タイトルまたは説明

AS**0 series four-quadrant cabinet is designed for the field of industrial lifting, such as a large crane, gantry crane, quay crane, bulk cargo cranes, etc.; It can also be applied to the field of process control, such as paper making, metallurgy, mining, cement, energy, chemical, oil and gas industry.
AS**0 series four-quadrant cabinet is highly flexible AC transmission products, with the following significant features: Can be customized to meet the needs of individual users; A wide range of power and voltage, including up to **0V industrial voltage; A variety of built-in optional; Can be programmed to adapt to different application requirements.
Features:
Complete energy regeneration drive
AS**0 Series is a compact cabinet drive which configured with energy renewable power supply unit. The drive includes all devices with energy renewable supply and line side filter. Energy renewable power supply unit allows the energy to switch between the motor and generator mode.
Energy saving
Compare to other braking methods (such as mechanical braking, resistance braking), AS**0 is more energy-efficient. Energy renewable transmission has significant energy-saving advantages, with the function of energy direct feedback to the grid without heat consumption. Because it doesn't require an external braking resistor, so the installation is simple and it occupy small space.
High performance
AS**0 conversion in the electric mode and the modes of generation is very fast, which is a fast control performance of the vector-based technology. Renewable energy power supply unit can improve the output voltage, even if the voltage is lower than the rating, you can still output full scale rated voltage. Renewable energy based on vector control power supply unit can also compensate for the moment fluctuations in the grid voltage. Therefore, even if the supply voltage drops, the device will not damage or fuse will not blow.
Wide applications
AS**0 standard configuration can meet the requirement of different applications. The cabinet drive series have a wide range of features and built-in options.
