AS500 Series High-Performance Heavy-Duty Vector VFD


Performance Features :

Efficient and Energy-Saving Operating Mode

AS500 VFDs are designed to be highly efficient, incorporating advanced energy-saving operating modes and innovative PWM dead-time compensation technology. This allows the VFDs to reduce motor loss and minimize power consumption, helping to improve overall energy efficiency and reduce operating costs.


Rapid Dynamic Response

The advanced motor model used in AS500 VFDs allows for quick and accurate response to sudden changes in load, providing superior control and stability even in challenging conditions.


Smooth Tracing Start

Provides smooth and impact-free starting of rotating motors, ensuring that your equipment operates safely and efficiently at all times. With our advanced soft-start technology, AS500 VFDs gradually ramp up the speed of the motor, preventing sudden torque and minimizing stress on the motor and other components.


Strong Grid Adaptability

Equipped with automatic voltage regulation capabilities, ensuring that the output voltage remains constant even in the event of fluctuations in grid voltage. With this feature, AS500 VFDs can automatically adjust the output voltage to maintain a stable and reliable power supply, even in challenging conditions.


Considerate Application

High-speed upgrade: When it is light load or no load, the inverter will calculate the maximum speed atomatically according to the load in order to improve the efficiency of the equipment.

PID control: The special menu is used for setting PID parameters and for calculating inside the converter, eliminating the need of an independent external regulator option.

DC braking before operation: When the rotational direction of the motor is uncertain in free slide, it adopts DC braking and automatically restarts the motor after stopping.

Multi-speed operation: Based on signal combinations, operating at the internally-set frequency (16-speed instructions at most) .


Reliable Protection

Motor Protection :

Motor over-temperature protection (PTC): This feature monitors the temperature of the motor and will automatically shut down the VFD if the temperature exceeds safe limits.

Locked rotor protection: In the event that the motor becomes locked or stalled, our VFDs will detect this condition and automatically shut down to prevent damage to the motor.

Motor overload protection: Our VFDs are equipped with advanced overload protection capabilities, which monitor the motor's current draw and will shut down the VFD if the current exceeds safe limits.

Open-phase protection for motor: This feature detects when one or more phases of the motor's power supply are missing, and will shut down the VFD to prevent damage to the motor.

Speed limit protection: Our VFDs allow you to set maximum and minimum speed limits for your equipment, ensuring that your motors operate within safe and efficient ranges at all times.
