Sine filter SFB 400/250

Highlights

• Prevention of overvoltages on the motor
• Long cable lenghts possible
• Reduction in motor noise
• Reduction in line-borne and field-borne emitted interference
• Reduction in motor losses
• Very good corrosion protection and low noise thanks to vacuum impregnation

Anwendung

• Sine filter for the suppression of differential mode interference
