Model Definition

 

AC6KV Solid State Soft Starter High Voltage With Perfect Motor Protection

Features

  1. Free of maintenance:Thyristor is an electric device without contacts. Different from other kinds of products that need frequent maintenance on liquid and parts etc., it turns the mechanical lift into the service life of electronic components, so it needs no maintenance after running for many years.
  2. Easy installation and operation:NKS300 is a complete system for controlling and protecting the starting of motor. It can put into operation only with the power line and motor line connected. The whole system can be tested electrically under low voltage before operating with high voltage.
  3. Backup:The starter comes equipped with a vacuum contactor which can be used to start the motor directly in the inside. If NKS300 fails, the vacuum contactor can be used to start the motor directly to ensure the continuity of the production.
  4. High voltage thyristor is a component of major loop, equipped with voltage balancing protection system and over-voltage protection system.
  5. NKS300 comes equipped with an electromagnetic blocking device for fear of entering the high voltage device in the electrified state.
  6. Advanced optical fiber transmission technique realizes the triggering detection of high voltage thyristor and the isolation between LV control loops.
  7. 32-bit ARM-core microcontroller is used to perform central control which is real-time and high efficient with , high reliability and excellent stability.
  8. LCD/touch screen display system in both Chinese and English with human-friendly operation interface.
  9. RS-485 communication port can be used to communicate with the upper computer or centralized control center.
  10. Aging experiments are made on all circuit boards.
