1). Infineon IGBT(KT4) 
2). TI DSP chip set
3). Delta Fan
4). Lem Sensor
5). Jianghai Capacitor
6). Super low fail rate,less than 1% even in the hardest working condition.
7). With special tension control software for winder unwinder machine
8). With special software for elevator 

2.Ehanced control and performance

-Starting torque: 180% at 0.5Hz(heavy duty);120% at 0.5Hz(normal duty)-Two control modes:V/F & Sensor less vector control

-Precise speed control stability:open loop magnetic flux vector control≤±0.5%(rated sync-speed)

-Improved speed control stability: open loop magnetic flux vector control≤±0.3%(rated sync-speed)

3.Switchable Dual Rating Operation Mode: Normal Duty/ Heavy Duty

This optio allows users to selected and appropriate operating mode of frequency inverter thjat corresponds to load of induction motor. ? Normal Duty? mode is 150% for 3 sec and 130% for 60 sec.Capacity on continuous operation corresponds to inverter rated capcaity .? Heavy Duty? mode is designed for heavy work applications.Capacity on continuous operations is one step down from inverter rated capcaity.For this mode,overload capacity is 180% for 3 sec and 150% for 60 sec .
