Safe and easily to Overclock the 88T miner to 100T-110T under 31W/J Efficiency. 29.5 ± 5%. Power supply AC input voltage, Volt. Power supply AC Input Frequency Range, Hz. Power supply AC Input current, Amp. Miner Size LengthWidthHeight, w/o. Miner Size (LengthWidthHeight, with package), mm. Operation humidity(non-condensing), RH. (1-1)Caution: Wrong input voltage may probably cause miner damaged. (1-2)Max condition: temperature 40°C, altitude 0m. (1-3)Two AC input wires, 10A per wire. (3-1)When the miner is used at an altitude from 1000m to 2000m, the highest operating temperature decreases by 1? For every increase of 300m.
