Introduction to SJR3-LN series online soft starter
Product description The L series soft starter is a soft starter developed by our company based on the latest product architecture platform (development code "Leopard") that supports multiple bypass types. Compared with the platform of the previous generation SJR2 series, the "Leopard" architecture has been greatly optimized and improved in software and hardware. Based on the latest 32-bit ARM architecture main control chip, the algorithm performance and functions are further improved. The high-frequency optocoupler-triggered thyristor design replaces the traditional analog pulse drive, which effectively improves the internal conduction efficiency of the thyristor and reduces losses. The built-in power supply design enables the product to adapt to wide voltage fluctuations. The product also has linear temperature detection, adjustable three-phase unbalance tolerance and overload tolerance design, so that it can better adapt to the harsh production environment.
