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

Magnetic Ballast is an iron coreballast, inductance coil when the nature of the current changes, the magnetic flux induced in the coil will change, and thus the induced electromotive force in a direction opposite to the direction of the current, thereby preventing the current changes.
Rectifier is a rectifier unit, simply means that the AC (AC) into direct current (DC) devices. It has two main functions: first, the alternating current (AC) into direct current (DC), filtered and supplied to the load, or the supply of inverters; secondly, to provide battery charging voltage. Therefore, it is at the same time play the role of a charger.
