The IEC 62477-2 standard, titled "Safety requirements for power electronic converter systems and equipment – Part 2: Power electronic converters from 1 000 V AC or 1 500 V DC up to 36 kV AC or 54 kV DC," is a critical group safety publication established by the International Electrotechnical Commission (IEC). It provides the fundamental safety framework for high-voltage power electronic converter systems (PECS) used in industrial and utility applications. Scope and Application
Test House Coordination: When sending equipment to a certified lab (like UL, TUV, or Intertek), they will test your device specifically against the clauses listed in this document. Comparison: IEC 62477-2 vs. IEC 61800-5-1
The IEC 62477-2 PDF specifies mandatory markings:
False. This standard is for industrial power electronic converter systems. Consumer wall warts fall under different standards (e.g., IEC 62368-1).
In the PDF, you will see that Part 2 refers back to Part 1 for basic rules (e.g., creepage/clearance, temperature limits) and then states: “This part supplements or replaces certain clauses of Part 1 for traction converters.”
IEC 62477-2:2018 is the primary international standard for the safety of high-voltage power electronic converter systems (PECS). It specifically covers equipment with rated voltages from 1,000 V AC / 1,500 V DC up to 36 kV AC / 54 kV DC.
