DC Leakage Current Monitor (MDLA-100)

DC Leakage Current Monitor

 

 

 

 

FEATURES

General
This DC Leakage Current Monitor constantly observes leakage current of DC circuit like as PV generation system, etc. and lights up the warning lamp with signal output, when the leakage current exceeds the setting value.
