Solutions that Match Requirements
ISA TS - IGBT Based Starter
Advanced IGBT-Based Soft Starter for Medium Voltage Motors
The ISA TS is a pioneering medium voltage soft starter that utilizes advanced IGBT technology. It is specifically designed for applications that require high starting torque while minimizing the impact on the electrical grid. As a result, operators can start large motors reliably, even in weak power networks.
Unlike conventional starting methods, the ISA TS delivers exceptionally low starting currents while maintaining high motor torque. Consequently, it reduces grid disturbances and minimizes voltage drops during motor starting.
Reduce Starting Current While Maintaining High Torque
The innovative design of the ISA TS enables motors to start with grid currents that are often lower than the motor’s rated operating current. Therefore, users can safely start demanding applications without placing excessive stress on the power supply system.
In addition, the ISA TS reduces grid loading and helps improve overall system stability. This makes it an ideal solution for critical applications where power quality and network reliability are essential.
Proven Medium Voltage Motor Starting Technology
For decades, industries around the world have relied on our expertise in developing and manufacturing advanced motor starting solutions. As a result, customers benefit from reliable performance, improved operational efficiency, and reduced installation costs.
Furthermore, the ISA TS expands the application range of medium voltage soft starters. It offers a practical and cost-effective alternative to variable frequency drives in applications that do not require speed control.
A Cost-Effective Alternative to Variable Frequency Drives
By combining low starting current, high starting torque, and advanced motor protection, the ISA TS provides a unique solution for challenging motor starting applications. Moreover, its compact design can reduce space requirements while lowering overall project costs.
Consequently, operators gain a reliable medium voltage motor starting solution that improves efficiency, reduces grid impact, and delivers long-term value.
