KD BOX II authenticated modes
Default: 5 TH/s +/-5%, 400 W +/-5%, rated 80 J/TH. Low: 3.5 TH/s +/-5%, 260 W +/-5%, rated 74 J/TH. These are discrete manufacturer modes, not endpoints of a continuous range. The default mode is the directory comparison operand.
Electrical and cooling boundary
The miner accepts 12 V DC and requires an external PSU. Facility AC voltage, current, connector and protection come from the exact selected PSU and must not be inferred from the miner input. The manufacturer listing says “Power Cable 10A”; that is a cable label, not a measured equipment current or universal breaker size. Airflow is fan-cooled at a listed 4500 rpm.
Physical and environmental facts
Machine dimensions are 150 x 198 x 97 mm and net weight is 2.2 kg. Package dimensions are 300 x 220 x 142 mm and gross weight is 2.7 kg. The manufacturer rates noise at no more than 35 dB and humidity at no more than 65% RH. Its table says 0-35 C while safety prose recommends 10-35 C; use the conservative 10-35 C planning range and preserve the source conflict.
Firmware identity
The exact official artifact is firmware-Goldshell-KDBoxII-2.2.7.cpb. Match the exact model and controller, verify the file, and do not interrupt power. KD-BOX and KD2 images are not substitutes.
