ASIC K3L Antminer Crypto Miner Tester – Multifunctional Hash Board, PSU & Fan Diagnostic Tool

K3L Antminer Multifunctional Tester | Hashboard, ASIC Chip, EEPROM, PSU and Cooling Fan Diagnostic Tool for ASIC Repair Shops and Mining Farm Operators

The K3L Antminer Multifunctional Tester is the all-in-one diagnostic device built for ASIC repair shops, mining technicians and farm operators. Replaces a bench rack of separate tools with one unit that handles hashboard testing, ASIC chip diagnostics, EEPROM editing, power supply testing and cooling fan verification — the four most common repair-bench workflows on a single device.

Built around a wider compatibility envelope than the earlier K8 and K9 testers, the K3L covers air-cooled and hydro-cooled Antminer generations from the S9 family up through the latest S21 / T21 / KS5, with built-in support for Bitmain APW8, APW9, APW9+, APW11, APW12 and APW17 power supplies. New for 2025: cooling fan testing function with support for both KF2510 (4-pin / 6-pin) and 5557 4-pin connectors — covers the connector variants used across the Antminer + Iceriver lineup. Faster scan speed than the K8 and K9 predecessors.

What the K3L Tester Covers

• Hash board testing — advanced diagnostics for the full Antminer model range, identifies failing chip positions along the chain.
• ASIC chip testing — full chip-level pass/fail validation on individual desoldered chips.
• EEPROM editing — read and import files to speed up firmware-level repair workflows.
• Cooling fan testing (new 2025 function) — KF2510 (4/6-pin) and 5557 4-pin connector support.
• PSU testing — Bitmain APW8, APW9 / APW9+, APW11, APW12, APW17 covered.

FAQ — K3L Tester

Q: Is the K3L a full replacement for the older K8 / K9 testers?
A: Yes — covers everything the K8 and K9 did, plus the new 2025 cooling fan testing function and wider PSU coverage. Scan speed is also faster. New bench positions should standardise on the K3L; existing K8 / K9 setups can be upgraded or run in parallel.

Q: Does the K3L work on Whatsminer or Iceriver hardware?
A: The K3L's primary lineup is Antminer + Bitmain PSU coverage. Test cables for Antminer and Iceriver are included; Whatsminer hashboards typically need their own dedicated test fixture (see related products).

Q: Does the kit include the bench power supply?
A: No — the K3L is compatible with 12V high-power adapters but the adapter itself is sourced separately. Pair with a WANPTEK KPS3030D bench PSU for the standard repair-bench setup.

Q: Bulk pricing for equipping multiple benches?
A: Yes — email contact@lys-sz.com with your bench count and we'll send bench-kit pricing including the K3L, recommended power adapter and matching test cables.
