Speaking of this new “entertainment projectâ€, after moving in from a new home, the idea of ​​buying a TV began to talk about: At that time, the problem of buying a TV set had been repeatedly tangled on the Internet. Occasionally, a piece of speech from a colleague of the company gave way. I found a new world: “You can look at the projector that we purchased from our company. I think it's good to use it at home!†I woke up and dreamed that I’ve been distressing about the size of the TV. , 60-inch or more prices generally exceed the budget, or pay instalments, or retreat for a smaller one; this time I have a new idea: the unit purchased the projector for commercial use, then in The reliability and stability aspects are inevitably excellent, and I recall that Wang Xiao of the Purchasing Department mentioned that the price of this projector is actually not high, which is less than half the price of the previous TV.
Say it and work hard, find a colleague and borrow a projector to start testing in his own office; this projector happens to be the latest work of Microwhal Technology, which is specialized in the development of high-definition internet TVs. It's no wonder that the pain points of TV users are so well-placed, because they know what consumers want, and at the moment, I want a living room multimedia center that is capable of audio-visual entertainment in the whole family. This tiny whale intelligent projection F1 in the end Can you do it? "Two steps" will know!
The first time I saw this box, I was quite surprised: so small? Hands can be easily lifted, the whole machine weighs more than 2 pounds, looks very simple and integrated design, the top panel uses a metal wire drawing process, looks full of texture and technology, surrounded by a dense heat sink design Although the projector uses a new era of LED light source, there is no need to replace the light bulb, but after all, to create a huge screen effect, so although the whole 100-watt power control already already very good, but in order to ensure long-running The stability is equipped with multi-point cooling fins and intelligent dual air cooling system.
In the process of office testing, what actually surprised me most is the projector's powerful brightness characteristics. The brightness of up to 1200 ANSI lumens allows the projector to achieve HD projection as usual during the day, completely breaking the previous projector must pull. The flaws in the curtains are practical for those who want to use them in their own living room, and it is said that this projector has a long lifespan of 150,000+ and a 15% energy saving. It can be said to be a small body and large energy. It is less typical.
After some hard work, I basically figured out the basic characteristics of the F1. After I was very satisfied, I successfully placed an order and sent it to my home. Later, after a series of explorations, I completely grasped the F1. With all the features and personalities, there is now a great opportunity for family gatherings today! When my parents arrived at home, they began to vomit that they hadn’t bought a TV yet. I didn’t say anything, I only lighted up the machine, and then they were dumbfounded. At this time, I’d like to offer something for my dad. The hobby, I can not clear, I picked up the voice smart Bluetooth remote control, and said softly "Peking Opera Susan three solutions."
The projector immediately searched out as many as 20 different versions of video resources. At this moment, Dad could not describe himself as “stunnedâ€. He could only say that happiness was too sudden. He had forgotten to discuss with me how this was achieved. , began to concentrate on investing in Peking Opera; it is worth mentioning that, in addition to the search voice search video resources, you can even voice control: fast forward 10 minutes, backwards 5 minutes, fast forward to 13 minutes and 14 seconds ... ... and many more.
How's the weather today? How is the market today? Tell me a joke! For the switching function, it is even more appealing. If you want to adjust the picture, call “focusâ€. If you want to switch to wifi audio mode, just call “sound†or call “projection†and cut it back.
After the oldest sister arrived, Dad’s Peking Opera finally came to an end. The older sister said that she had downloaded a local animation on her mobile phone. I could give the two kids a look. I said no problem, use your mobile phone WiFi connection. Projector, even if the family does not have a net, can also cast screen, although my older sister knew that I had a new "toy" but she did not expect such a user-friendly function, because the projector of their unit is not connected to the Internet, but absolutely Can't play the screen.
