Description

  • Features

  • ● Various starting methods
    Users can select current limit start, voltage ramp start, and can apply programmable kick start and start current limit in each mode. Meet the needs of the site and achieve a good starting effect.
    ● High reliability
    The high-performance microprocessor digitizes the signals in the control system, avoiding the excessive adjustment of the analog circuits in the past, thereby obtaining accuracy and execution speed.
    ● Strong anti-interference
    All external control signals are optically isolated, and different anti-noise levels are set to adapt to use in special industrial environments.
    ● Simple adjustment method
    The control system has a wide range of applications, the mode adjustment is simple and intuitive, and various functional options can be used to match various control objects.
    ● Optimized structure
    The unique compact internal structure design is particularly convenient for users to integrate into the existing system, saving the cost of current transformers and bypass contactors for users.
    ● Power frequency can be set
    The power frequency 50/60Hz is set by parameters, which is convenient for users to use.
    ● Analog output
    4-20mA current output function, user-friendly.
    ● MODBUS-RTU communication
    During 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 default value is 1. The communication baud rate setting range is: 0, 2400; 1, 4800; 2, 9600; 3, 19200; the factory value is 2 (9600).
    ● Perfect protection function
    A variety of motor protection functions (such as overcurrent, input/output phase loss, thyristor short circuit, overheat protection, leakage detection, electronic thermal overload, internal contactor fault, phase current imbalance, etc.) Not damaged during operation.
    ● Easy maintenance
    The monitoring signal coding system composed of 4-digit digital display monitors the working conditions of the system equipment 24 hours a day, and provides fast fault diagnosis at the same time.
