IEC 61000-4-5 Surge Immunity Testing
Radiometrics Midwest Corporation provides IEC 61000-4-5 surge immunity testing for electronic and electrical equipment at our A2LA-accredited EMC laboratory in Romeoville, Illinois.
IEC 61000-4-5 evaluates the immunity of equipment to high-energy electrical surges that may occur as a result of switching events and lightning-related disturbances.
Radiometrics performs surge immunity testing using the test levels, coupling methods, polarities, phase relationships, and performance criteria required by the applicable product standard or customer test specification.
What Does IEC 61000-4-5 Testing Evaluate?
IEC 61000-4-5 testing applies controlled surge pulses to applicable equipment connections while the equipment under test (EUT) is operating and being monitored.
Depending on the applicable requirements and equipment configuration, surge testing may be applied to AC or DC power connections and other applicable interconnection ports using the coupling method specified by the test standard.
During testing, the EUT is monitored for unintended operation, resets, loss of function, communication errors, component damage, or other performance changes that may affect its ability to meet the required performance criteria.
Radiometrics IEC 61000-4-5 Surge Testing Capabilities
Radiometrics performs IEC 61000-4-5 surge immunity testing on a wide range of electronic and electrical equipment. Test configurations are established according to the applicable standard, equipment power system, external connections, and intended operating conditions.
Our surge immunity testing capabilities include:
- Testing of applicable AC and DC power connections
- Testing of applicable interconnection ports
- Positive and negative polarity testing
- Coupling configurations required by the applicable standard
- Testing at surge levels specified by the applicable product standard or customer specification
- Operation and monitoring of the EUT during testing
- Evaluation of multiple operating modes when required
- Engineering assistance when surge susceptibility is observed
Planning an IEC 61000-4-5 Surge Test Program
The IEC 61000-4-5 test program depends on the applicable product standard, equipment power configuration, required surge levels, number and type of connections to be tested, operating modes, and equipment monitoring requirements.
For AC-powered equipment, the power configuration and applicable coupling conditions are particularly important when developing the test plan. Equipment with DC power inputs or additional external connections may require different test configurations.
Providing complete power and interface information before testing allows Radiometrics to determine the applicable test conditions and prepare a more accurate quotation.
Information Needed for an IEC 61000-4-5 Quote
To help Radiometrics develop an accurate surge immunity test program and quotation, please provide the following information when available:
- Applicable product standard or customer test specification
- Product description and model number
- AC or DC input voltage and current requirements
- Single-phase or three-phase power configuration, when applicable
- Number and type of external power and interconnection ports
- Required peripherals and support equipment
- Operating modes to be evaluated
- Required surge test levels, if known
- Method used to monitor equipment performance during testing
Surge Immunity Troubleshooting
If a product experiences a performance problem or component failure during surge testing, Radiometrics can work with your engineering team to help identify the affected circuit or interface and evaluate potential corrective measures.
Where practical, changes to transient protection, grounding, filtering, power-input circuitry, or other design elements can be evaluated during the test program to determine whether they improve surge immunity.
