To ensure stable and reliable operation of a wind turbine, the power supply is critical.

Most standard industry power supplies are not designed to cope with the real-life

operation demands of a wind turbine – operation temperature span, mechanical

robustness, tolerance towards ESD/EMC, etc. That is why DEIF Wind Power Technology

has designed a series of rugged DC supplies to support the second-to-none reliability

of our control systems.

Reliable DC power for critical control applications

To ensure stable and reliable operation of a wind turbine, the power supply is critical.

Most standard industry power supplies are not designed to cope with the real-life

operation demands of a wind turbine – operation temperature span, mechanical

robustness, tolerance towards ESD/EMC, etc. That is why DEIF Wind Power Technology

has designed a series of rugged DC supplies to support the second-to-none reliability

of our control systems.

The power supplies feature compact and lightweight switchmode design and at the

same time – similar to conventional transformer designs – they have no moving parts

as they have been designed for convection cooling. Thus no maintenance-demanding

fan is required.The wide range DC-input option spanning from 180 to 480VDC enables

direct connection to all common energy storages and makes the DPS-1 extraordinarily

suitable for pitch applications.

The DPS-1 series of power supplies is designed for an operation temperature range

of -40˚C to +70˚C, supporting reliable start-up and operation regardless where in the

world the wind turbine is operating.

The MVR-F215 feeder protection relay is ideal for application which require current and voltage

based protection like directional feeder protection. The device supports IEC 61850 communication.
