WNG Series Open Frame Power Supplies
Supplier: RSG
Technology type: Open / U-Frame Power Supplies
The basic construction of this switch-mode power supply consists of a bridge rectifier and a push-pull converter. It works as a constant current source with voltage limitation and supplies an inverter and a buffer capacitor. It is designed for a permanent output of up to 5kW. The WNG series can produce 10kW peak output power for 10 seconds. When the maximum current is reached, the output power is limited in accordance with a characteristic curve controlled by the processor.
Due to the installation environment in the hub of wind turbines, the WNG series was designed, tested and certified for high mechanical demands.
Each pitch control system in a wind turbine contains three power supplies as the WNG.
