Antminer Voltage Regulator Board – Universal Repair Tool for S21 T21, KS5 S19 Hydro S19XP & 30+ ASIC Miners

Antminer Voltage Regulator Board | Universal PSU-Bypass Test Tool for S21 / T21 / KS5 / S19 Hydro / S19XP and 30+ ASIC Miner Models

The Antminer Voltage Regulator Board is the PSU-bypass adapter that lets repair benches drive Antminer hashboards directly from a WANPTEK KPS3030D bench DC supply instead of the noisy production PSU. Bypasses Bitmain's PSU version detection — the bench supply doesn't need to spoof a specific APW firmware version, the board takes care of that handshake. Eliminates loud miner PSUs from the bench, exposes real-time current draw, and accelerates hashboard fault triage.

Covers 30+ Antminer models across air-cooled, hydro and immersion variants — from the latest S21, T21, S21XP, S19 Hydro, S19XP Hydro, KS5 / KS5 Pro through the flagship S19k Pro, S19XP, S19 Pro, S19j Pro+, KA3, HS3, DR7 and the legacy S17+, T17, L7, D7, K7. PSU compatibility includes APW9++, APW11A1216-1a, APW17 1215a, APW12 1215a-g, APW12 1417a/b. Includes a 4-pin × 30cm voltage cable and an 18-pin × 30cm data cable for plug-and-play integration with the test fixture.

When to Use the Voltage Regulator Board

• Hashboard fault diagnostic on a quiet bench — skip the noisy production PSU, run the board straight off the KPS3030D.
• Real-time current monitoring during chip-chain scan — spot the offending region as soon as the current spikes, before further chips burn.
• Repair shop standardisation — one tester covers the whole Antminer + KS lineup, no per-model PSU stack on the bench.
• Avoid wear on production PSUs — bench testing with a regulated supply doesn't waste APW17 hours on diagnostic duty.
• Multi-model farm operators — single bench tool replaces the rack of PSUs the bench would otherwise need.

Antminer Voltage Regulator Board Specifications

FAQ — Antminer Voltage Regulator Board

Q: Do I need the WANPTEK KPS3030D specifically?
A: The KPS3030D is the recommended bench PSU — it provides the voltage range and current capacity to drive Antminer hashboards safely. Other adjustable bench PSUs with equivalent specs (≥30V, ≥30A) can substitute, but the KPS3030D is the validated pairing.

Q: Does this tool replace the universal test fixture itself?
A: No — this board sits between the bench PSU and the test fixture / hashboard. The hashboard test fixture is still required for chip-chain scanning. The regulator board's role is to handle the PSU spoofing so the bench PSU doesn't need to.

Q: How do I pick the right interface (113 / 117 / 120 / 65) for my miner?
A: Interface number maps to the Antminer model family. The full interface guide ships with the board; email contact@lys-sz.com with your miner model if you need to confirm before ordering.

Q: Bulk pricing for repair shops outfitting multiple benches?
A: Yes — email contact@lys-sz.com with your bench count and we'll send bench-kit pricing including the regulator board, cables and matching KPS3030D bench PSU.
