Recently, there have been a group of colorful C200 players with original boxes. The author thirsed after reading the price. Mainly after a while out of HiFiman has been using 6sp direct push, although the effect is not bad, but has been driving the music, then seriously affect the battery life. Buying a player at this time becomes just what you need. C200 as a rainbow in the HiFi field in a pilot product, its sincerity is there, quality will be evaluated later. However, in the field of HiFi players, domestic products are obviously too competitive, so it is not surprising that it has lost. Of course, thanks to the blessings we can not get, we can get such a cost-effective product. After some py, the author finally got a price of 300 yuan ± 20% (more or less confidential, 233). After a long wait, Shun Feng gave me a payment. Can't wait to get out of the box and see a well-packed host. The simple paper box contrasts with HiFiman's hard textured leather case. Then the family portrait. Manual, three packs of cards, host, data line, very simple configuration. It is worth mentioning that this micro-USB data cable, the connector appears to be gold-plated, and the wire has a real anti-jamming magnetic ring, may be prepared for the USB-DAC function. Unfortunately, this feature is dead, it is just a better quality microUSB 2.0 data line. Because the firmware that comes with the C200 factory has a very serious problem, when the song is cut, it will play less audio for the first two seconds, so I chose to upgrade the firmware first. Download the latest version of the firmware on the official website (in 2016.), extract the .bin firmware to the root directory of the TF card after decompression twice, select the local information, and click OK to search for the firmware. After the update, you can start using it officially. pay attention! ! ! The volume is 100% when the machine is turned on for the first time and after the firmware is swiped! ! ! Never put the earphone directly on the ear and press the play button for the first time! ! ! The first thing to say is that the interaction between the machine is not good and the function is not perfect. First of all, it doesn't have a custom playlist feature. There is only one "favorite", which is "my favorite music" that corresponds to the general player software. In addition to this list, you can only find one. Second, it does not have a quick search function and cannot be classified according to the music file information of composers, music genres, etc., which further increases the difficulty of finding songs. There is no way to display lyrics. This is fine. The most important issue is that this machine does not have a lock screen key. The author can only set a lock screen time of 10 seconds, but holding a machine for 10 seconds in the winter in the north to prevent touch is a painful experience. As a baby who is not deeply involved in the world, it is obviously less likely to deal with people. What about its own quality? Let's take a look at its overall appearance. The machine is a sloping shape, and the grip can really be. However, the strength of the cold and cool aluminum alloy casing is not high, you can see it gently flattened a piece of pressure. The side is the volume addition and subtraction and lanyard hole, I personally think that the lanyard hole does not have any eggs. The feedback on the volume keys is very comfortable, but if you can make the dial, I think it might be something else. Take a look at the bottom. They are microUSB 2.0, TF card, reset button. In about a week, I haven't encountered the need for reset. The other side of the firmware may be stability. Some people think that TF card plug in does not recognize, I used an OV 16G and a Samsung 32G orange card are OK, should be the reason for the partition, try using Android phone / ubuntu system format it. On the back of the machine, tanned leather was used to further enhance the feel. It feels like it was worthy of the 1299 listing price (laughs) Then play it. Because there is no amp in the hand, the lo mouth is not good to test. The author speaks for a bit of personal sense of hearing. The sound is very clear, there is no excessive modification, there is a sense of white water. Accompanied by Binary Acoustics EP1, ACG is very comfortable. The thrust of the machine itself is worthy of recognition. If you want to enter the HiFi field with a low budget, you can smash this car, and then with a flat head plug of about 100 yuan, you can get different results than the phone + hundred ears. Flat-faced words are very cost-effective, that is, some people do not get into the ear hole. . I tried the MX500 and it feels very mellow with the C200. Experience is better than using the iPod classic (of course, the interaction is not as good as the iPod). The C200 is commendable for its endurance. This machine has a large capacity battery of 3500mah. This parameter is more than sufficient on the phone, not to mention that it supports a HiFi player with a much lower power consumption. The author listened continuously for 4 hours at 35% of the volume, and when the camera was taken out of his pocket, the body was slightly warm, but the battery meter showed only a small amount of electricity. It is a gospel for friends who do not love charging. In short, this machine is still competitive at a price of RMB 500, especially in the price range of RMB 400 to RMB 500. It is still very easy to start at a lower price. Its excellent endurance performance and clear voice can bring a good initial experience to the newly-introduced enthusiasts, and it can also enjoy good enjoyment when paired with entry-level earbuds. Compared with the so-called HiFi phones, there is a clear improvement. If the price is beautiful, it is recommended to start with a try. High Power High Voltage Power Supplies
The High-power High Voltage Power supply is a customized high-voltage power supply family developed by iDealTek-Electronics based on the design and development of IGBT switching elements.
High Power HV Power Supplies, High Power High-voltage Power Supplies, High-Power High-voltage Power Supplies, High-Power High Voltage Power Supplies, High-Power HV Power Supplies Yangzhou IdealTek Electronics Co., Ltd. , https://www.idealtekpower.com
HP series High power high-voltage power supply is the first generation high-power HVPS designed by iDealTek-Electronics, adopting the standard 19-inch chassis structure to facilitate the integrated installation of high-voltage systems. The output power ranges from 5kW to 15kW (single unit), with the output voltage ranging from 1KV to 60kV.
HPS series ultra-high-power high-voltage power supplies are developed on the basis of HP series using internal high-power high voltage modules in parallel built in 19-inch standard cabinet with control, inverter, high voltage transformer split design structure, output power ranges from 50KW to 300KW with output voltage up to 300KV. The power supplies adopt a mixed cooling method of air cooling of the control part, water cooling and oil cooling of the main power unit. The internal module redundancy technology and perfect protection circuit ensure the excellent reliability of the power supply under high-voltage and high-power output.
Compared with the traditional linear high power High Voltage Power Supplies, our high-power high voltage power supplies of IGBT-based topology can achieve output power beyond that of the linear high voltage power supplies and also break through the ceiling where the output voltage cannot exceed tens of KV, besides the same electronic characteristics of high precision low ripple and high stability as the linear high-voltage power supplies, our high power high voltage power supplies are also featured for high efficiency, fast response characteristics that linear high voltage power supply can't match.
At present, the production of high power high voltage power supplies is difficult and the applications are diverse and scattered. Basically, they are mainly customized. The industries that have been aiding include mining gravel, ultra-high-power capacitor charging, electron beam melting, electron gun, ion acceleration, ion implantation and other cutting-edge industries.
