Conducted Transient testing aims to ensure that a given product can withstand short-duration electrical disturbances on power and signal lines. This testing evaluates the immunity of electronic and electrical equipment against fast voltage and current transients that may occur in real-world environments, helping prevent malfunctions, performance degradation, or permanent damage.
Transient events on AC/DC power lines and communication ports can cause resets, component damage, or system instability. Transient testing exposes these vulnerabilities early, reducing costly redesigns.
Transient testing puts stress on MOVs, TVS diodes, filters, SMPS controllers, and power stages to confirm that the protection and conditioning circuits behave correctly under high-energy and fast-edged disturbances.
Transient disturbances often trigger microcontroller brownouts, logic faults, timing errors, and communication dropouts. Transient testing verifies that your embedded systems remain stable and functional under IEC/EN 61000-4 transient conditions.
Conducted transient testing significantly increases MTBF and reduces warranty returns by validating robustness before your product reaches customers.
Conducted transient tests being done in an ISO/IEC 17025 accredited Lab, provide the proof of immunity performance required for CE Marking and international regulatory approvals.
The objective is to test immunity to repetitive fast voltage transients typically caused by switching of inductive loads, relay contact bounce, or other high-speed switching events on power or signal lines. Our test setup is equipped with cutting-edge single-phase and three-phase coupling/decoupling networks (CDNs) with a current rating of 32 A and transient generators capable of generating EFT pulses characterized by peak values up to 7-kV and durations down to nanoseconds with high repetition rates.
This aims to evaluates the equipment’s ability to withstand high-energy transients, such as those caused by lightning strikes, switching of the power grid, or large inductive loads. Surges are applied in the form of 1.2/50 µs voltage waves and 10/700 µs current waves applicable on AC mains, DC supply lines, and signal interfaces.
