Notes
(1) The hashrate value, power on wall, and power efficiency on wall are all typical values. The actual hashrate value fluctuates by ±3%, and the actual power on wall and power efficiency on wall fluctuate by ±5%.
(2) Caution: Wrong input voltage may cause server damaged.
(3) The noise is loudest when the fan is under maximum RPM(rotation per minute).
(4) When the server is used at an altitude from 900m to 2000m, the highest operating temperature decreases by 1℃ for every increase of 300m.

SEALMINER A2 Description
Designed for mining BTC, the SEALMINER A2 breaks new ground in performance and efficiency with an advanced hash rate of 226TH/s. The miner expands the boundaries of mining capacity with its compact and lightweight design weighing only 20.5 kg. This makes the transportation and maintenance of SEALMINER A2 relatively simple.
The SEALMINER A2 is designed to excel in extreme conditions. The air-cooling model will thrive in temperatures between -20°C and 50°C. It features a custom fan and flow field design, lowering noise by 3-4 dB, and making it a virtually silent option regarding noise. This BTC miner is a wonderful home setup option. Beware that network connectivity is also important to ensure a successful crypto-mining experience. Proper network connectivity ensures pool communication, transaction validation, and data transfer between the miner and the existing network. You can opt for a triple-speed ethernet if you intend for large-scale operation. -
