The newest generation of 690/600 VAC dv/dt filters

Motor drive output filters protect motor windings against excessive voltage peaks and inadmissible voltage pulse rise times generated by the inverter PWM output voltage. Dv/dt filters are required to fulfill the IEC 60034-17/-25 standards defining the limits for IEC-and NEMA AC-motors and prolonging their life times.

Schaffner, the international leader in the fields of electromagnetic compatibility, power quality and motor drive output filters, introduces the new FN 5060 HV standard dv/dt filter series for 690/600 VAC 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 maximize the system efficiency.

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

Not only to be used in areas where pumps and fans are controlled by drives with short motor cables, the dv/dt filters from Schaffner 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 such dv/dt filters are used with variable speed drives.

The standard 690/600 VAC filter series are available with current ratings from 16 A to 1’200 A. Higher or other ratings can be engineered and delivered on demand.
