What is en 61000 4?
IEC 61000-4-4 is the International Electrotechnical Commission’s immunity standard based on electrical fast transient (EFT) / burst transients.
What is an EFT test?
EFT testing is an immunity standard used to test how electrical and electronic equipment operate under interference. EFT testing involves several tests to check the compatibility of a device with fast transients such as power line transients and electrostatic discharge.
What is ESD immunity?
IEC 61000-4-2 is an international test standard that outlines electromagnetic immunity requirements for electronic equipment when exposed to electrostatic discharge (ESD) generated from a human body or metal objects.
What is ESD testing?
ESD testing is an electromagnetic compatibility test (EMC test). ESD testing simulates various electrostatic impacts that equipment might experience either during transit or operation. An electrostatic discharge test determines whether a product is in compliance with its ESD protective area and procedures.
What is EFT pulse?
Electrical Fast Transients, also going by fast transients or bursts (EFT/B) are a series of quick, high frequency pulses often caused by arcing. A common cause of power line transients occur when an AC/DC connection is made or broken, equipment powered down, or circuit breakers switched.
What is IEC ESD?
The IEC standard replicates a charged person discharging into a system in an uncontrolled environment. This test is performed to ensure the system will remain operational in an end user environment where no ESD stress precautions are taken.
How does an ESD gun work?
ESD pulses are fast, high-voltage pulses created when two objects with different electrical charges come into close proximity or contact. Recreating them in a test environment helps to verify that the device under test is immune to static electricity discharges.
What is the IEC 61131 3 standard protocol?
IEC 61131-3 is the international standard for programmable controller programming languages. As such, it specifies the syntax, semantics and display for the following suite of PLC programming languages: Ladder diagram (LD) Sequential Function Charts (SFC)
What is EMC and ESD testing?
ESD stands for electrostatic discharge. Every EMC compliant product has to be tested on ESD during its development. This means that EMC compliant products should withstand certain electrostatic discharges of e.g. 1kV, 15kV or more.
