Mains Chokes
Advantages of using a mains Choke:
l Less mains disturbance
The wave shape of the mains current approaches sinusoidal; at
the same time the r.m.s. current is reduced by up to 40%
(reduction of the mains load, the cable load and the fuse load).
l Increased life of the Controller
A mains Choke reduces the AC load of the DC bus capacitors
and thus doubles its Service life.
l The transient high-energy overvoltages which are sometimes
generated at the mains side by circuit breakers or fuses are
stopped by the mains Choke and thus the units are usually not
damaged.
l Low-frequent radio interference tan be reduced.
Please note:
l When a mains Choke is used, the maximum possible output
voltage does not resch the value of the mains voltage.
- typicat voltage drop at the rated Point: 4 to 5%.
l Mains Chokes are always required when the Controller is
operated with increased or maximum power.
