Soft Starter Details

  • Simple control panel. The control panel can be removed to clean, easy-to-operate, real-time data display on an LCD screen.
  • Smart mainboard. Soft starter features fast response and multi-functions.
  • Power control transformer. It comes with energy saving, a circulating circuit, and high-quality coils with insulation isolation.
  • Mutual inductor. the mutual inductor makes the soft starter more standard for measuring instruments, protection equipment, and automatic control equipment.

Soft Starter Applications

The soft starter well suits motor, water pump, mixer, air compressor, conveyor, gravel crusher, etc.

Soft Starter Applications

Impact on the grid without soft starter

The impact on the power grid is mainly manifested in two aspects:

1. The impact of the large current directly started by a super-large motor on the grid is almost similar to the impact of a three-phase short circuit on the grid, which often causes power oscillations and destabilizes the grid.

2. The starting current contains a large number of high-order harmonics, which will cause high-frequency resonance with the grid circuit parameters, resulting in faults such as relay protection malfunctions and automatic control failures. The starting current is greatly reduced during a soft start, and the above effects can be eliminated.
