TDK Introduces High-Current EMC Filters with Exceptional Attenuation Characteristics
TDK introduced its series of new EPCOS 3-line EMC filters for converter applications with high currents that have high attenuation figures, achieved in the range of 9 kHz to 150 kHz. Depending on the type, they are designed for rated voltages of 305/530 V AC and 440/760 V AC (50/60 Hz) at rated currents of 160 A to 2500 A.
In order to meet the requirements of UL in switch cabinet construction, the complete filter series has been designed for an SCCR (Short Circuit Current Rated) value of 100 kA. Despite the high performance, the housings with the IP00 degree of protection are very compact in size. The smallest model, for example, measures 350 x 240 x 120 mm (L x W x H), and the biggest is 710 x 365 x 257 mm. The earth leakage currents of all types are 46 mA, according to IEC 60939-1:2010. Approvals under IEC 60939-3, UL 60939-3, and CSA C22.2 No.8 have been issued.
Typical applications for input filters include frequency converters for motor drives, wind turbines, and power supplies.
The main features and benefits of these filters include:
- Rated voltages of 305/530 V AC and 440/760 V AC (50/60 Hz)
- Rated currents of 160 A to 2500 A
- Very high attenuation figures ranging from 9 kHz to 150 kHz
- SCCR value of 100 kA
- ENEC, UL and CSA approval
