FAQ

• Q1: Which rectifier units are compatible with this control board?
  A: The CMIB-11C control board is compatible with ABB 3AUA series rectifier units; compatibility depends on the rated current of the unit.

• Q2: What happens if the output current exceeds the rated value?
  A: The board has overcurrent protection that automatically limits output current to prevent damage to the rectifier unit and load.

• Q3: Can it be used in high-humidity environments?
  A: Yes, it operates in relative humidity 5%~95%, but condensation must be avoided.

• Q4: Can the board be hot-swapped in case of failure?
  A: Hot-swapping is not recommended. Power should be off before replacement to avoid damage.

• Q5: Does the board have temperature protection?
  A: Yes, it will automatically cut output if the temperature exceeds the set limit to prevent overheating.

• Q6: Does the control board support remote monitoring?
  A: Yes, it can connect to monitoring systems to report current, voltage, and fault status.

• Q7: Is there a required orientation for installation?
  A: Yes, follow the marked orientation to ensure proper heat dissipation and electrical connection.

• Q8: Does voltage fluctuation affect the control board?
  A: The board has voltage regulation and filtering; minor fluctuations are tolerated, but sustained overvoltage may trigger protection.
