Online shopping has become more and more a lifestyle, from clothing to home appliances, as long as the needs of life can be bought online, there are many brands of television can also be purchased from the network channels, compared to the traditional channel network shopping You can't touch it. You can only understand it through the cold text description. Then it is especially important to practice a pair of eye-catching eyes!
Having said that, there are also some drawbacks to buying TVs on the e-commerce platform. After all, there is no physical experience. It is based solely on pictures and text descriptions to determine whether they are available for purchase. Therefore, for the purchase of TVs in such e-commerce platforms as Jingdong Mall, Tmall Mall, and Suning Tesco, it is necessary to pay attention to some purchase errors.
Compare the prices of several home appliance merchant websites
For TVs, such as home appliances, the prices between different e-commerce providers may differ. The same product may have a price difference of several hundred or even thousands of dollars. Therefore, we must first compare the good prices in online shopping. At the same time, the delivery and after-sales service of each e-commerce may be different. For example, some use self-built logistics while others use third-party logistics. These are places we need to pay attention to.
The first time to sign for damage
TVs are fragile items, especially if the screen is very fragile. Accidentally, it will cause the screen to break. This is also the easiest way to transit. Therefore, after the television is delivered, the goods will be unpacked and inspected at the first time so as to avoid subsequent problems and the responsibility cannot be determined.
Check if the TV interface is available
In addition to the TV screen, the TV's interface is also relatively fragile. Long-distance shipments, plug-in trials, etc. may affect the TV interface, may be poor contact, or because the factory equipment is not connected with the thread, may be inserted There is no reaction on the thread head, so check them one by one.
Make sure the TV is complete with accessories
Carefully read the instructions on the TV, pay attention to the name and quantity of the accessories brought by the TV, and avoid dropping some parts due to negligence, to prevent businesses from finding businesses again, which takes time and effort.
When ordering, you should learn more about TV parameters and after-sales
Since there are many types of products on the Internet and the prices of different configurations are also different, it is necessary to carefully check whether the selected models and sizes are the same when placing orders. In addition, what kind of situation can be returned, don't wait to pay the money to negotiate, communicate, it is a little troublesome.
In general, for online merchants, there will be the same situation as physical stores. Sometimes businesses often exaggerate and one-sided publicity, leading consumers to be easily misled, and often spend a lot of money and buy one. Not suitable for your own TV. For this reason, when it comes to online shopping, it is still necessary to consider in many aspects and do everything.
Smart TV/box information can focus on smart TV information network sofa butler (http://), China's influential TV box and smart TV website, providing information, communication, TV boxes, smart TVs, smart TV software, etc. Answering questions.
The whole series linear power supply adopts industrial-grade metal chassis, pure copper AC/DC multi-insulation high-voltage transformer with varnish treatment, high-reliability multi-transistor filter loop, ensuring the power supplies can run for a long time at full load with high stability, high accuracy, and ultra-low ripple electronic characteristics, equipped with a complete protection circuit, which can better ensure the reliability of the linear power supply itself and the safety of the customer's load.
The output voltage and current can be adjusted by the 10-turn potentiometer with scale and lock on the front, equipped with 4 1/2-digit high-resolution LED meters for output value reading, and RS communication interface can also be added for remote control and monitoring of linear power supplies.
This series of linear high voltage power supplies are mainly used for gas discharge, high-voltage electronic tubes, and can also be applied for other electronic components burn-in test.
Because the output this power supply has HV, the output MUST be connected to the chassis for fixed grounding to ensure the personal safety of the user.

High Voltage Linear Power Supplies
HVLP series Linear High Voltage Power Supplies are High-voltage DC Power Supplies that achieve AC/DC conversion through power frequency transformers and transistor loop control. Compared with switching high voltage power supplies, linear high-voltage power supplies have higher stability, higher accuracy, and lower output ripple. And the most important, because of the use of the power frequency AC/DC conversion principle, the linear power supply has no high-frequency radiation interference, and it is especially suitable for use in places with restrictions on EMC and EMI.
The whole series linear power supply adopts industrial-grade metal chassis, pure copper AC/DC multi-insulation high-voltage transformer with varnish treatment, high-reliability multi-transistor filter loop, ensuring the power supplies can run for a long time at full load with high stability, high accuracy, and ultra-low ripple electronic characteristics, equipped with a complete protection circuit, which can better ensure the reliability of the linear power supply itself and the safety of the customer's load.
The output voltage and current can be adjusted by the 10-turn potentiometer with scale and lock on the front, equipped with 4 1/2-digit high-resolution LED meters for output value reading, and RS communication interface can also be added for remote control and monitoring of linear power supplies.
