Its compact design is ideal for space-constrained motor control centers, simplifying installation. This built-in bypass soft starter, with advanced control and protection features and closed-loop control for stabilized soft start torque, provides a user-friendly, efficient, and reliable motor start and run solution. Equipped with three internal relays, it eliminates the need for external contactors. Please specify your requirement for this built-in contactor model when ordering, as the standard version is an economic typeOperation InterfaceUser-Friendly Interface: Enjoy a simple and clear operation interface with an LCD display, making it easy to monitor motor status and adjust settings.Enhanced Display & Stable Power: The wide-screen display is complemented by a switching power supply, ensuring the cooling fan maintains a constant speed for optimal performance.Robust Protection: Benefit from built-in thyristor short-circuit protection and adjustable start overcurrent time for enhanced safety and motor longevity.Automated Operation: Features like automatic start-up on power restoration and a timed boot function provide greater convenience and control.Sales Highlight PointOptimized StructureUser-Friendly InterfaceImpeccable Motor ProtectionOur product features a unique modular design with a convenient top-entry, bottom-exit connection mode. We've incorporated advanced anti-jamming techniques and a rational control panel layout, alongside an I2C bus keyboard for a compact footprint. This optimized structure significantly streamlines integration and system assembly.Our system offers a rich and intuitive keyboard display, making operation straightforward. You can easily set and modify start, stop, operation, and protection parameters to suit various loads, with real-time display of all working states. The interface also allows for convenient inquiry of per-phase operating current, machine temperature, and power frequency.Our system offers online operation with real-time monitoring of working voltage, current, and temperature, providing comprehensive motor protection. You can control the moderate protection threshold to ensure your motor operates with maximum stability.Optimized Starting for Diverse Loads High Technical PerformanceHigh ReliabilityOur system offers a wide range of starting modes and convenient parameter settings, allowing you to easily achieve the best possible starting performance for your motor, regardless of the load type.Our system delivers consistent and accurate operating performance without the need for circuit parameter adjustments. This is all thanks to its high-performance microprocessor and powerful software support functions, which fully simplify and optimize the control circuit.We ensure high reliability in our products by rigorously screening all electrical components. The entire control system undergoes high-temperature cyclic and vibration testing, guaranteeing dependable performance.Resettable Rated Output CurrentExcellent Soft Stop PerformanceIndustrial Fieldbus SupportOur soft starter allows you to adjust its actual output current within a certain range. This means that even if the soft starter's nominal power exceeds your actual load, you can reset it to match the real load. This ensures both accurate starting performance and precise motor protection.Our system delivers smooth stopping regardless of whether it's during startup or normal operation, once the work mode is set. With reasonable parameter settings, you can achieve a gentle stop tailored to various loads, proving especially beneficial for applications like filling lines and water pumps in production.Our system includes 485 communication functionality and supports the Modbus communication protocol, an international standard.Technical SpecficationSwitchModeThyristorVoltage of Power SupplyAC380V±15% (220V/380V/440V/660V customizable)Start FrequencyFrequent orinfrequent start available, It is advised not to exceed 20 times each hour.ApplicableMotorSquirrel-cage three-phase asynchronous motorRelay OutputTwo wayprogrammable ouotput relayDisplayLarge screen LCD, Chinese and English display mode.
