With the pitch control system, individual
circuits are supplied from multiple power sources. These supply voltage 400V
DC and are kept constant state readiness via a
management system.

Simple and quick connection
Typically, rechargeable batteries capacitors are used
for energy storage. Users can configure their
own connector. this way, even one the rotor blade
drives fails, the other two rotor blades can still moved
to the braking position. overspeeds can already be
avoided setting just single rotor blade the braking
position, every rotor blade can treated an
independent braking system. For safety reasons, the energy
stores are kept separate location away from the other
electrical systems.
Components the flexible Han-Modular® connector
series can freely combined.reliability and safety when designing and constructing
pitch control systems.
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. With this
system, protection against accidental contact still in
place even when the connection disconnected. In
addition, the HARTING products also offer quick and easy
assembly with risk incorrect mating. counter this type risk HARTING
has developed the Han® E-Protected module.
Another key factor the choice the right product is
