Description

Three Phase AC380V/660V/1140V 7.5KW Smart Squirrel-Cage Asynchronous Electric Motor Thyristor Soft Starter
 
Three Phase AC380V/660V/1140V 7.5KW Smart Squirrel-Cage Asynchronous Electric Motor Thyristor Soft Starter is a new type start-up equipment which integrates electronic techniques, computer techniques and modern control theory. It is the new generation product to replace the conventional star-delta starter, self-coupling voltage-drop starter and magnetic control voltage-drop starter.
1. Voltage control type and current limiting type
2. Digital and single chip control
3. Human-machine interface available
4. Space saving thanks to natural cooling with small housing design
5. Protection function: over voltage, over current, over load, over heat, short circuit, lower voltage, input or output phase failure, three phase imbalance, starting time over long protection etc.
6. Customization is available for specified application and requirement

Maintenance
1. Dust: If too much dust, it will reduce the insulation level of the soft starter, even causes the soft starter does not work.
Brush the dust with clean and dry brush.
Remove dust with compressed air machine.
2. Condensation: If condensation, it will reduce the insulation level of soft starter, even causes the soft starter does not work.
(1) Blow it with a hair dryer or electric stove.
(2) Bring it to power distribution room for dehumidification.
3. Regularly check components' intact. Whether it can work properly.
4. Check soft starter' cooling channel, ensure they are not clogged by dirt and dust.
Before maintenance checking, it has to cut off all power in the line side of soft starter.
