The data plate on the rear of the plasma power supply has two sets of ratings:
- The HYP ratings are Hypertherm® plasma power supply ratings. They show the capacity of the system related to internal testing done by Hypertherm.
- The IEC ratings are the minimum ratings that the system must get to meet the requirements of International Electrotechnical Commission (IEC) standard 60974-1.
CSA, CE, and CCC data plates can differ slightly.
