Overview

EN 61000-4-14:1999/A2:2009 (equivalent to IEC 61000-4-14:1999/A2:2009) is a CLC/CENELEC amendment specifying a standardized voltage fluctuation immunity test for electrical and electronic equipment with input current not exceeding 16 A per phase. It defines test sequences, timing, and generator characteristics used in electromagnetic compatibility (EMC) testing to evaluate equipment immunity to short-term voltage changes (dips, swells and steps).

Key topics and requirements

• Scope: Voltage fluctuation immunity test applicable to equipment with input current ≤ 16 A per phase.
• Test sequences: Repetition period T = 5 s and fluctuation duration t = 2 s (Figure 1d). Changes use five successive voltage steps spread over five mains cycles.
• Step size and timing:
  • Each voltage change is in five steps of magnitude ΔU/5.
  • Each step occurs over π/2 radians (~5 ms at 50 Hz).
  • Falling steps start at phase angle φ = 270° → 360°; rising steps start at φ = 180° → 270°.
• Open test level: An “x” level is left open for product standards to define situations beyond normal supply conditions; for public supply equipment values shall not be below class 2.
• Test generator characteristics (Table 2 highlights):
  • Output voltage capability U ±15%
  • Voltage accuracy ±1%
  • Zero-crossing accuracy ≤ 250 µs
  • Overshoot/undershoot < 5% of the applied change
  • Voltage rise/fall time during switching < 1 ms
  • Maximum interphase error (3‑phase) 2.5°
  • Frequency accuracy ±2.5% of nominal (50/60 Hz)
  • Output current capability sufficient for the EUT and capable of crest factor ≥ 3 during verification
• Verification:
  • Generator verification with a resistive load equal to the generator’s current capability (example: 230 V / 16 A → 14.3 Ω).
  • Example verification load circuit (Figure 4) uses a bridge rectifier, an 11 000 µF ±20% electrolytic capacitor, a 61 Ω ±1% resistor and a specified series resistance target (92 mΩ ±10%).

Applications and users

• Intended for EMC test laboratories, product manufacturers, design and compliance engineers, and standards committees to:
  • Verify immunity of appliances, consumer electronics, industrial equipment and medical devices (where input ≤16 A) against mains voltage fluctuations.
  • Develop product-specific test levels and ensure conformity with public supply immunity classes.
• Useful when validating power-supply robustness, firmware/software behavior under supply variation, and compliance evidence for regulatory or market access.

Related standards

• IEC/EN 61000-4-14 (base publication and amendment A2)
• IEC 61000-4-11 (noted as suitable for test generators with power amplifiers)
• Other IEC 61000 series EMC test methods and product-specific standards that may set required test levels

Keywords: EN 61000-4-14, IEC 61000-4-14, voltage fluctuation immunity, EMC testing, 16 A per phase, voltage dips and swells, test generator verification.
