Ant miner is the first cryptocurrency miner brand in the world with a market share of about 70%. The mining machine is developed by bitmainland and has a patent in mainland China. At the beginning, ant miner had only bitcoin miner. Later, its business expanded to other cryptocurrencies, such as Ethereum, dascoin, Leyte, Monroe, etc
ant mining machine adopts ASIC chip designed by bitcontinental, which is proced by TSMC. All chips are made of BM prefix. Each miner has three to four circuit boards, and there are dozens of chips on the circuit board. Therefore, each miner can only be used to mine one or more cryptocurrencies using the same algorithm
ant mining machine needs special mining software, and can not use third-party software. In addition, because of its high power, the ant miner also needs to be used with a special fire ox
The ant miner is often criticized as monopolizing the cryptocurrency mining instry e to its 70% market share, which goes against the purpose of cryptocurrency decentralization. Because Monroe was worried that the mining machinery would monopolize the mining market, Monroe announced to change the mining algorithm a few days after the launch of Monroe (X3 model) despite the opposition of Monroe community, so that all mining machinery could not be used to mine Monroe. Bitcontinent also encountered the failure of its first proct herethe ant miner will use a lot of electricity and proce a lot of waste heat in the process of operation. This leads to a large amount of electricity being consumed for mining or cooling, causing a lot of social criticism. Too much ant mining machine at the same time also led to fire and power failure, causing social inconvenience
when you buy a board, there will be different drivers for different businesses, and they may not be able to use them. When you buy a board, the general businesses will tell you how to connect and how to set it. You can learn from the businesses. If you still don't understand, you can go to UU Zhongchuang to have a look. There are more engineers. If you read more, you will understand.
if it is helpful, please adopt it.
The working principle of inverter welding machine is that the three-phase power frequency (50 Hz) AC network voltage is first rectified and filtered by the input rectifier, and then converted into DC, and then through the alternating switching action of high-power switching electronic components (SCR, GTR, MOSFET or IGBT), it is inversely converted into intermediate frequency AC voltage of several kHz ~ tens of kHz, At the same time, the voltage is reced to several tens of V suitable for welding by transformer, and then rectified again, and the stable DC welding current is output by reactance filtering
When welding, the circuit is closed, because the circuit is closed, the current in the whole closed circuit is equal everywhere; Because the resistance is not the same everywhere, especially in the unfixed contact, the resistance is the largest, which is called contact resistance in physicsaccording to the thermal effect law of current (also known as Joule's law), q = i2rt, if the current is equal, the higher the resistance, the higher the heat. When welding, the contact resistance between the electrode contact and the metal body to be welded is the largest, so the heat generated in this part is naturally the most. The electrode is an alloy with low melting point, which is melted quickly, The melted alloy electrode core adheres to the object to be welded, and after cooling, the object to be welded is bonded together
because inverter welding machine is a typical switching power supply (output characteristics have great characteristics), the output power is large, the working environment changes greatly, so the quality of components is required to be good, so as to ensure the stability of work and long life
driving board function the control board function principle is that the driving board function is to amplify the molated driving signal sent by the control board to drive the power switch device, and isolate the high voltage and large current on the main circuit switch device from the control board
the function of the control board is to collect the current and voltage signals at the output end of the welding machine according to the current and voltage parameters given by the panel, and then control the PWM pulse generation circuit to generate suitable driving pulses and send them to the drive board after comparison and calculation

inverter arc welding power source, also known as arc welding inverter, is a new type of welding power source. This power source converts the three-phase power frequency AC network voltage into DC through rectifier rectification and filtering, and then inverts it into several kHz ~ tens of kHz intermediate frequency AC voltage through the alternating switching action of high power switching electronic components, At the same time, the voltage is reced to several tens of V suitable for welding by transformer, and then rectified again, and the stable DC welding current is output by reactance filtering
