VF SVC control Variable Frequency Inverter for three phase motor AC
drive
1. Features of variable frequency drive VFD500 series for your
reference
1. Compact size to help save the shipping space and cost. VEIKONG
continues to make applications even smaller by combining the
compact designed drive with the light, efficient design of a
synchronous motor.
2. Ripad response to impact loads. When it meets with sudden load
change, inverter can quickly restore the speed, reduce the speed
fluctuation, and ensure the production stability and high quality
finished products.
3. Perfect protection system to protect your motor and the whole
device. Designed for 10 years of maintenance-free operation.
Cooling fan, capacitors, relays, and IGBTs have been carefully
selected and designed for a life expectancy up to ten years.
