Cool open A2 TV live experience: domestic products can still be presented on the high-end atmosphere!



May 24 Cool Open TV Story in East Beijing Chaoyang District D

The Live Living Pavilion held a non-ecological and large-scale strategic conference. At the press conference, three 65-inch, 55-inch and 50-inch A2 series HIFI content TVs were launched.

Today Xiaobian brought the live experience evaluation to everyone for the first time.


Cool open A2 has obvious consistency with the previous generation T55 in appearance, the official called the family front face. A black frame is used on the front, and a JBL sound, metal hole structure is on the lower part. The overall look is very texture.


Cool open A2 uses a 9.9mm ultra-thin design, using a thin and thick design pattern. The silver metal frame on the side looks very high-end.


Cool open A2 on the back of a lot of bright spots, the upper part of the silver metal back plate with a rib design, very good to eliminate the large-size TV bend characteristics. The second half of the work and materials are relatively good.


A2 interface is relatively comprehensive, three HDMI2.0 interface, two USB3.0 interface to meet the daily needs.


The base is a side-inlaid "human" shape design, with the same color of the metal body.


On the screen aspect, Kukai A2 HiFi large content TV adopts a 4K UHD panel, adopts 4K resolution, supports HDR and DN screen noise reduction technology, colors and scene brightness more brilliant, and supports MEMC frame rate compensation technology.


Cool open A2 uses TV backplane space as a sound cavity, using high-quality HIFI power amplifier chips, and 8 JBL original crossover speakers. The audio and audio systems jointly created by Coocaa and JBL have achieved Class A brand audio certification. This type of sound performs better in bass, midrange, and treble. In the sense of presence and vocal dialogue, the sound level is rich and the sound is naturally mellow. In addition, the TV audio part can be disassembled as a stand-alone speaker. Cool open to develop a key Bluetooth song function, you can share mobile music and other mobile devices at any time. Only the A2 audio can match the 2800 yuan level Bluetooth speaker on the market.


Cool open A2 equipped with a 64-bit flagship TV chip - Mstar 6A 938ARM Cortex-A72 core architecture, Mali T820 graphics processor, with 2G memory + 8G flash memory, support for 128GB extended storage, support for dual-band WiFi.

At the press conference, the company officially gave the Bunting A2 Bunny up to 65008. This score can be said to be one of the best in the current smart TV running points. Of course, the TV performance is not as powerful as the official ones. After confirming the depth of evaluation of TV series Xiaobian.


Cool open A2 adopts cool open 64-bit cool open system developed by Kuco, which is more optimized than previous UI design. It is more reasonable to deal with the section and the operation is more convenient.


Coolo A2 is equipped with a GITV broadcast control platform and expands its resources in many ways. Cool Open has in-depth cooperation with iQiyi and Penguin TV in terms of film and television, educational Zeyuzhi education and Yifang education, and the mall has combined shopping around the city.


When purchasing this series of products, a two-year TV version of iQiyi is worth RMB 598. Members can enjoy high-quality services such as free viewing of cinema lineups, ultra-high definition video resources, and content source line broadband.


In addition, Kukai has also made proper arrangements for the logistics and after-sales aspects of the purchase of TVs. Collaboration with SF Express will allow you to place orders on the same day and deliver it before 12am the next morning. Skyworth's 4950 after-sales outlets nationwide provide a complete guarantee for Kukai's A2 after-sales service.


In terms of selling price, the A2 HIFI big content TVs are 65, 55 and 50, which are priced at 6,999 yuan, 4,999 yuan and 3,499 yuan respectively. Although compared with the Internet TV of the same size on the market, the price is slightly more expensive, but Xiao Bian had to remind the parents, a penny, a lot of high-tech accumulated, this price is very intimate. PS: Each cool open A2 HiFi big content TV contains 2 years Kiwi VIP member service worth 598 yuan.

Appointment time: May 15th, 2016, 5:00 pm to June 5th, 24:00 pm, 50 吋 reservation address = Jingdong

Time to buy: 0:00 on June 6, 2016.

In general, the cool open A2 series TVs are taking the high-end route, from the design to the hardware equipment, and then to the film and television resources have exceeded a large part of similar products. The high-end atmospheric JBL audio has become a symbol of this series of products, cool open A2 series TV has become a new high-end domestic product synonymous.

Surge Protection Device SPD

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.
