In response to the inquiry regarding the operation of the S 3_L Ecoline_24 with a 60 Hz power supply and the potential use of an inverter, our Engineering team has provided the following technical clarification and recommendations.
1. Inverter (Converter) Requirements
When operating the machine via a converter, it is essential to ensure adequate power capacity. As a general guideline, the converter should provide at least double the nominal outlet power of the machine.
The installed motor is rated at 3 kW.
Therefore, a converter with a minimum capacity of 6 kW is recommended.
It is important to note that converter performance varies by manufacturer. Some units may shut down at relatively low amperage levels, while others are capable of tolerating higher amperage loads for several seconds. This variability can significantly influence operational stability and should be carefully considered when selecting the converter.
2. Operation with 60 Hz Power Supply
The machine is technically capable of operating on a 60 Hz frequency. However, certain performance differences must be taken into account:
Motor performance and efficiency are reduced at 60 Hz.
Motor and oil temperatures may increase after prolonged operation.
Maximum torque output is lower, which may prevent the machine from reaching maximum pressure required for full crimping force.
It is important to emphasize that the difference between 50 Hz and 60 Hz configurations affects only the motor. All other components, including the pump and mechanical systems, remain unchanged.
3. Available Options
To ensure optimal performance under a 60 Hz supply, the following options are available:
Operational Testing
The customer may test the machine under 60 Hz conditions to determine whether the performance meets operational requirements.
Motor Replacement
The motor can be replaced with model 264.126, which is specifically designed for 60 Hz operation.
Conclusion
While the S 3_L Ecoline_24 can operate under a 60 Hz power supply, careful consideration must be given to converter sizing and expected performance variations.
For applications requiring full performance and reliability, replacing the motor with a dedicated 60 Hz version is the recommended long-term solution.
We trust this information will assist in making an informed technical decision.
