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

Magnetic Ballast is an iron core inductor, 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.
Coil: generating induced emf. In case of power, because there is a certain resistance coil will produce power loss, the resulting rise in temperature thermal energy ballast, the ballast is easy to accelerate aging. In order to reduce the resistance of the coil, try to use high purity copper enameled wire imports.
Silicon steel sheet: block conductor in a changing magnetic field, the conductor in the entire internal cause induced current, commonly known as "eddy", it will cause energy consumption, temperature rise. In the ballast, in order to enhance the strength of the magnetic induction cores are used, but because of the presence of eddy currents to be insulated from each other using a thin silicon steel lamination core formed, rather than the core piece, to reduce eddy current bring loss.
Bottom: fixed installation role.
Skeleton: Fixed coils, chip, easy wiring role.

Design for Long Life: Because of core ballast quality insulation material, coil core and copper wire, control gear in the EC, OM and OG series from James lighting achieve a maximum life of approximately 100,000 hours of operation, in other words about ten years of constant use at a winding temperature of 130°C (tw=130°C). The winding temparature is the ambient temperature plus the increase in temperature due to the power consumption of the unit. A change in temperature of 10°C up or down leads to a doubling or halving of the life of the unit.

Constant High Quality: Uniform high quality standards are guaranteed by the use of high-grade materials together with manufacturing processes certified to ISO 9001. Fully automatic manufacture also ensures constant reproducible quality. All the high pressure sodium ballasts are subjected to 100% final testing and safety.
