CMC-LX 3 phase Soft Starter, AC380V, 7.5 ~ 630kW

Low Voltage Soft Starter

CMC-LX 3 phase Soft Starter, AC380V, 7.5 ~ 630kW

CMC-LX series motor soft starter is a new type of motor starting and protection device that combines power electronics technology, microprocessor and automatic control.

It can start/stop the motor smoothly without steps, avoiding mechanical and electrical shocks caused by traditional starting methods such as direct starting, star-delta starting, and auto-buckling starting. And can effectively reduce the starting current and distribution capacity to avoid capacity expansion investment.

CMC-LX series soft starter integrates a current transformer inside, and users do not need to connect it externally.

Mains voltage: AC 380V±15%

Applicable motor: Squirrel cage AC asynchronous(induction) motor

Power range: 7.5~630 kW

    • Features

    • ● Unique SCR triggering close-loop control algorithm
      The unique SCR close-loop control is specially designed for standard load and heavy load. User can choose current-limit start or voltage ramp start according to load conditions so as to realize absolutely smooth start without torque oscillation.

      ● High control precision
      Adoption of high-performance Cortex-M3 32-bit inner core CPU for central control with features of fast speed, high precision and  strong capability of anti-interference.

      ● Simple and compact appearance
      Three-in and six-out structure of main circuit under patent protection and built-in current transformer with easy wiring and high reliability.

      ● Standard MODBUS-RTU protocol
      When ordering, users can choose whether to carry the standard MODBUS-RTU communication protocol according to the actual situation.

      ● Integrated with advanced protective function
      Protective functions of phase failure, overload, overcurrent, phase current unbalance, thyristor overheat to protect motor and other equipment.

      ● Fireproof material
      The product of below 90kW is in plastic structure made with inflaming retarding ABS material; for the product of 90kW and above, the upper cover is in plastic structure and main frame is made of aluminium-zinc plate with features of heatproof and corrosion resistance.

      ● Movable panel
      The panel can be moved to equipment operating surface through machine interface for remote control.

      ● Easy maintenance
      The monitor signal coding system consists of 4-digit display monitors working state of the equipment for 24 hours and provides fast fault diagnosis.
