There’s always a way
to get things going again:
Emergency Power Supply.

Pitch Systems>Our Pitch Systems>Emergency Power Supply

In an emergency or during unexpected downtimes, the pitch system must be capable of returning the rotar blades at a fixed speed to a safe 90° position. Even during a network failure. This is one of the directives established by Germanischen Lloyd. For us it’s a given. Of course the pitch system then requires an uninterrupted power supply (UPS).

 

This is accomplished with batteries or ultracapacitors. And because we never make compromises when it comes to safety, we offer both technologies and recommend the optimal system for your WTG type. Ranging from voltages of 144 V, 216 V, 288 V … you need only remember one figure: 100 %. That is the only acceptable safety standard when it comes to your WTG. 


Fast and robust:
Our ultracapacitors.

  • Short recharging time
  • Very long service life (10 years+)
  • Insensitive to temperature
  • Rated voltage of 2,5 – 2,7 V
  • Series connection at high voltages: e.g., 60 2,5 V capacitors = 144 V
  • Optimized chargers and overvoltage module for reliable function over many years

Simple and efficient:
Our batteries

  • High energy density
  • Low production costs
  • Simple charging
  • Rated voltage 12 V / 7.2 Ah
  • Series connection at high voltages: e.g., 18 12 V batteries = 216 V
  • Integrated voltage monitoring
  • Temperature monitoring by PT100 relay
