Brand new original Bitmain APW12a 277V power supply for S19J Pro-A, S19 Pro-A SHA256 air-cooled miners.
There are many kinds of APW12 power supplies; please pay attention to the model and version when using them. The main models of the APW12 power supply are APW121215, APW121417, and APW12A. These types of power supplies are not compatible with each other. The main differences are as follows:
1. The APW121215 power supply is suitable for most models of the 19 series, and 1215 means the power supply's output voltage is 12-15V. It contains multiple versions of a b c d e f.
2. APW121417 means the power supply's output voltage is 14-17V. This power supply is currently used in L7 and some S19 miners. Currently, there are two versions, a and b, and version b is compatible with version a.
3. APW12A, this power supply is suitable for 277V input. Countries and regions that use 277V standard voltage, such as the United States, can purchase models of this power supply version, and the latest version is APW1215g.
Reminder: When replacing the power supply, pay attention to the model and version of the original power supply. Avoid replacement errors that render the miner unusable or cause burnout.
