The Antminer fixture voltage regulator board is used to skip the test fixture's detection of the PSU version when using the Antminer universal test fixture to detect the hash board fault. It is no longer necessary to use the original power supply. We directly use the WANPTEK KPS3030D DC PSU to power the hash board. The module is suitable for Antminer S21, T21, S21XP, KS5, KS5PRO, S19Hydro, S19XP Hydro, KA3, HS3, KS3, DR7, K7, D7, L7, S19kPro, S19XP, S19Pro, S19jPro, S19j, S19+, S19jPro+, T19, S19, S19i, S17+, S17e, S17, S17Pro, T17+, T17e, T17, etc. hash board repair.

Usage tutorial on Antminer tester voltage regulating board:

Comparison before and after using the tester voltage regulating board:

Before: The noise was high, and it was impossible to observe the voltage and current changes on the hash board in real-time.

After: The noise is small, and the voltage and current changes of the hash board can be observed in real-time.

Product advantages:

1) After using the KPS3030D power supply instead of the miner's original PSU, maintenance work will say goodbye to noise.

2) Using the KPS3030D power supply, you can see the current changes at any time during maintenance to prevent the hash board from burning out due to abnormal currents.

3) It is suited for most power supplies of Antminer miners, such as APW11A1216-1a, APW171215a, APW11, APW121215a, APW121215b, APW121215c, APW121215d, APW121215e, APW121215f, APW121215g, APW121417a, APW121417b, APW9, APW9++, etc.

After purchasing the voltage regulation board, we will give you an extra Antminer 4-pin 18cm voltage regulation cable to connect the test fixture and the voltage regulation board.

The connection method is as follows:

① and ② red and black alligator clip power cable: connect the positive and negative electrodes of the test fixture and the hash board respectively;

③ Test fixture cable: connected to the test fixture and hash board;

④ USB to TTL cable: connected to the tester and the computer;

⑤ 4pin voltage regulation cable: connected to the Antminer tester voltage regulating board and the fixture;

⑥ Test fixture data interface: connected to the Antminer tester voltage regulating board;

⑦ 12V powering interface: used to powering the fixture.
