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

HPS ballast, before the magnetic core is designed, the shape of the rear side of the projection "E" type hexagonal plan projection and intermediate grooves integral structure having a coil, the shape of the choke coil core coil groove adapted to the shape of the groove and placed in the coil, the yoke is a horizontal cross-sectional plan view shape of the core of the same shape projected thin plate and the cover tightly together in the top surface of the core. Therefore, the core and the yoke choke coils are essentially the envelope on the inside, only makes the high pressure sodium ballast in each direction of the magnetic field have been fully utilized, magnetic flux leakage phenomenon greatly reduced, and because the magnetic core and the design of the yoke structure are integrally
