MEsoftstart

Developed and manufactured by Ario for Mitsubishi Electric Europe

Industry-hardened low voltage soft starters

Intelligent motor start-up – reducing stress on your assets & electrical distribution …

 

 

Why Use a Soft Starter?

  • Intelligent motor start-up – reducing stress on your assets & electrical distribution, avoiding excessive starting current and torque
  • Built-in motor protection
  • Controlled acceleration
  • Controlled de-acceleration
  • Improved efficiency
  • Extending the life of motors and connected equipment

Highlights of the MEsoftstart/I soft starter range

  • Range of only 5 models covering 11kW to 1400kW motors
  • Both soft start and soft stop supported
  • Easy to set up | monitor:
    • "pro" variants: colour touch screen and PC app | Modbus TCP & RTU
    • "core" variants: potentiometers and PC app | Modbus RTU
  • Available for 400V, 525V and 690Vac electrical supplies
  • Designed for operations in the harshest conditions:
    • Up to 60°C ambient, with zero derating up to 50°C
    • Up to 3000m above sea level, with no derating up to 1400m
  • Fit and forget – robust power electronics for extremely long life
  • 2 versions available: with / without internal bypass contactor

User Interface (Potentiometer or touch screen display; PC application for configuration, monitoring and control)

Potentiometers – very simple, often preferred.
Used on low cost soft starters

Keyboard and display – more complicated, but flexible.
Used on high-end soft starters

 

 

Rich set of control and monitoring functions
    • Full suite of starting profiles on the Pro models:
      • Multiple Voltage ramps:
        time-linear, RMS-linear and S-Curve
      • Kick start
      • Pedestal
      • Current limit start
      • Constant current ramp up
    • Application pre-sets:
      3 pump curves, generator and torque control
    • Restart delay: settable starts per hour
    • Built-in digital motor protection and self-diagnostics
    • All 3 phases monitored and controlled - no neutral conductor (N) required
    • Controller is line powered - no auxiliary supply needed
    • Terminals for 6-wire | inside-delta motor winding – economical substitute for star-delta starters
    • Remote start/stop control (via IO or communication link)
    • Bypass contactor control outputs
    • Soft starter state and fault outputs
