New Whatsminer M53 230T 232T 234T SHA-256 Algorythm Asic Miner

Specifications： Hashrate 226-250T±10% Power Ratio 29J/T±5% Power On Wall 6554~7250W ± 10% PSU AC380-480V, 3W+ ground, input 10kw Size 86mm*482.6mm*663mm with handle Net weight 27.5kg Weight with packaging materials 30kg Coolant demand per machine About 1L Power Cable Model Custom made , ≥16A Internet Connections Ethernet Environmental Parameters Liquid temperature ① Working temperature (inlet): 20℃ ~50@normal mode 20℃~40℃@high performance mode; ② Inlet temperature control accuracy ± 2℃ ③Storage and transportation temperature: -40~70℃   Note: please empty the liquid in the equipment during storage and transportation. Liquid flow ①Limited Data：≥10L/min ②Flow control accuracy ± 10%   Remarks: 10L/min corresponds to the temperature difference between inlet and outlet water close to 10℃@normal mode, 14℃ @high performance Mode Liquid pressure ≤350kpa   Remarks: when the pressure is more than 350kpa, the water-cooled plate will be deformed and cause the risk of coolant leakage. Liquid medium circulation First-level deionized water: meet the requirements of the national standard GB/T 6682-2008 first-level deionized water   Notice: 1)If the water conductivity is ≥100us/cm, the medium must be replaced; 2)The water conductivity is less than 5us/cm when the system is running for the first time. Liquid PH Control range: 6~8 Liquid medium circulation        system(Machine side) ①Anti-rust and anti-corrosion of pipeline;                ②The particle diameter of the liquid medium is ≤53 microns, that is, the circulation system is equipped with a 270 mesh filter;                                          ③Before connecting the cabinet to the heat dissipation system, clean and filter the system pipeline with deionized water to remove dust, welding slag and other impurities; ④The temperature resistance of system components is above 85℃; ⑤The circulatory system is recommended to be equipped with a UV lamp sterilization device to prevent the liquid from breeding bacteria and attenuate the heat dissipation capacity of the system; ⑥The system is equipped with a 4bar safety relief valve; ⑦The system is equipped with a constant pressure expansion tank.   Note: when the temperature of the coolant rises after the miner is turned on the pressure will rise. Humidity ①Working humidity: 5%RH~85%RH (non-condensing) ②Storage humidity: 5%RH~95%RH (non-condensing) ③Long-term storage humidity: 30%RH~69%RH (no condensation)   Remarks: The above liquid temperature and flow parameters are based on deionized water as the liquid medium. If the liquid medium uses antifreeze, the liquid temperature and flow parameters need to be calculated separately. Table 2 shows an example of 30% glycol antifreeze temperature and flow parameters. ▲Table2 Example of temperature and flow parameters of 30% ethylene glycol antifreeze Temperature ①Working temperature (inlet): 15℃~45℃@normal mode 15℃~35℃@high performance mode ②Inlet temperature control accuracy ± 2℃ ③Storage and transportation temperature: -40~70℃   Note: please empty the liquid in the equipment during storage and transportation Flow ①Limited Data：≥11L/min ②Flow control accuracy± 10%   Remarks: The temperature difference between the inlet and outlet liquids at this flow rate is close to 10℃ @normal mode, 14℃@high-performance Mode Warranty Period One year after leaving the factory
