Product DescriptionProduct Details1. Diversified Start-Stop ModesThe products have four starting modes: voltage ramp start, current ramp start, current-limited start, and heavy load (inrush) start.2. Superior Structural DesignDual CPU structure with mutually redundant reliability design, unique compact internal structure design, facilitating user integration into existing systems. The built-in bypass type lowers the cost of external accessories and reduces the equipment's footprint.3. Rich User InterfacesStandard 485 communication, optional PROFIBUS communication, 1 fault output (passive), 2 programmable relay outputs (passive), 2 programmable logic inputs (active), 1 programmable logic output (active), users can configure according to their needs.4. Comprehensive Protection FunctionsProtection functions include overcurrent, motor overload, three-phase current imbalance, over/under voltage, phase loss, overheating, underload, PTC, and thyristor short circuit.5. Strong ExpandabilityExpandable functions: Internet real-time monitoring module or leakage detection module can be selected for expansion based on needs. (Both are optional accessories but cannot be used simultaneously; only one module can be selected for expansion).6. Complete Display FunctionsThe LCD screen display meets various working conditions, supports language switching between Chinese and English, and supports expandable display screens, facilitating the use of complete cabinets.7. Powerful Memory FunctionDynamic fault memory of over 80 entries, allowing users to easily find the cause of faults at any time, regularly updated, saving storage space.8. Rich System Communication FunctionsBuilt-in communication port, this function allows direct communication with the upper PC to achieve remote control and remote signaling functions. (Standard RS-485 interface, optional PROFIBUS interface).9. Diversified Wiring MethodsApplicable to both internal and external wiring methods for motors.SpecificationATA QB-7 Series Standard Soft StarterSystem VoltageInstallation DimensionsExternal DimensionsMounting HolesAppearancePower(V)H1W1HWDK(kw)(mm)(mm)(mm)(mm)(mm)(mm)A8-5538038120045324219010B75-110380399.5230499270208.510C132-200380429.5260531300208.510D250-320380459.5270559315208.510E40038045044663147028810F500380537644734668355.511G600-800380483893.51045915.550011B132-200690399.5230499270208.510C250-400690429.5260531300208.510D500-600690459.5270559315208.510Technical SpecificationsMain CircuitPower DeviceThyristor Module/Standard ThyristorMain Circuit Power SupplyThree-phase 380V +10%-15%, 50/60HzMain Circuit Power Consumption<2W per phase per amperePower Device Voltage≥1400Vdv/dt ProtectionRC Filter Circuit, VaristorControl CircuitControl Circuit VoltageAC 220V (+10%, -15%), 50/60HzControl Circuit Power Consumption5WStart CommandPassive Contacts, Keyboard, Computer CommandsStarting ParametersStarting MethodCurrent Ramp, Current Limiting Start, Voltage RampStarting Voltage30%~90% (System Voltage)Starting Time5~120sJump Time0~3sStopFree StopSoft Stop0~30sFault ProtectionPower Supply Fault ProtectionPhase Loss, Undervoltage, OvervoltageEquipment Fault ProtectionOverheating, Motor Overload, Motor Phase Loss, Start Timeout, PTC Protection, Underload, Three-phase Imbalance, Thyristor Short Circuit, Overcurrent, Ground Leakage Protection, etc.Online MonitoringDisplayStarting, Running Status and Starting, Running Current and Voltage, Active Power (optional) and Power Factor (optional)Auxiliary OutputRelay Output 1Normally Open Relay Contact, AC250V/2ARelay Output 2Normally Open Relay Contact, AC250V/2AFault Relay OutputRelay Contact, AC250V/2ALogic Output 1Open Collector Output (+12V, +24V), 50mALogic Output 2Open Collector Output (+12V, +24V), 50mAAnalog Output4~20mA or 0~20mA Standard SignalDigital CommunicationCommunication InterfaceStandard 485, PROFIBUS OptionalEnvironmental ConditionsOperating Temperature-5~+40℃Storage Temperature-25~+55℃Relative Humidity20~90%, Non-condensingAltitude<2000m, Rated Value Unchanged>2000m, Rated Value -5%/100mProduct Technical StandardsGB 14048.6-2016Drawing & DimentionsCompany ProfileAOKO Global LimitedAOKO, a professional manufacturer of soft starters and variable frequency drives since 1998, holds ISO and CE certification with over 80 patents demonstrating industry innovation.
