IEC EN 610004-16 is an international standard that specifies the power frequency voltage dip immunity requirements for electrical and electronic equipment meant to be operated in low-voltage power supply systems. It is a part of the Electromagnetic Compatibility (EMC) standards, which focus on ensuring the effective operation of equipment despite disturbances caused by electromagnetic phenomena.
Understanding Power Frequency Voltage Dips
Power frequency voltage dips can occur due to various reasons such as faults in the power grid or sudden changes in load demand. These dips may cause temporary drops in voltage levels, leading to disruptions or malfunctions in electrical and electronic equipment. IEC EN 610004-16 sets out the criteria for the acceptable dip depth, duration, and the number of dips that the equipment should withstand without losing functionality.
Application of IEC EN 610004-16
This standard is applicable to a wide range of equipment, including home appliances, industrial machinery, medical devices, and information technology equipment. Manufacturers need to ensure that their products meet the specified immunity criteria mentioned in IEC EN 610004-16 before they can be considered compliant and safe for use in different environments.
Evaluating Compliance with the Standard
To assess compliance with IEC EN 610004-16, equipment is subjected to tests where voltage dips at different depths and durations are applied. The equipment's performance during and after these tests is evaluated to determine its susceptibility to power frequency voltage dips. If the equipment continues to function as intended without any adverse effects, it is considered to be in compliance with the standard.
