Bypass Soft Starter: Energy-Efficient Motor Control Solution With Built-in Contactor For Smooth Start/Stop

Bypass Soft Starter: Energy-Efficient Motor Control Solution with Built-in Contactor for Smooth Start/Stop

The Bypass Soft Starter is an all-in-one motor control device that combines soft starting, soft stopping, and multi-protection functions. By integrating a bypass contactor, it eliminates the need for external contactors, reducing installation complexity and costs. Ideal for applications requiring frequent motor starts/stops, such as conveyors, pumps, and compressors.

Key Features

① Multiple Starting Modes

• Current Limit Soft Start: Limits inrush current to prevent grid disturbances.
• Voltage Ramp Soft Start: Gradually increases voltage for smooth acceleration.
• Ramp + Current Limit Start: Combines both modes for heavy-load applications.

② High Reliability

• Microprocessor Control: Digital signal processing ensures strong anti-interference capabilities.
• Opto-Isolation Design: Protects control units from harsh industrial environments.

③ Comprehensive Protection

• Overcurrent, phase loss, SCR short circuit, and overheating protection safeguard motor longevity.
  (Includes overcurrent, phase failure, SCR short-circuit, and overheating protections to ensure motor safety.)

④ Energy Efficiency

• Under light-load conditions, the soft starter reduces motor voltage to minimize reactive current, improving the power factor by up to 20%.
  (During light-load operation, it automatically lowers voltage to reduce reactive power, boosting the power factor by up to 20%.)

Applications

"Widely used in industries requiring precise motor control and energy savings, including:"
(Applicable across sectors demanding precise motor management and cost-effective operation, such as:)

• Mining & Quarrying: Soft starts for conveyors and crushers reduce mechanical stress.
• Water Treatment: Eliminates water hammer effects in pumps, extending pipeline life.
• HVAC Systems: Smooth compressor starts prevent grid voltage fluctuations.
• Manufacturing: Enhances reliability for frequent motor cycling on production lines.
