KEWO EM-GJ Series Soft Starter

1. DRINOEM-GJ3  Digital Soft Starter

EM-GJmotor 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.

Specification:

Control power: AC**0V****0V**5%  
Three-phase power supply: AC**0V, **0V, ***0V±*0%
Nominal current: *5A********0A, totally *2 kinds of rated values.
Applicable motor : General squirrel cage asynchronous motor .

Features:

Multiple starting modes
Current-limiting start, ramp current-limiting start and voltage ramp start can meet the site requirements to the maximum extent and realize the best starting effect.
 High reliability
High performance microprocessor conducts digital processing for signals in control system, avoiding the excessive adjustment to analog line so as to obtain the best precision and execution speed.
Powerful anti-interference performance
All external control signals adopt optoelectronic isolation and are set with different anti-noise levels. The device is applicable for use in special industrial environment.
Optimized structure
The unique compact structure is designed to be easily integrated into users existing system, saving expenses for restructuring of system.
 Motor protection
Multiple motor protection functions such as over-current, /output phase-failure, short circuit of thyristorand overheat protection can guarantee motor soft starter not to be damaged in case of fault or incorrect operation.
 Easy maintenance
Pilot signal coding system composed of *-digit number display monitors working condition
Typical Applications
• Bow Thruster, • Compressor, • Elevator, • Centrifugal pump
