Description
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.
