Digital isolators were introduced more than 10 years ago to reduce the adverse effects associated with optocouplers. Digital isolators are based on CMOS-based circuitry that can provide significant cost and power savings while significantly increasing data rates. The digital isolator is defined by the above elements. Insulation material determines its inherent isolation capability, and the material selected must meet safety standards. More and more intelligent industrial and communications equipment, providing more high-power system control and feedback, and achieve greater efficiency and reduce system cost, the market today for digital isolators UV light curing machine needs are also Growing.
Digital isolator UV light curing technology in the off-line LED driver application description:
The widespread use of LEDs and heatsinks between mechanical isolation and non-isolated drives, however, complicates the electromagnetic interference (EMI) problem and poses a potential security risk. We have adopted the micro-transformer technology, to achieve an integrated, compact and reliable off-line LED driver isolation. These innovative technologies not only allow accurate constant current control of the amplified current error signal, but also provide auxiliary bias isolation to the primary side controller, eliminating the auxiliary winding. More importantly, the various barrier functions on both sides of the barrier, such as the reference voltage, error amplifier, over-voltage protection and PFC controller, etc. are integrated. This integrated isolation provides efficient and accurate control of multi-stage LED drivers with no flicker and no lifetime limitations, enabling LED drivers to match LED bulbs in terms of lifetime and reliability.

Metal coating UV light curing

Equipment, metal coating the most common surface of the electroplating layer, spray layer, brush layer and so on. Electroplating can not only make the surface of equipment beautiful, but also equipment rust, corrosion, it is widely used in production practice. However, a large area for electroplating, electroplating equipment by the restrictions, the general factory does not attach such a workshop. Metal coating UV light curing mainly include food cans UV light curing, automotive and equipment decoration UV light curing, traffic tunnel wall UV light curing, stripping lining UV light curing, UV light curing label, casting UV light curing.
Metal coating UV light curing:
Metal coating UV light curing can improve the parts corrosion resistance, friction, wear and fatigue, and for some matrix material does not require this requirement. The performance of the surface coating depends on the properties of the substrate material, the surface finish and the coating thickness, which can result in two orders of magnitude changes in the surface friction; the friction of the soft metal coating is small and the friction of the hard metal coating Force larger. Very smooth surface and very thin coating, these effects are more obvious. The thin soft metal coating has greater wear resistance, while the thin hard metal coating has less abrasion resistance. Whether it is the kind of material, UV light curingtechnology can play a corrosion resistance, friction, wear and fatigue role.
