Compressor Electric Motor Soft Starter High Start Torque Low Current
NK series built-in bypass soft starter is a full digital product. Suitable for squirrel-cage asynchronous motors. Rated voltage from 200V--525V, Rated power from 0.75--37kW. The soft starter can control the motor to accelerate smoothly in the process of stopping, It also provides a comprehensive protection function for motors and itself.
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

Ambient Temperature -25+45°C
Ambient Humidity 95%(20°C±5°C)
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.
