Antminer S15 28Th adopts hash algorithm (SHA-256) and is equipped with 7nm ASIC chip BM1391AE. There are four built-in hashboards, each with 72 BM1391AE chips, a total of 288. At launch, the miner was rated as “long-term mining, energy efficiency,” emphasizing high performance, durability, and energy efficiency along with less power consumption.There are two mining modes: high performance and energy saving mode.
Antminer S15 adopts a similar fan structure to the S9, with a single-sided air intake and an integrated power supply. The all-in-one design reduces wiring for a simpler look and more operation and maintenance. The miner has its own voltage regulation line on the control board, which can be switched between energy-saving and high-temperature modes. Compared with the previous series, the control board area of Antminer S15 is further reduced to 115mm * 95mm.
Bitmain antminer T15 hash board repair parts, antminer t15 hash board replacement parts repair kit. During the long-term continuous operation of the hash board, some components are prone to failure. For example, Bitmain Antminer BM1391AE, T451 temperature sensor, MP1517DR, AT24C02D 02DM, capacitor 330 30V, SMD 50V 47UF electrolytic capacitor, etc. They are some vulnerable electronic components on the T15 hash board, and a low hash rate on a single chip will also result in a low or no hash rate for the entire hash board. Therefore, after the summary of professional repair personnel, to achieve fast and accurate maintenance, professional t15 hash board maintenance kits can be used.
