There are many kinds of APW12 power supply, please pay attention to the model and version when using.
At present, the main APW12 power supply models are: APW121215, APW121417 and APW12A. These types of power supplies are not interchangeable with each other, and the main differences are as follows.
1. APW121215, this power supply is widely used at present. Most of the 19 series models use this power supply. The 4-digit number 1215 after APW12 represents the output voltage of the power supply is 12-15V. At present, there are many versions of this power supply, there are a b c d e f. The generality is as follows:
a. APW121215 a /b /c versions are interoperable (no voltage feedback).
b. APW121215 d /e /f versions can be used with each other (with voltage feedback).
c. APW121215 d /e /f version can replace part of a /b /c use by upgrading firmware, but a /b /c version cannot replace d /e /f use.
2. APW121417, the last 4 digits of this APW12 power supply are 1417, which means the output voltage of the power supply is 14-17V. This power supply is currently used in L7 and some S19 mining machines. There are also two versions a and b, and the b version is compatible with the a version, but the a version is not compatible with the b version.
3. APW12A, this power supply is suitable for 277V input. The United States and other countries and regions that use the 277V standard voltage can purchase models with this version of the power supply. The latest version is APW1215g.
*Note: When replacing the power supply, be sure to pay attention to the original power supply model and version. Avoid replacement errors, which will make the miner unusable or cause burnout.
