The Bitmain Antminer APW12 1215a PSU is designed specifically for cryptocurrency mining. Its input voltage is 200 to 240V, the output voltage is 12 to 15V, and its net weight is 3.6 kg. APW12 12V-15V EMC a version is suitable for Antminer S19, S19j, S19 Pro, S19j Pro, S19a Pro, S19a, S19i, T19, D7, E9 and other air-cooled miners. The power supply has built-in protection functions such as undervoltage, output short circuit, overload, and overtemperature. It can operate stably for a long time in the environment of -20 to 45℃. 

Taking the S19j Pro miner as an example, if miner fails to start or suddenly loses power, the fan stops working, etc., it may be caused by the APW12 1215a power supply failure. At this time, the backup power supply should be used immediately to replace it so that the miner can resume normal operation.
