Key Features and Operating Benefits
Adjustable Starting and Stopping
Starting voltage, ramp time, and initial torque can be adjusted to suit compatible motor and load requirements. Controlled acceleration and stopping help reduce mechanical shock during operation.
Multiple Starting Modes
The cabinet provides six starting modes and two stopping modes, allowing configuration for different starting and stopping requirements. The appropriate mode depends on the driven equipment and operating conditions.
Motor and System Protection
Protection functions cover short-circuit, starting, operating, stall, and fast protection. The applicable protection settings should be configured for the motor and system.
LCD Monitoring and Fault Information
The LCD displays voltage, current, and other operating parameters, helping operators monitor running conditions and identify faults during troubleshooting.
Industrial Applications
Water Supply and Wastewater Pumps
Suitable for compatible water supply, circulation, and wastewater pumping systems. Motor power, pump load, starting frequency, and the required control sequence are key matching factors.
Industrial Fans and Blowers
Used for ventilation, exhaust, and process-air systems where controlled motor starting helps reduce starting impact on the drive system. Check fan inertia, motor ratings, and the required starting performance.
Belt Conveyors
Applicable to compatible conveyor drives in material-handling systems. Conveyor loading, belt tension, starting torque, and loaded-start requirements should be considered when matching the starter.
Chemical and Process Equipment
Can be integrated into compatible pumps and other motor-driven process equipment. Selection should account for the motor rating, process load, control requirements, and the electrical installation environment.



OEM Supply and Replacement Matching
OEM Integration
PUTAI supports OEM integration and project supply for compatible low-voltage motor starting systems. The starter configuration can be coordinated with the motor, driven equipment, control system, and cabinet installation requirements.
Replacement Compatibility
For replacement projects, buyers should provide the motor nameplate, rated voltage and current, motor power, load type, starting frequency, control requirements, cabinet dimensions, and relevant wiring diagrams. These details help assess electrical compatibility, installation fit, and control-system interfaces.
The cabinet may replace a star-delta or autotransformer starter only after the motor, load, operating sequence, and system requirements have been checked. A soft starter is not a direct substitute for every existing starting method.
Project Documentation and Delivery
Available project documentation may include technical specifications, wiring diagrams, installation information, and operating instructions, according to the confirmed supply scope. Packaging and delivery arrangements can also be coordinated with project requirements.
Manufacturing Capability
PUTAI operates a 200,000 m² manufacturing facility, with RMB 80 million in fixed assets and more than 120 employees, including 18 technical engineers. These company-level figures indicate manufacturing scale; product-specific capability should be assessed alongside the actual cabinet configuration and supporting records.
Quality Assurance
Quality assurance should be demonstrated through product-specific inspection and test records. Relevant evidence includes assembly inspection, wiring checks, functional verification, protection-function checks, and final inspection documentation where applicable. Buyers can request available records for the actual model and project.
