Smooth Transitions, Maximum Protection

Our Soft Starter Panels provide an advanced solution for managing the high inrush currents and mechanical shocks associated with starting large induction motors. Unlike traditional Direct-On-Line (DOL) starters, our soft starter systems use solid-state technology to gradually increase the voltage, ensuring a “soft” and controlled acceleration that protects your electrical grid and extends the life of your mechanical equipment.

• General Description: A specialized control panel equipped with a microprocessor-controlled soft starter unit. It is designed to eliminate “water hammer” in pumping systems and reduce belt slippage or gear damage in industrial machinery. These panels are the ideal middle ground between a standard Star-Delta starter and a full Variable Frequency Drive (VFD).

• Key Technical Specs:

  • Voltage Range: Custom-built for 380V – 415V and higher industrial voltage requirements.

  • Capacity: Designed to handle motors from 7.5 kW up to 500 kW and beyond.

  • Ramp Control: Fully adjustable “Start Ramp” (acceleration) and “Stop Ramp” (deceleration) times to suit specific load types.

  • Enclosure Rating: Available in IP54/IP55 for indoor factory use or IP65 with integrated cooling for outdoor installations.

• Protection & Efficiency:

  • Advanced Motor Protection: Integrated electronic overload protection, phase-loss detection, and under-voltage/over-voltage monitoring.

  • Bypass Contactor: Many of our panels include an integrated or external bypass contactor that engages once the motor reaches full speed, reducing heat generation and saving energy.

  • Reduced Peak Demand: Significant reduction in starting current (typically 2.5x to 3x of rated current), preventing voltage dips that can affect other equipment on your site.

• Applications:

  • Pumping Stations: Prevents pressure surges and “water hammer” in pipes.

  • Compressors: Ensures a smooth start-up against high pressure.

  • Conveyor Belts: Prevents sudden jerks that can damage products or snap belts.

  • Large Fans & Blowers: Reduces mechanical stress on large-diameter impellers and bearings.

Why Choose Square EIC Soft Starter Panels?

1. Mechanical Longevity: By eliminating the sudden torque “kick” of a standard starter, our panels can double the life of your couplings, bearings, and belts.

2. User-Friendly Interface: Equipped with digital displays for real-time monitoring of motor current, thermal load, and fault history.

3. Space-Efficient Design: Our panels offer a more compact footprint than traditional Star-Delta configurations, saving valuable space in your electrical room.
