Product Description
Variable Frequency Inverter Three Phase Power Frequency Converter 

Product features:
   High-accuracy: Accuracy of open-loop control can reach ±0.2%. Accuracy of close-loop control can reach ±0.02%
   High torque :0.5Hz/150%,0Hz/180%
   Fast response of torque:control mode of open-loop torque:response time of torque <20ms;control mode of close-loop torque:response time of torque <10ms;
   Fast speed response;
   Internally installed DC braking function. Fast stop is applicable.  
   Stronger function:the function that instant  power down cannot cause machine halt, trace of revolving speed and restart function, droop control function, torque control function, etc.

Advantage :                                           
Big savings on installation: SU220 can be positioned close to the motor which cuts the cost of shielded motor cables. Choose the version with integrated insulator to simplify your external connections.
Big performance: SU220  is a modern sensorless vector inverter with 200% overload capacity, a wide range of supply and fieldbus options, and excellent I/O.
Big advantages of easy handling: SU220 inverters integrate the EPM memory module - a simple plug in chip that stores all the drive settings. The EPM module can be programmed off-line and the settings transferred from drive to drive in seconds. In the unlikely event that a drive fails, the EPM guarantees you minimum downtime.
