How to use the Antminer test fixture voltage regulator board repair tool?

When using the Antminer fixture voltage regulator board and the Antminer universal test fixture to detect the fault of the hash board, by skipping the detection of the PSU version by the test fixture, the voltage-regulated PSU can be used to power to the hash board instead of the miner PSU, so there is no need to use the original PSU. During the test, directly use the WANPTEK KPS3030D DC PSU to power to the hash board. Among them, the Antminer 4-pin 18cm voltage regulating cable is used to connect the test fixture and the voltage regulator board.

The test fixture voltage regulator board is suitable for Antminer KS5, KS5PRO, KA3, HS3, KS3, DR7, K7, D7, L7, S21, T21, S19 series, etc. This product is applicable to many models of miner hash boards and power supply versions.

How to connect the voltage regulator board?

One of 4 pin port for the voltage regulating cable is connected to the port of the voltage regulator board, that is, 1 is connected to 3 (One of the four interfaces can be determined and selected according to the hash board model.); the other end interface of the voltage regulating cable and the cable interface on the voltage regulator board are connected to the test fixture, that is, 2 and 4 are connected to the tester.

Description of the voltage stabilizer board interface:

The above figure shows the 4 interfaces of the voltage regulator board. The following content is the PSU models corresponding to the 4 interfaces. If a certain power supply version is needed when testing the hash board, connect the voltage regulating cable to the corresponding interface number.

Interface ①: The corresponding power supply models are APW121215a, APW121215b, APW121215c, APW121215d, APW121215f, APW121215g, and the applicable miners are S19, S19j, S19j+, S19Pro, S19jPro, S19jPro+, S19XP, S19KPro, S19aPro, S19a, S19Pro-A, S19i, T19, D7, E9, E11, E9Pro, etc.;

Interface ②: The corresponding PSU model is APW121215e power supply, and the applicable miners are S19Pro, S19jPro, S19XP, S19L, etc.;

Interface ③: The corresponding PSU models are APW171215a, APW121417a, APW121417b, and the applicable miners are S21, S21XP, S19jXP, KS5, KS5PRO, S19, S19XP, L7, S19JL, K7, L7, DR7, KA3, KS3, HS3, etc.;

Interface ④: The corresponding power supply models are APW11A1216-1a, APW11, APW9, APW9++, and the applicable miners are T21, S19Hydro, S19XP Hydro, S17 Pro, T17, S17, S17, S17e, S17+, T17e, T17+, etc.

Installing the Antminer test fixture voltage regulator board helps us directly detect the hash board without the need to detect the power supply version.
