Product Description

3 Phase Online Soft Starter No Need To Built By Pass Contactor



Online soft starter information



ST200 motor soft starter is a new type motor starting and protection device that is integrated with power electronic technology, microprocessor and automatic control. This soft starter is able to steadily start and stop motor without step change so as to avoid mechanical or electric impact resulted from using conventional starting modes such as direct starting, star-delta starting and auto voltage reducing starting, and effectively reduce starting current and distribution capacity for fear of more investment on capacity expansion.

No need to built by pass contactor with SCR controlling new technology applying.----innovation and cost saving.



Soft Starter Features



Multiple motor protection function


v Phase missing protection

v Over heat protection

v Over current and over load protection

v Output unbalance protection

v Under voltage and over voltage protection

v Load circuit protection

v Under load protection


Minimise fault Maintenance of online soft starter without built by pass contactor


v Free of the maintaining of contactors due to reduce the by pass contactor with SCR controlling new technology.

v Reduce the installation room

v Less the wiring and connection problST200

v Labor cost saving

v No contactor fault problST200
