipment utilization, compensation should be considered in order to improve the power factor, the general method is relatively centralized compensation convenient. Wire cross-section and in the choice of lighting transformer capacity, not only to calculate the electric power consumed by the light source, and should be included in the high pressure sodium ballast power loss.
