Schaffner has expanded its line of dv/dt filters to include the FN5060HV which protects AC motors up to 690/600VAC from destructive effects of peak voltages and inrush amps. This patented technology protects motors and adjacent equipment without capacitors or resistor. They efficiently reduce high output dv/dt from IGBT motor drives and eliminate over-voltages caused by line reflections on motor cables, per IEC 60034-17/25. Typical dv/dt reduction is a factor of 8 to 12.
These filters are ideal for loads up to 690VAC, 30 to 1200A, and motors up to 60 Hz. They are also well suited for motor drives with short to medium cable lengths, applications with frequent braking, danger of flash-over voltage, and applications where motors are running at high temperature. Industries where these types of applications are common include chemical food and pharmaceutical processing, cement, metalworking, oil and gas, mining, and more. Applications include servo or torque motors, submersible or irrigation pumps, HVAC equipment including pumps, fans and compressors, and more.
According to the company, a compact, resistor-less design saves floor mounting space and installs easily. With minimum power loss and low voltage drop, they maximize system efficiency. Schaffner dv/dt filters are ideal for newer, high-frequency motor drives. These UL, CE, CSA, and ENEC approved and RoHS compliant models are available through Schaffner channel partners throughout North America.
