Passive EMI filters from BLOCK are used to suppress the electromagnetic interference between the network and frequency inverter in the frequency range between 150 kHz and 30 MHz. They ensure compliance with the limit values required under residential and industrial standards.
In the line filter design, the passive EMI filter can also be combined with a line reactor, which also reduces low-frequency interference (harmonics).
Overview:
◼︎ Attenuation of radio interference voltages >=150 kHz
◼︎ Compliance with the limit values required under residential and industrial standards
◼︎ Flawless operation of 30 mA/300 mA ground fault circuit breakers through the use of low-leakage current filter solutions
◼︎ Increased interference immunity for the system
