Product Description

Medium Voltage Variable Frequency Converter

Product Feature

Perfect harmonics free	Delta connection, output phase of each phase has a difference of 12 electric degrees, which is equivalent to 36 pulse rectifier,eliminating harmonics effectively.can meet the GB14549-93 and IEEE519-1992 voltage and current harmonic distortion requirements
High power factor	Power factor can be more than 0.95 at full speed
Good output waveform	Multiple PWM voltage output,provide sinusoidal output voltage.avoid motor overheat and motor derating.Do not increase the motor running noise,can use the conventional motor and cable without additional requirements
To achieve the motor's soft start	System acceleration/deceleration time is set by user; the start process will not impact current power grids, which ensure motor runs safely and prolongs its service life.
High reliability	Can suppress many current faults automatically, The power unit is composed of high voltage power IGBT;Key electronic components and parts improve the reliability of the power unit effectively by the high temperature aging test;When there is a failure, the power unit goes to bypass automatically to keep system still operating continuously.
High efficiency	Efficiency is more than 95% in total, while the efficiency of frequency conversion part is as high as 97%
Save operation and maintenance costs	reducing motor speed; save energy;reduce the mechanical wear of the motor and load,and save a lot of maintenance costs for the user.
Easy to operate	By pushing the buttons on the cabinet door, the inverter can operates as start,stop, quick stop, and reset control;can be viewed by the signal light; can be displayed on HMI;can be given by main interface or by external analog signal
Perfect protection and auto-diagnosis function	has perfect protection functions like over voltage, over current, phase loss, under voltage, over temperature etc;Monitoring software will show and record abnormal situation during operation.
Rich interface functions	take the industrial computer and PLC as the user interface, which can have extension of analog input/output, digital input/output,serial communication etc.
System bypass function	When fault, automatic bypass, turn power frequency operation function, ensure the production stable and continuous operation.
