Function and Working Principle
The ATS480C21Y controls motor starting by reducing initial voltage and gradually ramping it up to full line voltage.
Operating Process
- Reduced voltage is applied to the motor at startup
- Voltage is increased gradually over a programmed ramp time
- Motor torque is controlled to match load demand
- Motor reaches nominal speed smoothly
- Optional soft stop reduces mechanical shock during shutdown
System Flow
Electrical Supply → Soft Starter → Controlled Voltage Output → Motor → Mechanical Load
Key Functions
- Soft start and soft stop control
- Torque control during acceleration
- Reduced mechanical stress on drivetrain components
- Lower starting current compared to direct-on-line (DOL) start
- Built-in motor protection functions
- Suitable for high-inertia loads
Industrial Applications
- Pumps and pumping stations
- Compressors
- Fans and ventilation systems
- Conveyors
- Crushers and mills
- HVAC systems
- Water treatment plants
- Heavy industrial machinery
Installation Notes
- Installed in industrial control panels or MCCs
- Requires proper ventilation due to heat dissipation
- Must be protected by upstream circuit breakers
