Press Release Summary:
Targeting LV motor applications, FN5060 standard dv/dt filter series protect motor windings against excessive voltage peaks and inadmissible voltage pulse rise times generated by inverter PWM output voltage. Design enables dV/dT filter damping performance without using resistors, simplifying installation andÂ conserving mounting space. RoHS-compliant products, approved by CE, UL, CSA, and ENEC, carry 12–1,100 A ratings; higher ratings can be engineered on demand.
Original Press Release:
Schaffner Introduces the Newest Generation of 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 IEC60034-17/-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 FN5060 standard dv/dt filter series for LV motor applications. These innovative filters are designed according to Schaffner’s patented concept which enables dv/dt filter damping performance without using resistors. This simplifies the installation and saves mounting space.
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 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 motor drive generations control motors more often with higher switching frequencies. Therefore output filters, such as dv/dt or sine wave filters are required to ensure a continuous and long lasting operation.
The standard filter series are available with current ratings from 12A to 1,100A. Higher ratings can be engineered and delivered on demand.
All models are CE, UL, CSA and ENEC approved and RoHS compliant.
