Du/dt electronic filter VLT® MCC 102

low-passpassivepower

VLT® dU/dt Filter MCC 102 • Reduces the dU/dt values on the motor terminal phase-to-phase voltage • Positioned between the AC drive and the motor to eliminate very fast voltage changes • The motor terminal phase-to-phase voltage is still pulse shaped but its dU/dt values are reduced • Reduces stress on the motor’s insulation and are recommended in applications with older motors, aggressive environments or frequent braking which cause increased DC link voltage • VLT® FC series family look • Line voltage and filter current: • * For higher power ratings, combine multiple modules. • Enclosure ratings: • IP00 and IP20/IP23 enclosure in the entire power range • IP54 enclosure available up to 177 A VLT® dU/dt filters are placed between the AC drive and the motor to eliminate very fast voltage changes.The motor terminal phase-to-phase voltage is still pulse shaped but its dU/dt values are reduced. • These filters reduce stress on the motor’s insulation and are recommended in applications with older motors, aggressive environments or frequent braking which cause increased DC link voltage. • VLT® FC series family look
