Suitable for climatic conditions

The robust and compact controller has proven itself in the required applications. Their design can withstand temperature fluctuations, condensation, vibration, salt spray, or dust.

Wind turbine manufacturers particularly appreciate specific production and development technologies. Within the scope, over 20000 compact control systems operate reliably under environmental conditions that commonly have adverse effects on electronic devices in the cabin. They are used for blade angle control (pitch control) and condition monitoring.
