Product Overview
LR800‑90‑280KW split‑type online intelligent soft starter cabinet is a high‑power intelligent motor control product integrating advanced motor control, protection and processing technologies. No external contactor is needed, replacing conventional star‑delta and auto‑coupling step‑down starting devices. Built upon ordinary soft starter upgrades, it ensures outstanding performance and high operational stability for medium‑large motors.
It suppresses motor starting impulse current, lowers power system capacity demand and saves grid upgrading costs. It reduces mechanical impact stress on motors and driven loads to prolong equipment service cycle. Soft shutdown function avoids water hammer and inertial‑related failure risks. Three configurable starting modes adapt to heavy‑duty and complicated load conditions. Full‑range protection safeguards motor and production safety. Intelligent networking function realizes remote monitoring, matching the development trend of power system automation.
