Antminer L11 20 GH/s Scrypt mining hardware

Scrypt ASIC for LTC and DOGE mining

The Antminer L11 is an application-specific integrated circuit miner built for the Scrypt algorithm. It delivers a typical hashrate of 20 GH/s for mining Litecoin, Dogecoin and other compatible Scrypt currencies. The unit connects via RJ45 Ethernet 10/100M and operates on single-phase AC input between 220 and 277 volts. It is intended for operators who need dedicated Scrypt mining hardware with a fixed performance profile.

Thermals noise and power draw

The miner draws a typical 3680 W at the wall with a power efficiency of 184 J/GH. Four integrated fans provide air cooling and move up to 480 CFM, producing a noise level of 76 dBA at 25 °C ambient. The operating temperature range spans -20 to 45 °C and the unit is rated for altitudes up to 2000 m. Humidity tolerance is 10 to 90 percent non-condensing.

Upgrade from lower-output Scrypt miners

Replacing an older Scrypt ASIC that delivers significantly less than 20 GH/s or operates above 184 J/GH will reduce energy cost per gigahash and increase daily coin output. The efficiency gain is most valuable where electricity rates are high or where rack space and cooling capacity are limited. The jump is worthwhile when the higher hashrate and lower joules-per-gigahash improve the mining margin enough to offset the hardware investment within the planned operating window.
