Need help defining the test?

MSASPL provides surge immunity testing to evaluate product behaviour against high-energy voltage transients. Surge events may occur due to power switching, grid disturbances, lightning-related effects or inductive load changes.

Surge testing is important for AC-powered products, DC-powered devices and applicable signal interfaces depending on product configuration and test requirement.

Why Surge Testing is Important ?

Surge events can damage power input circuits, communication ports, protection devices, isolation barriers and sensitive electronic components.

Frequently Asked Questions

What is surge immunity testing?

Surge testing evaluates how a product withstands high-energy transient overvoltages that can be associated with switching events, power-system disturbances or indirect lightning effects.

Which standard is commonly used for surge immunity testing?

IEC 61000-4-5 is the commonly referenced basic immunity standard for surge testing. The required level and coupling mode depend on the product standard, installation environment and port being tested.

Which ports are typically considered for surge testing?

Power input ports are commonly evaluated, and other ports may also require surge testing depending on the applicable standard and cable configuration. The exact setup is confirmed before execution.

What product issues can surge testing reveal?

Possible symptoms include resets, fuse operation, protection-device damage, power-supply failure, communication interruption or permanent component damage.

Can MSASPL help identify likely causes of a surge failure?

Yes. Debug discussion can cover surge protection devices, fuse and MOV/TVS selection, input filtering, creepage/clearance considerations, grounding paths, power-supply protection and PCB current paths. Final corrective design decisions remain with the product engineering team.
