Modular design, flexible expansion
The future oriented driving concept allows users to continuously innovate within the same frequency converter system. Outstanding maintenance and repair friendliness. Application: Flexible driver, suitable for various applications * Integrated security protection functions, products with SS1 and SLS functions.

Based on integrated security protection technology, equipment operation is safer and easier.
Due to the integration of security protection functions, the purchase and construction costs of automation and drive systems with security protection have been greatly reduced. It also effectively ensures human-machine safety. Application: Production machinery (packaging machines, textile machines), material transportation machinery, etc.
PROFIBUS and PROFINET bus standards - integrate these two bus communications directly into the frequency converter.
The advantages of PROFIBUS and PROFINET, which have higher performance with more nodes and multiple network topologies, are not only that they are widely used buses by many users, but also reflected in their optimized engineering and configuration structures. They enable mature IT technologies to be applied in the industrial field and office tools to be used in industrial control.
Application: Remote control of production lines and transmission equipment (such as in the automotive industry).
Regenerative energy feedback capability: within the output power range *.
Energy saving, space saving, no need for braking resistors. By adopting innovative power modules, optimized energy feedback can be achieved. Full power range can achieve commutation rectification without generating any system interference. And the required line current is small, reduced to 80% compared to conventional frequency converters.
Application: Suitable for driving vehicles, centrifuges, and other production machines with high moments of inertia.
Adopting a new cooling concept greatly enhances robustness.
Cooling the power module through external heat sinks results in high heat dissipation efficiency.
The heat dissipation of the power part is entirely completed by external heat sinks, while the cooling of the electronic part is achieved through system convection, making it suitable for more demanding climate environments. The electronic part has added a strong coating.
Application: Suitable for applications with harsh climate conditions and air pollution, such as the textile industry
Provide 690V selectable options
Application: Standard input voltage suitable for basic and process industry applications
