The A-1650 is an optimized version of the A-1500. This three-blade, horizontal-axis turbine is designed for high performance in various wind and terrain conditions.

The new configuration and rotor sizes improve the output performance of the wind turbine. The A-1650 has a variable rotational speed and full span pitch control and reaches its rated output at a wind speed of 12 m/s.

The combination of electrical torque control and pitch control allows the wind turbine to be operated at a wind speed of 3.5 m/s, with a virtually constant power output from 12 through 20 m/s.

The A-1650 features a new control system, new rotor sizes, robust gearbox construction with integrated rotor shaft, making the unit more compact and silent. The A-1650’s superior performance is the result of:

• New generation of advanced power electronics IGBT converter.
• Larger rotor size for wind class III.
• Access to control system from the bottom of the tower.
• Sophisticated gear system for longer life.
• Compact and robust nacelle.
• Speed and torque controlled by pitch system.
