Low Frequency Conducted Immunity Test System

The LFCI61000-1619 Low Frequency Conducted Immunity Test System includes a range of testing accessories such as co-anti-disturbance test devices, coupling removal network, and current injection device, designed to fulfill various testing requirements. This system facilitates low-frequency common mode and differential mode conducted immunity testing, capable of simulating fundamental frequencies, major harmonics, and interharmonics of power distribution systems or power electronic devices like power converters. Interference can be injected into the grounding system via stray capacitance or coupled onto signal and control lines through induction. Compliant with standards: IEC/EN 61000-4-19 (GB/T17626.19) for immunity to conducted, differential mode disturbances in the frequency range 2 kHz to 150 kHz at a.c. power ports, IEC/EN 61000-4-16 (GB/T17626.16) for immunity to conducted, common mode disturbances in the frequency range 0 Hz to 150 kHz, JJF 1245.4-2019 for AC energy meters, IEC 62052-11 (GB/T17215.211) for electricity metering equipment, and IEC/EN 60255-22-7 (GB/T 14598.19) for electrical disturbance tests for measuring relays and protection equipment. Applications include intelligent meters with PLC data transmission, touch dimming lights, communication systems (Ethernet, ISDN, ADSL modems, IP network branch switches, routers), contactless card readers, credit card terminals, alarm systems, electronic controls (heating systems, streetlights, traffic lights), and household appliances (steam irons, coffee machines, microwaves, washing machines), among others.
