- The power supplies widely used by Bitmain miners are APW3+ PSU, APW9+ PSU, and APW12 series PSU. These power supplies are an essential part of the normal operation of Bitmains mining machines, and once a failure occurs, it will cause the mining machine to stop, resulting in losses. The Bitmain APW3+, APW9+ and APW12 power supply repair training courses presented by ZMRC will properly teach you to repair a faulty PSU quickly and without error. These courses mainly include explaining several main circuit components of the power supply, such as EMI filter circuit, auxiliary power circuit, etc. Attention: the power supply has high voltage (300V or 450V), and it must be operated correctly during repair process, otherwise it is easy to cause damage.
