The main role of the built-in bypass motor soft starter

1.The main role of the built-in bypass motor soft starter

The motor soft starter is a new motor starting and protection device which combines power electronic technology, microprocessor and automatic control. It can start/stop the motor smoothly without step, avoid the mechanical and electrical impact caused by the traditional starting mode of starting the motor such as direct starting, star/triangle starting, autovacuum starting, etc., and can effectively reduce the starting current and distribution capacity, to avoid increased capacity investment. At the same time, LCR-E series soft starters are integrated with current transformers and contactors, so users do not need to connect them externally.

2.The features of the built-in bypass motor soft starter:

1, a variety of starting modes: the user can choose current limiting start, voltage ramp start, and can apply programmable jump start and starting current limit in each mode. To meet the needs of the field to achieve the best starting effect.

2. High reliability: The high-performance microprocessor digitizes the signal in the control system, avoiding excessive adjustment of the previous analog line, so as to obtain excellent accuracy and execution speed.

3, strong anti-interference: all external control signals are photoelectric isolation, and set up different noise resistance levels, suitable for use in special industrial environments.

4, simple adjustment method: The control system has a wide range of applications, the way of adjustment is simple and intuitive, and it can match all kinds of different control objects through various functional options.

5, optimized structure: unique compact internal structure design, especially convenient for users to integrate into the existing system, for users to save the cost of current transformer and bypass contactor.

6, power frequency adaptive: power frequency 50/60Hz adaptive function, easy to use.

7, analog output: 4-20mA current output function, easy to use.

8, communication: In the network communication, 32 devices can be connected. Users can achieve the purpose of automatic communication by setting the baud rate and communication address. The communication address setting range is 1-32, and the factory value is 1. Communication baud rate setting range: 0, 2400; 1, 4800; 2, 9600; 3. 19200; The factory value is 2(9600).

9, perfect protection function: a variety of motor protection functions (such as over current, input and output phase deficiency, thyristor short circuit, overheating protection, leakage detection, electronic thermal overload, internal contactor failure, phase current imbalance, etc.) to ensure that the motor and soft starter in the fault or misoperation is not damaged.

10. Easy maintenance: The monitoring signal coding system composed of 4-digit digital display can monitor the working condition of the system equipment 24 hours a day and provide rapid fault diagnosis.
