Solid State Reduced Voltage Starters (Soft-Start) SSW-07: 6hp - 400hp

          
Description:
Soft-Starters are static starters that accelerate, decelerate and protect three-phase induction motors. The control of the voltage applied to the motor by means of adjustments to the firing angle of thyristors allows the soft-starter to start and stop an electric motor smoothly.
 
The SSW-07, with DSP (Digital Signal Processor) control was designed for high performance on motor starts and stops with an excellent cost-benefit ratio. Easy to set up, it simplifies start-up activities and daily operation.
 
The SSW-07 is compact optimizing space in electric panels. It already incorporates electric motor protection. It adapts to customer needs through its easy-to-install optional accessories.
 
The SSW-07 adapts to customer needs through its easy-to-install optional accessories. Thus, a keypad, a communication interface or a motor PTC input can be added to the product.

 

Applications:

Features:
  • Reduction of mechanical stresses over the coupling and transmission devices (gearboxes, pulleys, gears, conveyors) during the start
  • Increases motor and machine mechanical equipment lifetime due to the reduction of mechanical stress
  • Easy operation, setup and maintenance
  • Simple electrical installation
  • Operates in environments up to 55C (without current reduction for all models)
  • Integral, electronic motor protection
  • Kick-Start function for starting high breakaway torque loads
  • Reduces Water Hammer in pump applications
  • Limitation of voltage drop during start
  • Universal voltage (208 to 575 VAC)
  • Switched mode power supply with EMC filter for the control electronics (110 to 240 Vac)
  • Built-in by-pass providing size reduction and energy saving
  • Voltage monitoring of the electronics allows to back-up I x t values (thermal image).
