Detailed Description

Product Overview:

The CMC-MX built-in bypass motor soft starter is an intelligent asynchronous motor soft starter based on a trigger closed-loop algorithm for voltage regulation and current limiting. Power electronic circuit detection and advanced closed-loop control algorithms enable starting and protection functions. The built-in bypass contactor contacts use magnetic latching contactors, which differ from other externally bypassed AC contactors that operate under long-term electrification. This product is noise-free, free from electromagnetic pollution, spark-free, and environmentally friendly.

Model Description:

Technical Features:

1. Multiple Starting Methods

Users can choose between current-limiting start, voltage ramp start, and apply programmable kick start and starting current limits in each mode. This meets on-site requirements and achieves excellent starting performance.

2. Reliability

The microprocessor digitally processes signals in the control system, avoiding excessive adjustments typical of analog circuits, thereby ensuring high accuracy and execution speed.

3. Strong Anti-Interference

All external control signals are optically isolated, with different noise immunity levels set to suit industrial environments.

4. Easy Adjustment

The control system has a wide range of applications, with simple and intuitive adjustment methods. Various functional options allow it to match different control objects.

5. Optimized Structure

The compact internal design makes it particularly convenient for users to integrate into existing systems, saving costs on current transformers and bypass contactors.

6. Power Frequency Adaptability

Adaptive power frequency of 50/60Hz for user convenience.

7. Analog Output

4-20mA current output function for user convenience.

8. MODBUS-RTU Communication

Supports connection of up to 32 devices in network communication. Users can set baud rates and communication addresses for automatic communication. The communication address range is 1-32, with a default value of 1. The baud rate options are: 0 for 2400; 1 for 4800; 2 for 9600; 3 for 19200; the default value is 2 (9600).

9. Comprehensive Protection Functions

Multiple motor protection features (such as overcurrent, input/output phase loss, thyristor short circuit, overheating protection, leakage detection, electronic thermal overload, internal contactor failure, phase current imbalance, etc.) ensure the motor and soft starter are protected from damage during faults or misoperations.

10. Easy Maintenance

A monitoring signal coding system with a 4-digit display provides 24-hour monitoring of the system's operational status and enables quick fault diagnosis.
