[Text / high-tech LED Gan Qin] Recently, the general manager of the Like Power Division Zhou Mingliang revealed to the Gaogong LED Golden Globe Award Organizing Committee that the company will bring high-efficiency and high-power waterproof LED drive power to compete for the 2015 Senior Engineers Technology Innovation Award."
According to reports, the product uses advanced PFC + LLC + synchronous rectification isolation scheme, wherein the PFC stage uses ON's latest CCM mode control integrated chip NCP1654 PFC controller. The chip overcomes the shortcomings of the early DCM PFC control chip, and adds some new functions, improves the efficiency and reliability of PFC-level circuit operation, greatly improves EMI, and reduces interference to the power grid.
"The second phase of the product uses ST's patented latest LLC control chip L6599AT, which is an improved version of the early L6598, L6599. It has its own patented high-voltage DMOS with integrated structure to replace the external recovery flash diode for high-side drive. Charging the power supply capacitor. This not only reduces the cost, but also improves the reliability of the product." Zhou Mingliang said.

In addition, the output stage uses SYNC's USPatented patented Synchronous Rectifier synchronous rectification control chip SP6018, which itself uses the "predictive" logic principle. The integrated circuit studies the previous cycle-time "predictive" algorithm, which circulates the off-time adjustment control SR to achieve maximum efficiency and avoid cross-conduction.
The product's ultra-high efficiency, compact housing design, good heat dissipation, greatly improve the reliability of the product, and has a high cost performance. All-round protection, including over-voltage protection, short-circuit protection and over-temperature protection, ensure the smooth operation of this product.
“480W LED power supply, input voltage range is 90-305Vac, and has a very high power factor.†Zhou Mingliang said that this series of products can be applied to plant lights, high pole lights, stage lighting, large venues and street lamps.
7.62MM Power+ Signal Power Connector
power connector is used in power module system. It can select the matching power + signal connector according to the need. The feature is that the number of power and signal contacts and the matching sequence can be selected arbitrarily while keeping the connector size and contact core number unchanged.
Plug (male) / socket (female) can be installed at 90 or 180 degrees. It supports mixed or independent combination of signal and power. The quantity range of power and signal is (2-16) pin and (12-128) pin respectively
Product features
High temperature resistant, glass fiber reinforced and flame retardant polyester is used as insulation material
Copper gold composite conductor with high conductivity is used, and the contact area of the conductor is plated with gold
It adopts shrapnel contact, which has the characteristics of integration, small volume, large current carrying capacity, soft plug-in, blind plug-in, self guidance and high dynamic contact reliability. This series of products can be interchanged with FCI's powerblade series and Tyco's multi-beam series
There are three sizes of center distance of power contact: 5.08mm, 6.35mm and 7.62mm
The length of power hole / signal pin can be selected in two sizes. The power rated current is 45A and the signal rated current is 2.5A
