The Enerdoor FIN905SF.115.M is a sine wave filter engineered for variable frequency drive (VFD) applications. It provides excellent attenuation and performance across a range of frequencies and currents, making it suitable for motor protection.
This filter operates with a nominal voltage of 600V and handles a rated current of 115A. Key technical specifications include an output frequency range of 0-100 Hz and a carrier frequency (PWM) greater than 4 kHz. It is designed for an ambient temperature of up to 70°C and can operate at altitudes up to 1000m with relative humidity below 95% (non-condensing).
The FIN905SF.115.M features low power loss and does not require ventilation. Its compact design is available in various enclosure options, including Terminal (M) and Nema 1 (IP20) or Nema 3R (IP54) enclosures. The filter is beneficial for long cable applications, process plants, water treatment plants, VFDs, and agriculture.
Electrical characteristics include a power loss of 57W at 115A, a minimum switch frequency of 4 kHz, and compatibility with solid cable sizes from 0.2-10 mm² and stranded cable sizes from 10-50 mm². The terminal block torque is specified at 4.5 Nm.
The nominal voltage rating is 600V.
The rated current is 115A.
The output frequency range is 0 to 100 Hz.
The maximum ambient temperature is 70°C.
The IP rating is IP20 up to 180A and IP00 over 260A.
