Manufacturer: SHIMADEN CO., LTD.
Model:  NF Series

Features

It can reduce and eliminate various noise interferences in general environments. With a reduced size and lighter structure, it achieves about 50% greater compactness compared to traditional models. It exhibits excellent high attenuation characteristics when used with our power regulators. Single-phase types are available in 20 to 200A, and three-phase types in 20 to 600A.
