Product Description
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.
