> Three-phase EMC filters available in L1 low-profile type and book type for drive applications
> Small size/light weight, installation area is the smallest class in the industry
> Designed for low leakage current design specifications as required by the Japanese market

TDK Corporation has extended its product range of EMC filters for the Japanese market and now offers the new EPCOS three-phase EMC filters series B84743*R712 for drive applications that are available in L1 low-profile type and book type. TDK-Lambda Corporation will start shipping from August 2020.

The filters are available in the currents 80 A up to 150 A with a small mounting footprint and – as required by the Japanese market – low leakage currents based on 200 V AC delta connection mains with one corner grounded. Furthermore, two types of leakage current have been set by the Y capacitor (ground capacitor): 2 mA / 9.4 mA; 200 VAC / 60 Hz, delta connection. It is also possible to meet the attenuation effect required by customer.

The rated voltage specification of the B84743*R712 is 520 V (maximum voltage in 3 phase), and three rated current models (80/100/150 A) are available. This is the first time that L1 book type is added to the product lineup.

This product development focuses on space-saving and weight reduction with the industry’s smallest class of installation area: 240 x 130 x 80 mm for 80 A type, 270 x 130 x 80 mm for 100 A and 310 x 130 x 90 mm for 150 A type for L1 version (low profile – dimensions always with terminals). Compared to current products, the low-profile type saves space by 40% and is 45% lighter, contributing to downsizing and space-saving of the end equipment.

Main applications
Drive system (servo/inverter), factory automation, semiconductor manufacturing equipment, industrial equipment

Main features and benefits
> Suitable for drive system
