Electronic Soft Starters
Electronic soft starters are designed for large asynchronous motors to reduce voltage during startup via phase control. This prevents current peaks and mechanical stress. Since torque decreases quadratically with lower voltage, soft starts are ideal for low-load applications. Many of our models feature an integrated bypass relay to reduce power loss once full voltage is reached. Soft starters are modern, efficient replacements for traditional
star-delta switches.
Starting methods for electric motors
Soft Start or Frequency Inverter?
While soft starters reduce voltage,
frequency inverters (VFD)
control the frequency. A VFD provides high torque even at low speeds, making it perfect for heavy starts (e.g., compressors starting against pressure) or applications requiring precise speed control and controlled deceleration.
SSCi Series Soft Starters
The economical SSCi series is designed in accordance with IEC/UL/KC standards. These starters feature:
- Integrated Bypass: Reduces heat and increases energy efficiency.
- DIN Rail Mounting: Simple installation for industrial cabinets.
- Built-in Thermal Protection: The SSCi monitors motor current and calculates temperature in real-time, tripping at 105% to prevent burnout without needing external relays.
- LED Diagnostics: Two front-mounted LEDs for instant fault identification.