After a full meal, the family is down on the sofa, enjoy the large natural unavoidable, the large screen never experienced at home, coupled with high-power professional Dolby DTS audio horn, really is a family ultimate audio-visual feast , And this kind of experience is the effect that the TV in the previous plan cannot achieve, and supports the wireless transmission protocol of MIMO technology. Even if you watch 1080P HD video online, there is no pressure, the transmission is stable and fast, and the signal strength is also very good. which performed.
After playing this micro whale F1 projector in my home, my dad seemed to find a "friend". I like to use my voice to search for my favorite Beijing opera works. All of my collections of discs don't care, he said. Convenient, Kazakhstan, who said it is not, but you don't want everyone to praise how good our projectors are, how low-key, low-key!
postscript:
After using it for a period of time, I must say that this micro whale F1 has been fully integrated into our daily life and it is a powerful all-rounder. It is time for the TV to look at the TV drama “Ode to Joy,†but it is the home theater. At the time, it was the Peking Opera masters, and sometimes the game consoles, and sometimes the wifi network streaming media speakers... etc.; some people asked what would happen if humans did not have “mobile phones� Then I would also like to ask: If our family does not have this projector, what would it be like? There are thousands of answers, but my favorite is precisely this one!
Product Description
SPD Surge Protective Device,Lightning Surge Protector
Surge Protection Device (SPD)
It is a device used to limiting instant surge voltage and discharge surge current, it at least including a non-linear component.
Surge protective Device Model Selection
With the impact of international information flow, the rapid development of microelectronic science and technology, communication, computer and automatic control technology, make the building start to go for high quality, high functional area, formed a new building style-intelligent building. As inside the intelligent building there are lot of information system, <<Building lightning protection design norm>> GB50057-94(2002 vision)(hereafter brief as <<lightning protection norm>>) put forward the relative requirement to install the surge protective device, to ensure the information system safely and stable running.
SPD essentially is a equipotential connection material, its model selection is according to the different lightning protection area, different lightning electromagnetic pulse critical and different equipotential connection position, decide which kind of SPD used in the area, to achieve the equipotential connection with the common earth electrode. Our statement will based on SPD's maximum discharge current Imax, continuous operating voltage Uc, protection voltage Up, alarm mode etc.
As per << Lightning Protection Norm>> item 6.4.4 stipulation "SPD must can withstand the expected lightning current flow and should confirm to the additional two requirements: the maximum clamp voltage during surge across, capable to extinguish the power frequency follow-on current after lightning current across." That is the value of SPD's max. clamp voltage add its induction voltage of two ends should be same with the system's basic insulation level and the equipment allowed max. surge voltage.
SPD for Power Supply System Series Selection Guide
The installation of SPD at each lightning protection zone, according to the standard of low voltage electrical appearance, make classification of electrical equipment in accordance with the over voltage category, its insulation withstand impulse voltage level can determine the selection of SPD. According to the standard of low voltage electrical appearance, make classification of electrical equipment in accordance with the over voltage category as signal level, loading level, distribution and control level, power supply level. Its insulation withstand impulse voltage level are:1500V,2500V,4000V,6000V. As per to the protected equipment installation position different and the different lightning current of different lightning protection zone, to determine the installation position of SPD for power supply and the break-over capacity.
The installation distance between each level SPD should not more than 10m, the distance between SPD and protected equipment should as short as possible, not more than 10m. If due to limitation of installation position, can't guarantee the installation distance, then need to install decoupling component between each level SPD, make the after class SPD can be protected by the prior class SPD. In the low voltage power supply system, connecting an inductor can achieve the decoupling purpose.
SPD for power supply system specification selection principle
Max. continuous operating voltage: bigger than protected equipment, the system's max. continuous operating voltage.
TT System: Uc≥1.55Uo (Uo is low voltage system to null line voltage)
TN System: Uc≥1.15Uo
IT System: Uc≥1.15Uo(Uo is low voltage system to line voltage)
Voltage Protection Level: less than the insulation withstand impulse voltage of protected equipment
Rated discharge current: determined as per to the lightning situation of the position installed and lightning protection zone.
