Product Description
AC Motor Speed Control Variable Frequency Inverter Frequency Converter

Product features:
 
Higher
   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%
 
Faster:
   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
   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.
More complete
  
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.

Environmental Requirement:
1 Environment temperature range: -10 degree~+40 degree. Controller will be derated if ambient temperature exceeds 40degree.
2 Prevent rain drops, moist environment, oil fog, salt erosion, corrosive gas, etc.
3 Prevent direct sunlight, keep away from radiation source.
4 Prevent violent vibration or sudden impact.
5 Lower than 1000m installation altitude, water pump AC power saver will be deratd when the altitude is higher than 1000m.
