What is BS EN 61000-4-29 – Immunity test on d.c. input power port voltage dips, interruptions, and variations about?
BS EN 61000-4-29 is the fourth part of a multi-series standard used for Electromagnetic compatibility (EMC).
BS EN 61000-4-29 defines test methods for immunity to voltage dips, short interruptions and voltage variations at the d.c. input power port of electrical or electronic equipment. BS EN 61000-4-29 is applicable to low voltage d.c. power ports of equipment supplied by external d.c. networks.
Note: The test described hereinafter applies to electrical and electronic equipment and systems. BS EN 61000-4-29 also applies to modules or subsystems whenever the EUT (equipment under test) rated power is greater than the test generator capacity specified in clause 6.
Note 1: The ripple at the d.c. input power port is not included in the scope of this part of IEC 61000. It is covered by IEC 61000-4-17,
Note 2: BS EN 61000-4-29 does not specify the tests to be applied to particular apparatus or systems. Its main aim is to give a general basic reference to IEC product committees. These product committees (or users and manufacturers of equipment) remain responsible for the appropriate choice of the tests and the severity level to be applied to their equipment.
Who is BS EN 61000-4-29 - Immunity test on d.c. input power port voltage dips, interruptions, and variations for?
BS EN 61000-4-29 on Electromagnetic compatibility (EMC) is useful for:
- Manufacturer of electronic equipment
- Manufacturer of automotive parts
- Electronic engineer
Why should you use BS EN 61000-4-29 - Immunity test on d.c. input power port voltage dips, interruptions, and variations?
Electromagnetic compatibility (EMC) means that a device is compatible with its electromagnetic (EM) environment. This electromagnetic compatibility does not emit levels of EM energy that cause electromagnetic interference (EMI) in other devices in the vicinity.
BS EN 61000-4-29 specifies the test levels of voltage dips, short interruptions and voltage variations according to their operational requirements. A test generator is useful in preventing the emission of disturbances that may influence the test results. This also helps in determining the characteristics of the test generator. Test setup helps in performing the test by using the shortest power supply cable. Test procedure is specified for conducting the test in an appropriate manner. With the help of these test methods, you can ensure sustainability and immunity of these voltage dips, short interruptions and voltage variations.
By applying BS EN 61000-4-29, you can establish the common and reproducible basis for testing electrical and electronic equipment of these voltage dips, short interruptions or voltage variations on d.c. and input power ports. This helps in evaluating the performance and helps in determining the immunity that results in manufacturing good quality electronic equipment.
