The Enerdoor FIN905SF.180.M is a sine wave filter designed to provide excellent attenuation for variable frequency drive (VFD) applications. This filter is rated for a nominal voltage of 600 Vac and a rated current of up to 180A at 40°C, with a reduced rating of 145A at 50°C. It operates with an output frequency range of 0 to 100 Hz and a carrier frequency greater than 4 kHz.
The filter is designed for low power loss and does not require ventilation. It is suitable for long cable applications up to 2,500 meters and is used in process plants, water treatment plants, and agriculture.
The ambient operating temperature is rated up to 70°C at an altitude of 1000m, with relative humidity below 95% without condensation. The saturation current is rated at 4x the rated current during switch-on, 2x In for 10 seconds, and 1.5x In for 10 minutes. The ingress protection is IP20 up to 180A and IP00 for currents over 260A.
The nominal operating voltage is 600 Vac.
The rated current is 180 A at 40°C ambient temperature.
The ambient temperature rating is 70°C.
The minimum switching frequency is 4 kHz.
The filter has IP20 protection for ratings up to 180 A.
Solid cables from 3 to 95 mm² and stranded cables from 35 to 95 mm² are supported.
