Antminer APW8 - III. The Principle and Structure of the Power Supply; 1. Principle overview; 1.1 APW8 consists of 1 large panel, 2 fans and the upper and lower enclosures. The normal input AC220 V has two DC output voltages, which are SB 12 V respectively. The main voltage; 1.2 Performance characteristics and scope of use: S15, T15 with APW8 power supply 16.32 V-20.04 V as follows:

output is controlled by the PIC port and the mining machine communication, and
different models’ DC voltage range is (8V-9.2V, 10V-11V, 16.32V-20.04V)
1.2 Performance characteristics and scope of use: S15, T15 with APW8 power supply 16.32V-
20.04V as follows:
APW8 power supply is a high-efficiency DC power supply designed and manufactured by our
company. It has single-phase AC input and two DC outputs:
1>. 16.32V-20.04V voltage adjustable output, the maximum current can reach 95A;
2>. 12V voltage fixed output, the current can reach 5A.
The adjustable output part of voltage can meet the common DC load use within 95A current of
the adjustable voltage range, especially suitable for circumstances with strict requirements for
power supply of servers and mining machines; the 12V voltage’s fixed output part can meet
the use of control panel and cooling fin.
1.21 The are following characteristics:
 200-240V voltage input
 There is protection for undervoltage, short circuit, overload, over temperature, with
automatic recovery after fault removal
 The use of high-quality devices ensures stable and reliable products through reasonable
design, and can work at full load for a long time in a high temperature environment at 60°C
or lower.
 Small size, high power density
