IEC AC Option IEC 61000-4 AC Immunity Test Routines Available Features: Includes Complete Test Sequences for the following IEC 61000-4 Conducted Immunity Test Standards: • IEC 61000-4-11, Voltage dips, short interruptions and voltage variations immunity tests for equipment with mains current less than 16 A per phase • IEC61000-4-13, Harmonics and inter harmonics including mains signaling at AC power port, low frequency immunity tests • IEC61000-4-14, Voltage fluctuation immunity test • IEC61000-4-27, Unbalance, immunity test for equipment with input current not exceeding 16 A per phase • IEC61000-4-28, Variation of power frequency, immunity test for equipment with input current not exceeding 16 A per phase • IEC61000-4-34, Voltage dips, short interruptions and voltage variations immunity tests for equipment Common Features for all IEC 61000-4 Test Sequences • Pre-set test sequences and test levels conform to IEC 61000-4 test standards, ready to test out of the box. No need for any programming by the end-user saves time. • Immunity tests can be run continuously or in single step mode to allow close observation of EUT performance. Enables detailed review of EUT behavior to help implement needed design changes. • AC measurements such as voltage and current are recorded at each test step and included in test reports. Documents and validates correct EUT behavior during and after test runs. • • • IEC Immunity Testing The EMC Directive is one of the 'New Approach' Directives and applies across all 27 member states of the European Union (EU). The Directive applies to all electronic or electrical products liable to cause or be disturbed by electromagnetic interference (EMI). As a result a large number of manufacturers in the electronics or electrical industries need to ensure that their products are compliant with the requirements of the Directive and be able to demonstrate that this is the case in order to affix the CE Mark. To verify compliance with these directives, the International Electrotechnical Commission (http://www.iec.ch) has issued a number of harmonized standards that describe test methods, test levels and pass or fail criteria. A number of these test standards cover immunity to commonly found AC line anomalies that are known to occur on the public Low Voltage (LV) network. These conducted immunity standards are numbered IEC 61000-4-nn. These IEC 61000-4 standards are not product specific but rather generic and may be applied to numerous product categories to ensure compliance with CE mark requirements. There are additional product specific IEC standards that cover individual product types. To determine the IEC 61000-4 tests that apply to a particular product category, refer to the relevant product standard. For example, the IEC EMC product standard that applies to programmable User guided prompts the operator through entire test procedure. No IEC Standards knowledge required AC power sources is IEC 61326-1, “Electrical equipment for measurement, on the part of the operator, less chance of mistakes. control and laboratory use – EMC requirements”.

IEC AC Option IEC 61000-4 AC Immunity Test Routines IEC 61000-4-11 Voltage Dips, Interruptions and Variations Voltage Dips and Interruptions immunity applies to virtually all electrical products that require the CE mark. This requires testing per IEC 61000-4-11 to determine the ability of the equipment under test to withstand such AC line anomalies. Actual test levels and durations depend on the product class. Products are categorized into four classes, 1, 2, 3 and X, with X being a class defined by individual product committees with the restriction that they cannot be less severe than class 2....

IEC 61000-4 AC Immunity Test Routines Voltage Rise and Fall Time Requirement IEC AC Option Parameter The requirement to meet a 1 to 5 msec rise and fall time of the AC voltage has been the cause of much confusion over the years as it necessitated the use of multi-tap transformers and electronic transfer switches to meet this requirement, adding excessive cost and economic burden to test labs and other end users of EMC compliance equipment. As the actual voltage dips and interruptions called out in product standards that reference the IEC 61000-4-11 standard are all performed at zero crossings...

IEC 61000-4 AC Immunity Test Routines IEC 61000-4-13 Harmonics and Inter Harmonics The objective of the IEC 61000-4-13 standard is to ensure that products are impervious to the effects of signaling frequencies that may be present on the public utility power grid. Signaling over AC power lines is often used to remotely control switch gear or other devices. The IEC 61000-4-13 test requirements are rather extensive compared to the other IEC 61000-4 tests. It also requires a second, asynchronous wave form generator capable of generating inter harmonics. Inter harmonics are not harmonically related...
