IEC 61000-4-11/4-34 Voltage Dips and Interruptions Generator
Leave a Message
The CSS61000-11 series Voltage Dips and Interruptions Generator is a high-precision test instrument developed by LISUN for conducting voltage anomaly immunity testing on electrical and electronic equipment (EUT). This device simulates common power grid disturbances including voltage dips, short interruptions, and voltage variations, providing standardized test conditions for evaluating equipment stability and reliability under power quality fluctuations.
The CSS61000-11 model provides single-phase output compliant with IEC 61000-4-11:2020, while the CSS61000-11T series offers three-phase output compliant with IEC 61000-4-34:2025 and GB/T 17626.34-2012 standards. The instrument features a large Android touchscreen interface with English and Chinese language support, built-in IEC and GB/T test standards, and one-touch recall of preset test parameters including 50% voltage dips and 100ms interruptions.
Test parameters including dip phase angle (0°-360° with 1° resolution), duration (0.5-9,999.5 cycles), and repetition count (0-9,999 cycles) are fully configurable to meet specific testing requirements. The generator supports automatic test sequences with manual, automatic, and 50ms trigger modes, and can initiate dips on one to three phases simultaneously for comprehensive three-phase testing.
