ОПИСАНИЕ ПРОДУКТА
ASEA BROWN BOVERI PSR72-600-70 - Softstarter
The ABB PSR72-600-70 is a compact, three-phase softstarter engineered for controlled acceleration and deceleration of AC induction motors. It utilizes thyristor-based voltage control to mitigate current peaks and mechanical stress during motor startup and shutdown, extending equipment lifespan. This unit is suitable for applications such as pumps, fans, compressors, and conveyors requiring smooth motor operation and reduced inrush current.
