Schaffner has reintroduced its FN2415 single-phase EMC filter for control equipment, and it features extended capabilities. Large and complex machine tools with multiple driving axes and very long motor cables can suffer from reliability problems caused by the internal coupling of interferences from the drive system to the control wires. This can cause dropouts, and it also interrupts the control unit and can consequently lead to the unnecessary and costly downtime of a machine. The FN 2415 EMC filter, designed for the control lines of complex equipment and machinery, is stated to eliminate interference which affects PLCs and motion or robot control systems, thus increasing the system stability and reliability of the entire machine. It can also be used, says Schaffner, for diverse single-phase applications such as motor drives and power supplies.
Two new versions with adapted performance and lower leakage currents are now available. The FN 2415 B version with no leakage current (0mA) does not add to the RCD total leakage current in a machine or a cabinet and may be used in medical equipment. The FN 2415 L, with a leakage current of less than 3.5mA, is suited to low-leakage applications, allowing the use of RCDs rated at 30mA in complex machines where several 3.5mA leakage current filters may be connected in parallel. Schaffner claims that with its EMC attenuation performance, the FN 2415 "Contributes significantly to the achievement of electromagnetic complianc", e.g. EN50370-1 standards for machine tools.
The compact design of the FN 2415 provides simple and time-saving installation with good accessibility for automatic and hand tools. Solid, touch-safe terminal blocks offer sufficient contacting cross section according to the EN60204-1 installation standard. The filters are IP20 rated and have an operating temperature range of -25degC to +100degC. The filters have all the required safety approvals (UL, CSA and IEC / EN) and are compliant to REACH and RoHS directives.
