Year1
The series soft starter is a newly developed Chinese intelligent AC motor soft starter with internationally leading technology developed by Tongqi Electric Technology Co., Ltd.
The series of intelligent AC motor soft starters are designed and produced using power electronics technology, microprocessor technology and modern control theory. They are new motor starting equipment with today's internationally advanced level. This product can effectively limit the starting current of asynchronous motor starting, and can be widely used in fans, water pumps, conveying and compressor loads, traditional star/delta conversion, self-coupling step-down, magnetic control step-down and other voltage-reducing starting equipment. The ideal replacement product.
The series of soft starters not only have the same excellent performance as international high-end soft starters, but also combine with China's application characteristics to further strengthen product reliability, environmental adaptability, and humanized and industrialized design. Can meet the needs of various applications.
Comply with standards
Features and functions
Features
◆
Series soft starters adopt high-performance microprocessor technology, with higher performance and wider voltage adaptability range specialty.
◆
A variety of starting modes can be selected, which can maximize the best effect of the motor and achieve soft parking.
◆
Large-screen LCD human-machine interface, Chinese (Han display) display mode, easy to operate, the LCD display can reflect the different states of the soft starter, fully embodying the humanized design concept.
◆
Multiple protection monitoring functions, thermal overload protection and protection based on the temperature of the load, and fault records can be queried to provide a basis for fault analysis.
◆
This product can provide ~analog output, communication interface (using and communication protocol), which can enter parameter setting, operation and monitoring through the host computer to achieve high intelligent control.
◆
Actual power setting When the power of the soft starter is greater than the actual load power, the rated current of the soft starter can be set according to the actual load so that the power of the soft starter matches the load to ensure starting, operation, protection, etc. Accuracy of parameters.
◆
Programmable output relay can easily realize interlock control with other equipment.
Function
◆
Reduce the starting current of the motor and reduce Distribution capacity avoids investment in capacity expansion
◆
Reduces starting stress and extends the service life of motors and related equipment
◆
Smooth starting and soft stopping avoid the breathing of traditional starting equipment Vibration problems and water hammer effect
◆
Multiple starting modes and wide range of current and voltage settings can adapt to various load situations and improve the process
◆
Perfect and reliable Protection function, more effectively protect the safety of motors and related equipment
Can be used in situations with frequent starts and stops.
Perfect motor protection function
◆
External fault input protection (instantaneous Stop terminal) is used to add special protection devices, such as thermal relays and motor protectors
◆
Loss of voltage protection After the soft starter is powered off and powered on again, no matter what state the control terminal is in, it will not Will start on its own to avoid injury accidents
◆
Long starting time protection If the soft starter fails to start within the set time due to improper parameter settings or other reasons, the soft starter will protect itself
◆
Soft starter overheat protection: The protection operates when the temperature rises to ℃, and the action time is < when the temperature drops to ℃ (the minimum overheat protection is released
◆
Input phase loss protection lag time< Seconds
◆
Output phase loss protection lag time
Three-phase unbalance protection lag time
Start The overload protection time is the protection time when the current continues to be greater than the rated operating current of the motor at startup
◆
The operating overload protection time is based on the rated operating current of the motor for inverse time thermal protection. Refer to the tripping protection shown in the figure. Time curve
◆
Power supply voltage over-voltage protection delay time When the power supply voltage is higher than the limit value, the protection action time
Low power supply voltage protection delay time: When the power supply voltage is lower than the limit value, the protection action time <; otherwise, when it is higher than the set value, the protection action time
Load short circuit protection delay time<, The current is more than times the nominal motor current rating of the soft starter.
