WK200 AC Drives Description
※ WK200 Variable Frequency Inverter Overview
– Based on the market demand of small power, small size and easy speed regulation, the mini AC drive is targeted. As a compact AC drive with small size and large capacity, WK200 has significant advantages such as high power density, high EMC specification design and high reliability.
– WK200 widely used in transportation belts, automated production lines, automatic doors, wood processing, optical grinding, food processing, pharmaceutical centrifuges, logistics equipment, ceramic equipment, sewage treatment, constant pressure water supply, textile and other small automated machinery.
※ WK200 Variable Frequency Inverter Features
● Integration of speed and torque control
Torque and speed control performance- to ensure smooth mechanical operation, rapid response, small torque pulsation.
● Adaptive Vector Control
Vectorized performance with VF convenience. Motor parameters insensitive, no self-learning required.
● Protection Functions
With hardware protection functions such as output-to-ground short circuit protection, internal buffer relay protection, fan drive circuit protection, motor overload protection, phaseloss protection, overheat protection, overvoltage protection, overcurrent protection, undervoltage protection, etc., it realizes all-around protection for the internal and peripheral devices of AC drive.
● Superior overvoltage suppression
The overvoltage suppression function prevents the AC drive from overvoltage faults caused by an increase in bus voltage.
● Superior overcurrent suppression
The overcurrent suppression function prevents the AC drive from overcurrent faults due to sudden loads or disturbances, and reduces the damage caused by unexplained shutdowns.
● Maintenance Tools
Complete monitoring, configuration, optimization and diagnostic services are provided by FGAppStudio running on PC tool.
※ WK200 Variable Frequency Inverter Structural & Hardware Features
● Easy Maintenance
Features an easy-to-maintain removable cooling fan that can be easily installed and removed.
● Advanced Thermal Design
Wide tooth surface heat dissipation and high air velocity design ensure that the full-power AC drive can be used in a high-temperature environment without capacity reduction.
● Small and compact design
Optimal power density design, effectively minimize the product volume; support for wall-mounted installation, DIN-rail installation, to adapt to a variety of installation environments.
● Removable keyboard
