Antminer s4 bitcoin miner
The rest of batch 2 S4s will come with the improved power supply as standard. The following actions are being taken for miners already delivered: We are sorry for the inconvenience you may have experienced regarding power supply failures, or even sporadic events of smoke from our first batch of Antminer S4s.
We immediately set out to investigate the reports of failed power supplies from customers, and have made immediate changes to improve the quality of future deliveries. What happened with these power supplies is not acceptable. After investigations, it was found that the unusual service conditions a miner puts on its power supply was the cause of the failure.
The replacement power supplies have significantly upgraded PFC circuits in order to improve performance and prevent a recurrence of the problem. All internal components of the PSU meet the requirements of the ULV0 flame retardancy standard, which certifies that any ignition will self-extinguish within a maximum of 10 seconds.
In response to this problem, the sample filter in the Synchronous rectifier circuits have been altered to erase the excessive current, and so the MOSFET will not fail again.
In addition, several high temperature prevention circuits have been added which will better protect the power supply from overloading and excessive temperatures. We always perform significant dynamic testing on chosen power supplies, however in this case we failed to recognize the special conditions and specific loading characteristics the miner would place on the power supply. Our testing has been altered to replicate and include these loading characteristics on any power supplies introduced in the future.
The only thing you need is a power cord, which is not standard, but even if it were available, you probably would not get a cable with a suitable plug. Inside the case there are 4 processor boards installed in two rows one on top of the others.
Each board carries on itself 40 chips BM, made on 28nm technical process. They are installed in such a way that for every 8 chips there is one radiator. In addition to the distributed radiator system, the device is equipped with four coolers, two on the front and back covers of the casing. In addition to the work boards, the network controller and the LED indicator are mounted in the case. To connect to the network, a standard Ethernet interface is used. As for the indicator, it displays the name of the device itself, the working IP address, the current hashing speed, and its temperature.
