KEWO EM-GW Online Soft Starter

EM-GW 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.

Specification:

Three-phase power supply: AC380V, 690V, 11kw to 250kw.

Provide online soft starter cabinet for above 320kw.

Applicable motor : General squirrel cage asynchronous motor .

EM-GW soft starter Features:

Fully and perfect protection function

Configure multiple motor protect function to ensure motor long term running well.

Phase missing protection

Over heat protection
