About 1246


According to the official data of Jianan technology, Avalon a1246 inherits the classic universal hardware design of the previous generation products (a11 Series), and makes special optimization for the actual deployment environment of the mine: the power supply is integrated in the chassis, supports vertical or flat deployment, and can flexibly adapt to different shelves; The force calculation board is fixed with the box wall by the pull-out track, which is convenient for rapid maintenance or replacement of the force calculation board during mine operation and maintenance. In addition, the fan module is also equipped with a temperature sensor, which is directly connected with the main control chip and can adjust the fan speed in real time according to the temperature of the force calculation board.
Human computer interaction experience also ushered in a significant upgrade. Thanks to the greatly optimized original mine management system, Avalon a1246 can dynamically adapt to the changes of mine environment, ensure the stable operation of mining machines and reduce the impact on the site power grid. At the same time, the new web management background can monitor the status of mining machines at any time, support visual human-computer interaction, automatically remind of abnormal operation, actively shut down in case of sudden faults that seriously affect computing power, and reduce unnecessary power expenditure.
In terms of security, Avalon a1246 is equipped with new firmware, strengthens the original tamper proof mechanism, and has built-in AI chip k210 in the main control board of the machine. It analyzes the fluctuation of computing power through intelligent algorithm, adjusts the fan speed, identifies potential network attacks and vulnerabilities, stabilizes the computing power in a reliable range, and prevents the loss of computing power.
As the first model of Avalon A12 series, Avalon a1246 has a computing power of 90t, successfully ranking among the current high computing power models. In addition, Avalon a1246 also lowers the energy efficiency ratio to 38t / J, which is one of the few machines on the market with an energy efficiency ratio below 40J / T.


Comments on 1246 miners in Avalon, Canaan
Canaan avalonminer 1246 is the first 90th / s bitcoin miner produced by avalonminers. The maximum power consumption of the device is 3420w. One of the miners has high power consumption. Its power efficiency is 38j / th. It has an integrated reliability design.
This device integrates the power supply with the rack. Its maximum voltage is 285v and its frequency range is 50Hz to 60Hz. The AC current of this device is 16A. Canaan avalonminer 1246 provides great flexibility and is suitable for various cabinet sizes. Its dimensions are (331 mm x 195 mm x 292 mm). The shell is made of aluminum with a net weight of about 12.8 kg.
The device is equipped with four fans. These fans help the machine dissipate heat. Due to its high hash rate and high power consumption, the machine generates a lot of heat. Nevertheless, the presence of four fans helps to keep the machine at the best and effective temperature by dissipating the heat generated by the machine.
In order to improve the heat dissipation effect, a1246 equipment is equipped with high temperature resistant 12038 cooler main fan. There are two fans in front, which are used for air inlet. Each of them has seven blades, which further increases the pressure on the air contact area, deepens the air flow to penetrate the shell, and the internal dust is blown away. This special design helps to prevent dust from accumulating on the instrument panel, which may lead to electrostatic short circuit.
The design voltage of the fan is about 12V, and the DC is 4.5a. The double fans at the rear blow away the warm air inside to achieve better heat dissipation effect. These fans also protect maintenance workers from accidental blade contact with their surfaces.
Through the design of the software, it can dynamically adapt to the changes of the mine site, which is conducive to maintaining the safe operation stability of miners, minimizing the impact on the on-site grid and prolonging the designed mining life. There is also a new web management platform, which can monitor the situation of miners at any time. In addition, the automatic alarm on the device detects abnormal operation. If the machine has detected a fault that affects the hash rate of the device, the automatic alarm will shut down the device.
When the hash rate fluctuates, the built-in chip of the main control board analyzes the fluctuation of the hash rate through an intelligent algorithm. It can also adjust the fan to identify potential network attacks and vulnerabilities. However, it stabilizes the hash rate to avoid hash rate loss.

Energy consumption of Canaan avalonminer 1246
This miner consumes a lot of power, so the equipment needs enough power supply units to operate efficiently. The miner consumes 3420w power. For new miners considering purchasing the equipment, the power supply unit of the equipment needs to be considered. The cost of electricity also needs to be known because it is in different locations.


Barn show


We have our own barn in diferent part of China , we not just sell miner, but also we are in the mining activity. So no matter you are new or old in mining , we are able to give systematic recommendations from miner set up to barn construction.
