This barretter is suitable for high-voltage sodium lamp, mercury lamp, fluorescent lamp and other gas discharge lamp. Comparing with induction barretter, it cust down 70-90% on electricity. The lifetime of fluorescent lamp is increased by several times, and the brightness is enhanced. It can raise the power factor of electric-network so that the wattles compensation can be applied comprehensively. Compare with those barretters in which a capacitor is in parallel directly with inductor load, parallel resonance scarcely occures. In addition, the operating voltage of the currant-limiting capacitor is decreased, therefore this barretter has lower power comsumption, longer lifetime, does not have much trouble and can easily keep maintenance. |
