PLC blocking filters target smart grids

June 23, 2016 // By Julien Happich
The BF series with integrated plastic housing is what Premo claims to be the most compact blocking filter in the market today for smart meters which comply with PLC protocol such as CENELEC Band A, PRIME & G3.

The BF series filters are installed between smart meters and end users for reducing the noise coming from end-user equipment via household wiring. Compliant with EMC regulation EN 50065-1, the filters have been developed with high attenuation without earth or Ground system. They are offered with three kinds of attenuation levels, over 40dB, 30dB and 20dB for reducing all kinds of noise from the end user equipment. The BF-xx-MM models are easy to install into 220Vac to 250Vac 50Hz/60Hz networks. The blocking filters have been developed for single phase systems but can also be used in 3-phase systems with a maximum of 480Vac between phases. Standard models are rated to 20A, 30A & 40A with 250Vac. All models are designed and manufactured according to EMC Directive 2004/108/EC, UL1283, EN60939-2, IEC 60950-1 & RoHS 2011/65/EU.
