The high requirem ents placed these connection

Another key factor the choice the right product is
working safety. extensive range modules available

which are top the list for the products the Han®
family connectors. For safety reasons, the energy

In order avoid single fault resulting simultaneous
failure all three adjustment mechanisms, the controls
of the individual rotor blade drives are realized separately
from each other. these
modules have one thing common: reliability and safety
are the main priority.
Power supply the adjustment mechanisms provided
via the power distributors the wind turbine. this way, even one the rotor blade
drives fails, the other two rotor blades can still moved
to the braking position.
Simple and quick connection
Typically, rechargeable batteries capacitors are used
for energy storage.
Components the flexible Han-Modular® connector
series can freely combined. overspeeds can already be
avoided setting just single rotor blade the braking
position, every rotor blade can treated an
independent braking system. counter this type risk HARTING
has developed the Han® E-Protected module. result, connecting cables are
required between the components (often control cabinets).
