1. EM-GS Series Soft Starter
1.1 Motor soft starter profile
Intelligent motor soft starter, the use of intelligent digital control; With the single chip processor as the intelligence
center, thyristor module for actuators for full automatic control motor. It applies various squirrel-cage asynchronous
motor control of load, the motor can smooth starting under any working conditions, protect the drag system, reduce
the starting current impact on power grid, ensure reliable motor starting. Smoothly soft stopping function can
effectively solve the inertial system surge problem, eliminate the drag system of inertial impact, that is traditional
equipment cannot be achieved. Intelligent digital motor soft start equipment system with the complete protection
function, extend the service life of the system, reduce the cost of system cost, improve the reliability of system and
compatible with all the functions of starting equipment; It is a new ideal alternative for traditional star triangle
starter and self-coupling decompression starter.
1.2 The main function

Effectively reduce the starting current of the motor; Can reduce the distribution capacity, avoid grid expansion
investment.

Reduce the starting stress of motor and load equipment; Prolong the service life of the motor and related
equipments.

Soft stopping function can effectively solve the parking surge problem of inertial systems; That is a traditional
starting equipment cannot be achieved.

With six unique starting mode; To adapt to the complex motor and load, achieve perfect priming effect.

With complete and reliable protection function; effectively protect the safety of motor and related production
equipment.

Intelligent motor soft starter, the application of network technology used motor control technology to adapt to
the rapid development of electric power automation technology in the higher requirements.
1.3 The main feature of soft starter
Reliable quality

The computer simulation design.

SMT production process.

Good EMC performance.

The machine before delivery on the high temperature aging, vibration test.
Perfect and reliable system protection function

Protection of no voltage, less voltage and over voltage.

Protection of overheating and starting time too long.

Protection of Input phase lost, output phase lost and 3phase unbalance.

Protection of starting over current, running overload, and load short circuit protection.
Maintenance function

Fault self-diagnosis(short circuit, over voltage, less voltage, one phase grounded, motor overload, one phase lost,
motor blocked, and intelligent software can inspect drag system working state).

Combination of modular design, according to the fault display content, quick troubleshooting.
