ST100 Digital Soft Starter
KEWO ST100 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.

Control power: AC110V--220V+15%
Three-phase power supply: AC380V, 660V, 1140V±30%
Nominal current: 15A-----1000A, totally 22 kinds of rated values.
Applicable motor : General squirrel cage asynchronous motor .
