5. Online Soft Starter Cabinet
EM-GU3I series online soft starter cabinet is suitable for squirrel cage asynchronous motor control with various
loads to ensure reliable start of motor. It has a complete system protection function, extend the service life of the
system, reduces the cost of the system, improves the reliability of the system and compatible with various
functions of all devices. It is a new ideal alternative for traditional star triangle starter and self-coupling
decompression starter.
5.1 Product 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
equipment.
●
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.
Conditions of Use:
●
Power Supply:
City grid power, self-provided power, diesel oil dynamotor, 3-phase alternating current
380V±15%, 50Hz or 60Hz. The power capacity of the soft start must meet the motor starting requirement.
●
Matched Motor:
Motor should be three phase squirrel asynchronous motor, and its power capacity must be
matched with soft starters.
●
Starting Frequency:
The starting time is according to the loading equipment.
●
Cooling Mode:
Naturally wind cooling.
●
Protective Grade: IP20
●
Environment Conditions:
when altitude is less than 2000m, the temperature of the environment should be
between -10
o
C ~ 40
