Product Overview
LDR Series yog lub cim tshiab ntawm cov khoom siv tiv thaiv relay tsim rau cov chaw tsim hluav taws xob, cov chaw sib txuas, cov chaw faib khoom thiab cov tshuab hloov hluav taws xob. Nws muab kev tiv thaiv zoo rau cov khoom siv tseem ceeb xws li cov kab nyiaj siv ua haujlwm, cable feeders, transformers, motors thiab capacitor banks ntawm voltage theem ntawm 35kV thiab hauv qab no.
Cov cuab yeej siv lub tshuab microcomputer sib xyaw ua ke, siab -precision tam sim no thiab voltage transformers, siab - rwb thaiv tsev intermediate relays thiab txhim khu kev qha switching fais fab mov modules. Nws cov qauv compact, ua tiav kev tiv thaiv kev teeb tsa, muaj zog tiv thaiv - muaj peev xwm cuam tshuam thiab siv hluav taws xob tsawg ua rau nws tsim nyog rau kev teeb tsa ncaj qha thiab kev faib tawm hauv cov txee hloov.
