Balluff has introduced an energy-saving power supply which, with an efficiency rating of 93 per cent and suitability for high shock and vibration loads, is designed for use in wind-energy equipment.

The semi-potted device has a service life of almost 20 years with an MTBF of 800,000 hours.

It can be connected directly to the generator voltage without need for an intermediate transformer.

It also has optical indicators that display the status and condition of the unit.

Since it tracks dynamic loads, it can be operated continuously even under high load conditions.

This makes reserves of 30-50 per cent no longer needed.

Special sensors, in combination with a microcontroller, continuously monitor wear factors in the power supply such as temperature, overload, faults and other conditions.

Intelligent evaluation of these parameters then gives the user an overview of the status of the unit for implementing maintenance measures, thereby reducing the probability of failure of the overall system.

Coloured LEDs in traffic light colours provide the user with continuous information about the current load level and stress level, as well as the life time, a forecast of remaining life expectancy.

The indicators are bright enough to be reliably seen and interpreted from several meters away.

The usual three-phase transformer used in wind-power equipment can be dispensed with, thereby saving money.

Due to its broad input range of 380-690V, the switched-mode power supply can be connected directly to the generator voltage of the wind turbine.

As a result there is a reduced number of failure-prone parts, along with increased efficiency of the system due to less heat loss.
