Three-in-one Inverter for Stretch Wrapper

This Three-in-One Inverter for Stretch Wrapper is developed by Wuxi Ruisida Electric. We have operated our factory for 10 years and are ISO 9001 certified. We also operate our own PCBA production line, ensuring stable quality control from design to manufacturing.

This inverter is specifically designed for stretch wrapping systems that require multiple motor drives. Traditional systems typically use three separate inverters, which occupy significant space inside the electrical cabinet and require complex wiring and commissioning. This increases installation time and the risk of wiring errors.

This integrated solution combines three inverter functions into a single unit. It significantly reduces cabinet space and simplifies wiring. The inverter also receives signals from the tension sensor and supports closed-loop tension control, ensuring consistent film tension throughout the entire wrapping cycle.

The inverter communicates with the main controller via an RS485 communication interface, providing stable and reliable data transmission.
The power ratings are 0.75 kW, 0.75 kW, and 0.4 kW, matching the three drive motors in a standard turntable stretch wrapper:
1.Turntable motor
2.Carriage up/down motor
3.Pre-stretch roller motor
Speed control is based on intelligent closed-loop tension control logic. The system continuously reads real-time sensor data and automatically adjusts motor speed to maintain the preset tension value.
In 2021, we shipped 80,000 fast door control systems and 5,000 wrapper control systems. Our current monthly production capacity reaches 20,000 units. We maintain safety stock of key components to ensure stable delivery performance.
In 2022, we acquired our own factory building, further improving production capacity and quality control capability.

This inverter is suitable for turntable stretch wrappers, strapping machines, and other packaging equipment requiring multi-motor coordination.
We provide a 3-year warranty for the complete unit and long-term technical support. For international customers, we offer remote debugging and online troubleshooting services.
Samples are available for evaluation before bulk orders. Customization is also supported, including special voltage, power configurations, and application-specific adjustments.
This Three-in-One Inverter for Stretch Wrapper simplifies cabinet design, reduces wiring complexity, and improves system reliability. It ensures stable tension control and consistent wrapping quality in industrial applications.
