1. What Is a Reduced Voltage Soft Starter?
A reduced voltage soft starter is a device that starts motors with lower initial voltage, gradually increasing it to full levels. This avoids the high inrush current of direct-on-line starting. SHUYI’s model protects motors from damage and ensures stable operation in various industrial settings.

2. How It Controls Voltage
SHUYI’s reduced voltage soft starter works through smart voltage regulation:
- Initial Stage: Applies 30–50% of full voltage to start the motor gently.
- Ramp-Up Phase: Increases voltage steadily over 1–30 seconds, based on motor size.
- Full Voltage Switch: Reaches full voltage once the motor reaches stable speed.
3. Key Benefits
- Lower Inrush Current: Cuts startup current to 2–3x rated value, vs. 5–7x with direct starting.
- Extended Motor Life: Reduces mechanical stress by 40%, adding 2–3 years to motor lifespan.
- Energy Savings: Uses 25% less energy during startup, lowering operational costs.
4. Ideal Applications
Perfect for:
- Large Pumps: Prevents pipe damage from sudden pressure surges in water systems.
- Compressors: Ensures smooth startup, reducing wear on pistons and valves.
- Conveyors: Lowers strain on belts and rollers, minimizing downtime from breakdowns.
