- Dual-Phase Startup Mechanism
SHUYI star delta starter operates in two phases. Initially, it uses star connection to reduce voltage by 30%, then switches to delta mode for full power. This avoids sudden current surges common in direct starts. - Cost-Effective Design
Compared to complex variable speed drives, this starter offers affordability. It uses fewer components while maintaining efficiency, making it a budget-friendly choice for small to medium industrial motors (7.5-75kW). - Reduced Mechanical Stress
By lowering initial voltage, the star delta starter cuts mechanical strain on motor windings and connected equipment. Pumps, compressors, and conveyors experience less wear, extending service life by 20-30%. - Easy Integration & Operation
SHUYI’s design simplifies installation. It fits standard control panels and requires minimal wiring. The user-friendly interface allows quick setup of transition time (typically 5-10 seconds) between star and delta modes. - Built-In Protection Features
The starter includes overload and phase-failure protection. It shuts down automatically if current exceeds safe limits or phases are unbalanced, preventing motor damage and ensuring workplace safety. - Suitable for Specific Industrial Needs
It excels with constant-speed applications. Ideal for centrifugal pumps, fans, and mixers—equipment that doesn’t require variable speed but needs gentle startup to avoid system shocks.
