PSTX570-600-70软启动器是一种集电机软起动、软停车、轻载节能和多种保护功能于一体的电机控制装置, 国外称为Soft Starter.它的主要构成是串接于电源与被控电机之间的三相反并联闸管及其电子控制电路.运用不同的方法, 控制三相反并联闸管的导通角, 使被控电机的输入电压按不同的要求而变化, 就可实现不同的功能. 

PSTX570-600-70软起动器和变频器是两种完全不同用途的产品.变频器是用于需要调速的地方, 其输出不但改变电压而且同时改变频率;软起动器实际上是个调压器, 用于电机起动时, 输出只改变电压并没有改变频率.

PSTX570-600-70变频器具备所有软起动器功能, 但它的价格比软起动器贵得多, 结构也复杂得多。

PSTX570-600-70The soft starter is a motor control device that integrates motor soft starting, soft parking, light load energy saving and various protection functions. It is called Soft Starter abroad. Its main component is connected in series between the power supply and the controlled motor. The three-phase parallel thyristor and its electronic control circuit are used. Different methods are used to control the conduction angle of the three-phase parallel thyristor so that the input voltage of the controlled motor changes according to different requirements, so that different functions can be achieved.

PSTX570-600-70Soft starters and frequency converters are two products with completely different uses. Frequency converters are used where speed control is required, and their output not only changes the voltage but also the frequency at the same time; the soft starter is actually a voltage regulator, used for motor starting. When , the output only changes the voltage and does not change the frequency.

PSTX570-600-70The frequency converter has all the functions of a soft starter, but its price is much more expensive than a soft starter and its structure is much more complex.
