Product Overview
The LR800‑18.5‑75KW split‑layout online intelligent soft starter cabinet adopts cutting‑edge motor control theory, motor protection and processing technologies. It eliminates the requirement for an external contactor and serves as an ideal substitute for star‑delta and auto‑transformer step‑down motor starting equipment. Optimized from general soft starters, it delivers superior performance with stable and reliable operation.
It effectively lowers motor starting current to reduce power distribution capacity and avoid grid expansion investment. It mitigates starting stress for motors and loads to extend equipment service life. Equipped with soft‑stop function, it solves problems of inertial systems that traditional starting devices cannot handle. Three optional starting modes support diverse complex motor‑load working conditions. Comprehensive protection mechanisms secure motors and production assets, while built‑in intelligent networking capability meets modern power automation requirements.
