ERR_VOLT_RANGE Warning

Antminer – PSU Voltage Out of Range

voltage out of range

Warning — Should be addressed soon

Affected Models: All Antminer models with APW PSU

Symptoms

  • Hashrate fluctuates
  • Miner may periodically restart
  • Voltage readings in dashboard are unstable

Step-by-Step Fix

1

Measure PSU output voltage with a multimeter — should be 12.0-12.5V DC.

2

Check input wall voltage — should be stable at 110V or 220V depending on PSU model.

3

If running on 110V, verify the circuit is providing at least 15A. Low voltage under load is common on weak circuits.

4

Check all power cable connections for corrosion or loose fit.

5

If voltage is consistently wrong, replace the PSU.
