IEC61000-4-4 EFT Generator with 5KV Output 3-Phase CDN and PLC Touch Screen Control
The EFT-5K series electrical fast transient generators are precision instruments engineered for electromagnetic compatibility (EMC) compliance testing according to the IEC61000-4-4 standard. These robust testers deliver fast transient burst pulses up to 5KV, supporting repetition frequencies from 0.1 to 1200kHz, making them suitable for evaluating the immunity of industrial control systems, household appliances, medical equipment, automotive electronics, and components.
The integrated 3-phase 5-wire coupling and decoupling network (CDN) with 16A or 30A capacity ensures accurate simulation of real-world electrical disturbances in three-phase power systems.

The imported high-power non-inductive resistors ensure stable pulse waveforms with no deformation, delivering accurate test signals that meet IEC61000-4-4 requirements. This precision matters because distorted waveforms can lead to false test results, causing either unnecessary product redesigns or missed compliance issues.
The 7-inch LCD touch screen interface provides intuitive control with real-time parameter display. Operators can store up to 1000 test configurations, enabling quick recall for repeated test scenarios. The built-in temperature-humidity sensor monitors environmental conditions during testing.
The integrated 3-phase 5-wire coupling and decoupling network eliminates the need for external coupling equipment. With freely selectable coupling modes (L1, L2, L3, N, PE), the system adapts to various test configurations without additional hardware modifications.
The EFT-5K series serves quality assurance laboratories and EMC testing facilities evaluating electronic equipment for regulatory compliance. Typical use cases include:
- Pre-compliance testing for industrial automation controllers
- Household appliance certification testing for energy management systems
- Medical device validation for patient monitoring equipment
- Automotive component immunity assessment for engine control modules
The generator combines advanced pulse technology with intelligent control systems to deliver reliable, repeatable test results. The self-diagnosis function continuously monitors high-voltage and impulse output status, automatically detecting abnormalities to protect both the instrument and the device under test.
With flexible burst mode options (synchronous or asynchronous) and free phase angle setting from 0-360°, engineers can simulate precise disturbance scenarios without compromising test efficiency.
