  • TDKFilter

  • The sine-wave filters from TDK are EMC filters for frequency converters designed to reduce the proportion of high clock frequencies at the output of converters. This allows the interference-free operation of variable speed drives with long motor cables.

    Motors are often connected to converters over distances of more than 100 meters. The parasitic capacitances of such long cables result in reactive power. Motor noises and increased eddy current losses are also produced. TDK sine-wave filters significantly reduce these negative effects. Moreover, they can reduce filtering requirements at the input of the converters, so that less expensive types can be used there.

    Sine-wave filters of the B84143V*R227, *229 and *230 series are designed for continuous currents of 4 to 320A at rated voltages of between 520 and 690V. The permissible clock frequency of the converters is between 2.4 and 16kHz, depending on the type.

    Where it is also desirable to dispense with shielded motor cables, it is recommended to use the B84143V*R127 filter series with SineFormer® technology.

  • TDKFilter

  • The B84142A*166 series from TDK is a series of 2-line EMC filters designed for rated currents of 10A, 16A, and 30A at a rated voltage of 250VAC (50/60Hz). These filters are very compact in size: the 10A and 16A types measure only 84.5x52x38mm, and the 30A version only 130x84x69mm. This permits mounting even when space is very limited.

    Another feature of the B84142A*166 is its extremely low leakage current of less than 0.5mA and 1.8mA. This prevents unintentional tripping of ground fault circuit interrupters (also known as residual current devices). In addition to their compact size, these filters offer a very high insertion loss of up to more than 100dB.

    The new filters meet the requirements for climate category 25/100/21, IEC 60068-1 and protection class IP00. The filters can be operated without derating at ambient temperatures of up to 50°C. Approvals to EN, UL and CSA are pending. Applications for the new EMC filters include converters and power electronics systems.

  • The B84243A8x series from TDK are very compact EPCOS 3-line EMC filters for frequency converters. These high-performance filters are suitable for a rated voltage of 530VAC in 50/60Hz grids. The compact dimensions lie between 90x40x95mm and 250x85x120mm. The B84243A8 series currently comprises seven different types that are designed for currents of between 3A and 60A, based on a rated temperature of 50°C.

    These EMC filters typically perform according to EN 61800-3 C1 and C2 for motor cable lengths of respectively up to 25 meters and 50 meters.

    Apart from their outstanding EMC performance, these 3-line EMC filters also feature very short discharge times. At currents up to 44A the filters achieve a residual voltage of <60V in less than one second. The 3A version with a leakage current of less than 2mA has been specially developed for plug-in devices that must meet low leakage current limits. The other models have leakage currents of no more than 5.1mA and can also be operated in environments with sensitive residual current devices.

    These filters are designed for a high short-circuit current (SCCR) of 100kA in accordance with UL 508. Approvals according to UL, CSA and ENEC are pending.

    Recessed connections permit optimum access to the mounting bracket, making the filters suitable for installation in switching cabinets or where limited space is available.
