2、 Technical Highlights: Precise Control and Intelligent Protection

Adaptive current limitation

The ATS48C25Q can adjust the starting current in real-time according to the load, avoiding motor overheating or grid impact. For example, when starting the water pump, the current limit can be accurately controlled within 300% of the rated value, significantly extending the service life of the equipment.

Built in bypass contactor

After startup, it automatically switches to bypass mode to reduce energy consumption (power consumption<5W) and improve operational efficiency.

Motor thermal protection

By monitoring the temperature and current of the motor, dynamically adjusting the protection threshold to prevent motor burnout caused by overload.

Fault diagnosis and recording

Supports recording of 10 types of faults (such as overcurrent, phase loss, overheating), which can be quickly resolved through LED display screens or communication interfaces.

3、 Application scenario: Full coverage from industrial to civilian use Pump and fan system

In water supply and HVAC scenarios, the soft parking function of ATS48C25Q can eliminate water hammer effects, reduce pipeline vibration, and extend equipment life.

Compressor and conveyor belt

For heavy-duty start-up requirements, the current limiting start-up mode can smoothly increase torque and avoid mechanical impact.

Food processing and packaging machinery

Compact design and IP54 protection level, suitable for humid and dusty environments, ensuring production continuity.

4、 Selection suggestion: How to match the requirements?

power matching

Choose a soft starter based on the rated power of the motor. The 25A model is suitable for motors ranging from 7.5kW (380V) to 15kW (690V), with a 20% margin reserved to cope with peak loads.

Environmental adaptability

If installed outdoors or in high dust areas, it is recommended to choose an IP54 protective casing and add a cooling fan.
