High Voltage Solid-State Soft Starter 3 kV 6 kV 10 kV

Product description

The RWSQ1 Series High Voltage Solid-State Soft Starter offers multiple advantages, including compact size, low power consumption, high reliability, high sensitivity, contactless operation, maintenance-free performance, zero environmental pollution, and convenient installation.

Compared with traditional starting methods, the RWSQ1 features an intelligent control system that allows easy and precise setting of start torque, start current, start time, and stop time. It can also be networked with computers, PLCs, and other control systems for advanced automation.

The device has been widely applied in various industries such as machinery manufacturing, cement production, metallurgy, mining, oil extraction, chemical processing, water treatment, and petrochemicals. It is suitable for loads including:

• Pumps

• Fans

• Pumping units

• Air compressors

• Ball mills

• Cranes

• Compressors

• Crushers

• Conveyors

• Elevators

• Centrifuges

• Rolling mills

Key Features

• Modular design: Each module uses high-power thyristors with optically isolated triggering, ensuring reliability and consistency.
• Comprehensive protection: Built-in over-voltage, under-voltage, over-current, overload, and phase-loss protections with automatic fault alarms and trip shutdown.
• Advanced cooling system: Includes RC snubber circuits and vacuum contactors for enhanced safety and extended equipment life.
• Optical fiber triggering: Strong anti-interference design guarantees stable and reliable triggering.
• Integrated control platform: Equipped with a 32-bit ARM microcontroller for precise control, with a Chinese/English LCD interface for easy operation.
• Smart control: Parameters such as starting torque, starting current, starting/stopping time are easily configurable. Supports networking with PLCs and computer control systems.
• Wide applicability: Suitable for pumps, fans, compressors, conveyors, crushers, mills, and other heavy-duty industrial loads.
