Typical Applications Pumps, fans, compressors, conveyors, industrial motor control
The ABB PSE25‑600‑70 is a compact industrial soft starter designed to ensure smooth starting and stopping of three‑phase AC motors by controlling the applied voltage during acceleration and deceleration. It helps reduce inrush current, minimize mechanical stress, and improve the lifespan of motors and driven equipment compared with direct‑on‑line (DOL) starts. The unit is suitable for light‑to‑medium duty applications such as pumps, fans, compressors, conveyors, and HVAC systems in industrial and commercial environments.
