About this miner

The Canaan AvalonMiner 1246 is the first Bitcoin miner that has a 90Th/s produced by the company AvalonMiners. The device comes with a maximum power consumption of 3420W. One of the miners that have a high power consumption. It has a power efficiency of 38J/TH. It has an integrated design for reliability.

This device integrates the power supply with the enclosure. It has a maximum voltage of 285V and comes with a frequency ranging from 50Hz to 60Hz. The alternating current of the device is at 16A. The Canaan AvalonMiner 1246 provides great flexibility and fits various cabinet sizes. It has a dimension of (331 mm X 195 mm X 292mm). The enclosure, which is made of aluminum, has a net weight of about 12.8Kg.

The device comes with four fans. These fans help in the dissipation of heat from the machine. The machine produces a lot of heat due to its high hash rate and its high power consumption. Still, the four fans' presence helps to keep the machine at a temperature where it is optimal and efficient by dissipating the heat produced from the machine.

To improve the heat dissipation, the A1246 device is highly equipped with a high temperature resistant 12038 cooler master fans. The front has dual fans, and these fans are for air inlet. They have seven blades each, which further increases the air contact area pressure, deepening airflow penetration to the enclosure while the interior dust is blowing away. This particular design helps prevent dust accumulation on the dashboard, which can cause a short circuit due to static electricity.

The fan is designed with a voltage of about 12V and a direct current of 4.5A. The dual fans located in the rear area pushes away warm interior air to achieve better heat dissipation. These fans can also protect maintenance workers from blade injuries caused by accidental contact with its surface.

It is designed in terms of software to dynamically accommodate changes done in the mining sites, which help keep the operational stability of miners safe, minimize the impact on the site grid, and extend the mining life of the design. There is also a new web management platform that can monitor miner’s conditions at any point. In addition to all of these, the Auto alert on the devices detects operating anomalies. If the machine has been detected to malfunction, and it affects the hash rate of the device, the auto alert will shut down the device.

In the case where there is a fluctuating hash rate, a built-in chip in the main control board to analyze the fluctuations in the hash rate through intelligent algorithms. It also adjusts the fan and identifies potential network attacks and loopholes. It, however, stabilizes the hash rate to avoid hash rate loss.
