1. Riferimento alla selezione

The PSR series soft starters cover a rated current range of 3~45A, with optional control voltages of 24VDC or 100~240VAC, suitable for applications with moderate starting performance requirements and limited space. For more advanced functions (per esempio., controllo della coppia, communication functions), ABB PSS (Universal Range) or PST (Intelligent Range) series soft starters are recommended.
