We can't find the regulations for level of PFC required above 1kw? Is an electric car battery charger considered as professional equipment? Otherwise EN 61000-3-2 (iec 1000-3-2) class A harmonic current limits apply.
Hi guys, I'm in the middle of designing of an input filter for a power supply with an active PFC circuit. The power supply needs to comply with iec 61000-3-2 for conducted emissions. I'm reading through the standard, but I'm having difficulties finding anything on the high frequency parts. The maximum harmonic limited is the 40-th which at 60Hz
Hi i have very basic/fundamental question ! We design product for CE certification . That includes surge requierment (iec 61000-4-5). If we look at the standard it safecify pulse voltage , source resistor , timing at 25degC . The satndard also talks of some variation , too. It's easy to design for 500V/2 ohm surge with all this variation and
dear all We are trying to set up a calibration procedure for the measurement of transfer Impedance of ESD Target. For this we are following the iec 61000-4-2 edition 2 Standard. This procedure is based on the set up given in this standard. In the set up, a current source is given at the input side which gives the current to the target . Here I
It's said why - to handle iec 61000-4-5 surge level 2 (1 kV).
Hello forum, Can anyone explain or refer me a link listing iec standards based on electronic products.For an instance,iec 61000-EMC standards. I want to know what "61" indicates???Is it a separate family holding a particular field.(i.e, DAQ's,PLC etc..) I just want that particular information.Please,explain me about the standard (...)
Hi, This is not totally related to analog circuit design but there are no threads specifically for this topic. I wanted to ask when iec 61000-4-2 ESD test is performed on an equipment should the equipment be operational. Take for example a computer is tested then is it enough that the computer cord is connected to socket so as to provide ground
Look at this picture: 76833 A such ESD test can shot holes in gorilla glass, doubt any protection helps in this case. Testing for immunity to electrostatic discharge for cell phones are however done with "only" 8kV. A common standard: iec 61000-4-2 Anything that the user can touch is tested. Is there for example a USB re
A EMC standard compliant test would mainly refer to iec 61000-4-4 burst specification. But I don't see an easy way to reproduce it with DIY methods. The test involves a burst of high voltage pulses, of e.g. 1 kV magnitude, standard 5n/50 ns shape, repetition rate up to 1 MHz. For peripheral interfaces, the standard specifies capacitive coupling to
How to simualte ESD, EFT, SURGE ,according to iec-61000. Which software should I USE. THKS
Hi Waseem, Out of curiosity and for clarification, do you mean the "iec" 61000-4-2. It is a system level electrostatic discharge test for EMC compliance issues, tested using a zap gun, but was never meant for "ESD" testing. If you want to buy it, the iec spec, you can find it here:
Hi, have run into some problems. I need to design a power supply for 24V dc 1amp. The problem is that it needs to fulfill a lot of standards. The device that has the built in power supply needs to be classified for use on ships. I need to fulfill the following standards. iec 61000-4-4 Fast low energy trancient (burst) test iec (...)
Hi I want to understand iec 61000-4-2 to 4-5, for EMI / EMC testing. Can somebody provide some notes on the subject Thanks
My power supply failed while doing EFT (iec 61000-4-4) and SURGE (iec 61000-4-5) tests. I want to place a MOV across the LINE and NEUTRAL. Should it help? Have problem in varistor selection.
Hello! Didn't know which area is the best one for this... I hope it is not off-topic here: Does anyone have a drawing or an instruction on how to build a capacitive coupling clamp for compliance tests and for EMI tests? Tests according to iec 61000-4-4 and similar (surge and burst injection into data lines). I don't need a calibrated equip

To all, I am looking for the following standards: iec 61000-6-1 iec 61000-6-2 iec 61000-6-3 iec 61000-6-4 Is there anybody who can help me. Goliath
