Preface
Lightning surge is a high‑frequency item in EMC (Electromagnetic Compatibility) testing. Transient high‑energy pulses generated by grid switching and indirect lightning strikes may cause equipment malfunction or permanent damage.
IEC 61000‑4‑5 / GB/T 17626.5 are fundamental standards for surge immunity, which are mandatory references for CE and CCC certifications. This article introduces the domestic SUG‑562 surge generator, covering its functions, key parameters and selection considerations.
Note: This article sorts out technical information for R&D and test‑bench reference.
1. Applicable Standards & Test Capabilities
The SUG‑562 surge generator simulates surge pulse interference and supports pre‑compliance testing for single‑phase equipment for CE and CCC certification.
Complied Standards:
• IEC 61000‑4‑5
• EN 61000‑4‑5
• GB/T 17626.5
• Power‑port test: Completed by the built‑in coupling‑decoupling network.
• Communication‑line surge test: Expandable with an external coupling network.
2. Hardware Features

Summary
When building an EMC test bench, priority evaluation items for surge generators include standard compliance, DUT power capacity, waveform quality, on‑site calibration feasibility and automation interfaces. Domestic test instruments can satisfy most pre‑compliance test requirements for domestic certifications.
Tip: Model selection shall be based on the actual test standards and voltage/current ratings of the DUT.
