Description
Sourced and supplied by Al Imran Enterprises, Lahore, Pakistan. The Omron LG2-AB is a compact, economical plug-in voltage sensing relay from the LG2 series, designed to detect AC voltage and switch its DPDT output contacts when the monitored voltage crosses the set point. Available in 100 VAC, 110 VAC and 200 VAC rated models, the LG2-AB is widely used for undervoltage and overvoltage protection of motors, power converters, and industrial control circuits. Each LG2-AB unit is factory-rated for a specific AC voltage (100 VAC, 110 VAC, or 200 VAC) — buyers should specify the required rated voltage when ordering.
