Filter combinations

Filter combination – a comprehensive package to reduce interference and save costs

With the filter combination from REO, a three-phase line choke and an EMC filter are combined. This combination will minimise EMC problems and harmonics and will reduce energy costs by up to 20%.

The line choke is responsible for removing stress from the supply network by compensating for the harmonic reactive power. In this way, the harmonics and the commutation notches in particular will be significantly reduced.
With the usage of the three-phase mains filter, interference pulses and surge voltages are interference suppressed in accordance with EN 55011 and EN 618003.
