Safety standards for power supplies

This official ZVEI guideline can help choosing the right safety standards for power supplies.


Due to their potential for danger, power supplies are undoubtedly in the focus of safety approvals. Such devices must be safe both during normal operation and in the event of a fault.

This "best practice" guideline deals exclusively with the requirements for the basic safety of power supplies and should serve as a decision-making aid for the technical staff of the manufacturers and the professionally skilled users. It can be used to avoid wrong decisions, which are usually associated with high costs and loss of time, early.
