Newest generation of 690/600 DV/DT filters

Protecting motor windings against excessive voltage peaks and inadmissible voltage pulse rise times generated by the inverter PWM output voltage, is the FN 5060 HV standard DV/DT filter series from Schaffner. DV/DT filters are required to fulfil the IEC 60034-17/-25 standards defining the limits for IEC-and NEMA AC-motors and prolonging their lifetimes.

Schaffner, introduces the new FN 5060 HV standard DV/DT filter series for 690/600VAC motor applications. These innovative filters are designed according to Schaffner’s patented concept which enables DV/DT filter damping performance without using resistors or capacitors. This simplifies the installation, saves mounting space and is a reliable long life time solution.

The new filters are designed to offer minimum power loss, low voltage drop and thus help to maximise the system efficiency.

Several industries can benefit from the use of the new 690/600VAC DV/DT filter, including chemical, cement, metal, oil and gas and, mining as well as applications in buildings and infrastructure environments (pumps, fans, HVAC) and other industries.

DV/DT filters are not only for use in areas where pumps and fans are controlled by drives with short motor cables, but are also recommended to be used for applications with frequent braking, danger of flash-over voltage and motors running at high temperature.

New and existing motors and installations will benefit from a longer life time and a continuous long lasting operation, if Schaffner DV/DT filters are used with variable speed drives.

The standard 690/600VAC filter series are available with current ratings from 16-1,200A. Higher or other ratings can be engineered and delivered on demand. All models are CE, UL, CSA and ENEC approved and RoHS compliant.
