QD218 series frequency inverter has compact structure and excellent performance, which is one specially designed for engineering machinery load. With our QD218 series products, it could help our customer to evidently improve the production efficiency. The equipment strictly follow the related international standards such as IEC/EN61800-3,IEC/EN61000-4,IEC/EN60721-3,IEC/EN61800-5-1 and so on.
Characteristics Electronics units are all reliable brands which could serve 10 years. Built-in DC reactor (37kw~500kw) to reduce input current harmonics content (40%) and improve power factor (0.96). Normally without DC reactor, the input current harmonics content is around 80%~100% and related power factor is 0.6. Built-in harmonics filter to reduce the interference of radio and conduction to other equipment. Evident energy saving effect with energy saving mode. The frequency inverter will check the real load and automatically regulate the voltage and current upon the motor to realize the evident energy saving effect. PCB has adopted thickened three anti-paint protection to improve reliability in harsh environments with high moisture, high dust and high anti-fungal properties. LCD Display keypad (Optional accessory) Through advanced flux and speed estimation technology, the equipment could realize flux current and torque current decoupling control to improve the low torque and guarantee 150%starting torque at 0.5Hz. The overall structure adopts the book design
Reliable Hardware Structure
Integrated DC reactor efficiently improves power factor, greatly reduce current distortion,reduce input current value and improve the product stability. Clear LED display to quickly adjust the guide with parameter data upload and download function. It could be installed on the cabinet gate or hold on hand to operate. The latest generation IGBT technology to low down the energy consuming with better characteristics and better short circuit withstand capability. Integrated C3 harmonics filter could efficiently limit electromagnetic interference which could help the equipment apply to all kinds of industrial environments and greatly low down the interference to other equipments on the site. High standard & excellent quality units and thickened painting PCB has efficiently improved the product reliability to ensure safe running in the worst environment. Long service term, low noise, excellent efficiency and detachable fan design to ensure safe running of the system and make clean and replacement easier.. Unique dual duct design: Power cell and control unit separately carry out cooling job to improve the equipment reliability and support parallel installation.
