We give you our word – we make electricity safe

Bender Vertretungen weltweit

Quality made by Bender worldwide with special reference to electrical safety is a promise to our customers and to all those we would like to make our customers.

We are committed to using innovative technologies to find solutions for your particular sector and application in order to guarantee the ultimate in electrical safety for people and machines.

State-of-the-art semiconductor technology is widely used today, not only in industrial applications. Almost every common household light source (energy-saving lamp) or power supply unit produces network disturbances which have not existed to this extent a few years ago. As a result, the quality of the power supply is substantially affected. The new Bender devices of the PEM series (Power Quality and Energy Measurement) allow you to keep a clear overview!
