Product Overview
LR800‑320‑600KW split‑layout online intelligent soft starter cabinet is designed for high‑power heavy‑load motor working scenarios. Combining modern motor control theory, multi‑dimensional motor protection and mature processing craft, this product cancels external contactor configuration, and is an ideal upgrade alternative for star‑delta and auto‑transformer step‑down starting equipment. Optimized on the base of general soft starters, it realizes enhanced performance and high reliability for large‑capacity motor drive occasions.
It greatly restricts motor starting inrush current, decreases power distribution capacity requirement and prevents investment for power grid expansion. It relieves mechanical starting stress of large‑power motors and connected loads, extending the service life of motors and mechanical equipment. The soft‑stop function effectively handles inertial loads. Three dedicated starting modes cope with harsh and complex heavy‑load startup conditions. Complete protection system prevents equipment damage from various electrical faults. Intelligent networking interface supports data communication, satisfying higher requirements of modern electric automation system for large motor control.
