OPPO R9s is out! 1600W pixel front lens camera features outstanding

OPPO R9 series sales have exceeded 10 million, and the popularity is amazing. OPPO officially released the R9 upgrade last night - R9s, the machine brings a number of improvements, but the most important can be summarized as two aspects, one is the appearance, the second is taking pictures.

OPPO R9s continues the R9 design, with 6.6mm ultra-thin body, "condensed waistline", 1.66mm screen frame, front fingerprint, etc. For the "leucorrhea" problem of metal mobile phones, OPPO gives new Solution - micro-slit antenna. This technology turns the original 1.5 mm - 2 mm wide antenna into three antennas with a width of only 0.3 mm. The area of ​​the 6 finely-engraved micro-slit antennas is reduced by 60% compared with the R9, and the metal proportion of the fuselage is increased to 98.8%, which enhances the sense of unity of the mobile phone. Comparing the antenna processing of the Apple iPhone 7, there is no doubt that the R9s are more beautiful.

In addition, OPPO R9s also improved the Home button, the new solid-state button can not be pressed like the iPhone 7, without pressing, can be unlocked with a single touch, the user is easier to use; the addition of the hydrophobic film process improves the wet hand unlocking success. rate. Equipped with a 5.5-inch Full HD-class AMOLED screen.

In terms of photography, the OPPO R9s uses a 16-megapixel IMX398 sensor jointly developed with Sony. The innovative dual-core focusing technology increases the area of ​​each focusing pixel by 100% and the average focusing speed by about 40%. It has improved the problem that mobile phones are easy to paste. The f/1.7 large aperture light input is about 60% higher than the common f/2.2 aperture on the market. The night shot picture is clear and less noisy, and the details are more abundant. It can be said that R9s on the hardware is not worse than Samsung Note 7.

The self-timer still uses a 1600W pixel front lens to support the ultimate beauty 4.0, making the selfie more natural and clearer. The front background blur function is added, the portrait becomes more prominent, and the high-contrast light scene starts from the front-mounted HDR mode, and the dynamic range is wider, and the characters and scenery become better and clearer.

Equipped with ColorOS 3.0 based on Android 6.0 development, although the UI has not changed much compared to the previous version, many improvements have made the user experience better, such as anti-counterfeiting base stations, application avatars, and mobile phone moving. In terms of hardware, it uses Qualcomm Snapdragon 625 eight-core processor with excellent energy consumption, memory configuration of 4GB RAM + 64GB ROM, and supports 128GB of extended storage. Standard 3010mAh battery, support VOOC flash charging and 4G full Netcom.

Also released in the same period is the R9s Plus. Compared with the R9s, the screen is upgraded to 6 inches. The OIS+ optical image stabilization function is added. The processor starts with the Snapdragon 653, the running memory reaches 6GB, and the battery also increases to 4000mAh.

In terms of selling price, OPPO R9s is priced at 2,799 yuan and is available in gold, rose gold and black. It will be officially launched on October 28th. OPPO R9s Plus is priced at 3,499 yuan, and the time to market is December. Do you think that this Ryan's R9s will be better than the R9?

High Frequency AC Power Supplies

High Frequency Variable frequency AC power supply converts AC electric to pure sine waveform by through AC – DC – AC conversion, which is different from variable frequency speed controller and common AC voltage regulator.

Variable frequency power supply is mainly used to convert existing AC power network supply to stable and pure sine power supply with regulated required frequency. The features of ideal AC power supply are stable frequency, stable voltage, zero internal resistance and Sine wave form (without distortion). Variable frequency power supply is close to the ideal AC power supply, so the developed countries more frequently use variable frequency power supply as the standard supply to provide the most excellent powering environment for electrical equipment and to easily evaluate their technical performance. Major types of variable frequency power supply are: Linear Amplification and PWM Switching

VFP-H series variable frequency power supply is manufactured under SPWM mode; it is designed by MOSFET module as active component, and adopts other technologies as digital frequency division, D/A conversion, instantaneous feedback and sinusoidal pulse width modulation to make the capacity of single unit up to 150KVA. Isolated transformer used to enhance total stability, strong load applicability, high quality output waveform, and simple operation, small size and light weight. In addition, this power supply has many protective functions against short circuit, over current, over load and over heat to ensure proper operation.

Comparing to traditional frequency inverter power supply, our inverter power supply removes the transformer and frequency converter, by using pure high-frequency conversion technology, with built-in by AC/DC and DC/AC parts, our AC inverter power supply could give stable AC output with prefect output precision.
Because, our new technology does not need transformer for conversion and isolation, the power supply size can be reduced within the same output power rating, and not limited by the transformer, output frequency could reach 15 ~ 1Khz continuously adjustable.
