Why Choose DeltaFaraday?

DeltaFaraday supports the complete lifecycle of EFT and burst test equipment—from initial system design through purchase, rental, integration, verification, repair and laboratory expansion.

Complete Systems, Not Just EFT Generators

An EFT generator alone does not create a complete IEC 61000-4-4 test station. DeltaFaraday can supply and integrate the coupling networks, capacitive coupling clamp, verification equipment, oscilloscope, safety enclosure, software and monitoring equipment.

Frequently Asked Questions

What does IEC 61000-4-4 test?

IEC 61000-4-4 evaluates the immunity of electrical and electronic equipment to repetitive electrical fast transient and burst disturbances that may occur on power, signal, control and grounding conductors.

What causes electrical fast transients?

Common sources include relay contact bounce, switching of inductive loads, contactors, motors, solenoids, switches and interruption of current in electrical circuits.

What equipment is needed for IEC 61000-4-4 testing?

A complete system generally requires an EFT generator, coupling-decoupling network, capacitive coupling clamp, ground reference plane, test table, verification loads, attenuator, oscilloscope, monitoring equipment and safety controls.

What voltage levels are used?

Common power-port levels include ±0.5 kV, ±1 kV, ±2 kV and ±4 kV. Signal and control ports commonly use lower levels. The applicable product standard determines the required level.

What is the difference between EFT and surge testing?

EFT testing applies groups of short, repetitive, fast-rise-time pulses. Surge testing applies higher-energy voltage and current waveforms intended to represent events such as lightning-related transients and major switching disturbances.

Why is a coupling-decoupling network required?

The CDN applies the burst to the selected EUT conductors while reducing unwanted propagation toward the external power source or auxiliary equipment.

Why is a capacitive coupling clamp required?

The clamp allows EFT disturbances to be coupled onto signal, control and communication cables without making direct electrical contact with the cable conductors.

How is an EFT generator verified?

The generator output is measured through standardized verification loads, attenuators, cables and a suitable oscilloscope. The measured waveform is evaluated for peak voltage, rise time, pulse duration and repetition characteristics.

Does IEC 61000-4-4 use both positive and negative polarity?

Yes. Testing normally includes positive and negative burst polarity according to the applicable test plan.

Can DeltaFaraday provide an IEC 61000-4-4 rental system?

Yes. DeltaFaraday can provide weekly or monthly pre-compliance and rental configurations involving the generator, CDN, coupling clamp, verification equipment, software and accessories.
