Peter electronic has expanded its industrial motor-control portfolio with the VersiStart II plus, a next-generation soft-starter series now covering a complete performance range from 6 A to 105 A. Engineered for durability, high switching frequency, and advanced motor protection, the series is designed for global OEMs, automation integrators, and operators of demanding industrial systems. With models supporting motors from 3 to 55 kW, the VersiStart II plus provides a robust and future-proof solution for modern installations.
The VersiStart II plus employs two-phase controlled soft starting, in which two supply phases are directly controlled by power semiconductors while the third phase remains unregulated. This architecture reduces harmonic distortion, improves torque stability, and provides a smoother, more reliable motor startup.
A microcontroller-based ramp system manages acceleration and deceleration, enabling predictable and repeatable startup behavior. Key technical advantages include:
These characteristics make the VersiStart II plus ideal for applications with frequent start–stop cycles, high mechanical load requirements, or sensitive electrical networks.
The mid- and high-current versions (38–105 A) incorporate comprehensive diagnostic and protection features that go beyond standard soft-start functionality:
Lower-current models (6–32 A) also offer complete soft-start functionality, including:
Peter electronic recommends selecting the soft starter one performance class higher when operating high-efficiency IE3 motors due to their inherently higher starting currents.
The VersiStart II plus series is housed in a robust IP20 industrial enclosure and optimized for fast, flexible panel integration:
All models incorporate:
These mechanical and electrical design features ensure fast installation, reduced wiring complexity, and long-term reliability.
These data summaries offer a quick comparison across all current ratings, ensuring accurate dimensioning, seamless integration into control systems, and reliable long-term operation.
