Product Description: The CMC-HX Soft Starter is a new type of intelligent starting and protection device for asynchronous motors. It is an integrated motor terminal control device that combines starting, display, protection, and data acquisition. Users can achieve complex control functions with fewer components. The bilingual interface (Chinese and English) makes operation more convenient. Additionally, the CMC-HX Soft Starter integrates a current transformer internally, eliminating the need for external configuration.1. SCR TriggeringClosed-loop control algorithm with SCR closed-loop control function, specifically designed for standard and heavy-duty loads. Users can select current-limiting start or voltage ramp start based on the load condition to achieve smooth, torque-oscillation-free starting.2. Load ApplicationTen built-in load types are available for user selection, with starting control curves provided for each type to match the soft starter with the load, ensuring excellent starting and stopping performance.3. Multiple Starting and Stopping MethodsVoltage exponential curve, voltage linear curve, current exponential curve, and current linear curve, with programmable kick-start torque and starting current limits applicable for each method. Depending on the load, the corresponding starting curve can be selected to achieve optimal starting performance. Multiple stopping methods include programmable soft stop, free stop, braking stop, and pump stop. The base algorithm ensures more accurate and smooth motor starting and stopping.4. Communication FunctionStandard Modbus RTU communication. Optional Ethernet/GPRS communication module facilitates network connection and control, enhancing system automation and reliability.5. Analog Signal ControlUsers can input 4–20mA or 0–20mA standard signals and set upper and lower limits for analog values to control motor start/stop and alarms. The soft starter can also transmit data (pressure, temperature, flow, etc.). It features 4–20mA or 0–20mA standard analog signal output functionality.6. Fully Flame-Retardant MaterialUnits below 90KW feature an all-plastic enclosure made of flame-retardant ABS material. For 90KW and above, the upper cover is plastic, and the main frame is made of aluminum-zinc-coated steel plate, offering heat and corrosion resistance.7. External Panel OptionThe panel can be externally extended to the equipment operation surface via the body interface for remote operation, facilitating on-site use.8. Strong Anti-Interference CapabilityAll external control signals are optically isolated, with different noise immunity levels set to suit industrial environments.9. Dual Parameter FunctionFeatures two sets of basic parameters, allowing control of two motors with different power ratings.10. Power FrequencyAdaptive power frequency 50/60Hz function for user convenience.11. Dynamic Fault MemoryCan record up to 10 faults, making it easier to identify the cause of issues.12. Comprehensive Protection FunctionsMonitors current and load parameters throughout operation, with microcomputer-based protection functions including overcurrent, overload, underload, overheating, phase loss, short circuit, three-phase current imbalance, phase sequence detection, and frequency error.13. User-Friendly Human-Machine InterfaceEquipped with an LCD display panel supporting both Chinese and English interfaces, making programming and parameter adjustment more convenient.Control Power SupplyAC110V--AC220V±15% 50/60HzThree-Phase Power SupplyStandard wiring: AC380V, 690V, 1140V±15%; Internal delta wiring: AC380V±15%Rated Current18A--1200A, 23 ratings in totalApplicable MotorsGeneral squirrel-cage asynchronous motorsStarting MethodsVoltage exponential curve, voltage linear curve, current exponential curve, current linear curveStopping MethodsFree stop, soft stop, braking stop, pump stopLogic InputImpedance 1.8KΩ, power supply +24VStarting FrequencySuitable for frequent or infrequent starting; recommended not to exceed 10 starts per hourProtection FunctionsOvercurrent, overload, underload, overheating, phase loss, three-phase current imbalance, phase sequence detection, motor overheating, frequency error, etc.Protection RatingIP00, IP20Cooling MethodNatural cooling or forced air coolingInstallation MethodWall-mountedEnvironmental ConditionsFor altitudes above 2000 meters, derate accordinglyAmbient temperature between -25°C to +45°CRelative humidity not exceeding 95% (20°C±5°C)No flammable, explosive, or corrosive gases; no conductive dust; indoor installation with good ventilation; vibration less than 0.5G
