DOL STARTER PANEL – STAR-DELTA STARTER PANEL
Linear Power Control offers a comprehensive selection of motor starter panels, including both Direct On-Line (DOL) and Star-Delta configurations. Understanding the distinct functionalities of each system empowers you to choose the optimal solution for your specific application.
DOL Starter Panels: Simplicity and Efficiency
- Direct Connection: DOL panels provide the most straightforward starting method, connecting the motor directly to the power supply for a full-voltage, high-torque start-up.
- Cost-Effectiveness: DOL panels are the most economical option, making them ideal for applications with smaller motors, such as submersible pumps, deep well pumps, or booster sets.
- Key Features:
- Full voltage and constant frequency operation
- High starting torque
- Rapid acceleration times
Star-Delta Starter Panels: Reduced Current, Lower Stress
- Controlled Start-Up: Star-Delta panels utilize a timed system to switch control contractors, enabling a two-stage starting process. This reduces the initial current surge and associated mechanical stress on the motor.
- Lower Starting Current: Compared to DOL, Star-Delta starting significantly minimizes starting current and torque, typically around 33% of the direct on-line values.
- Applications: Star-Delta panels are particularly beneficial for larger motors or applications where minimizing inrush current is crucial.
