Where: In BMS-controlled electrical panels managing HVAC compressors, chilled water pumps, air-handling units, and escalator motors.

Why: To monitor supply voltage for overvoltage, undervoltage, or phase loss and signal the BMS to trigger alarms or shut down affected equipment before these conditions cause overheating, efficiency loss, or motor damage — ensuring equipment protection, operational safety, and reduced maintenance interventions.

Where: In motor control panels for pumps, compressors, conveyors, and fans, typically installed upstream of the motor starter.

Why: To continuously monitor the supply voltage for conditions like overvoltage, undervoltage, or phase loss, and trip the control circuit before these anomalies damage motor windings, cause overheating, or disrupt operations — ensuring motor protection, process reliability, and reduced unplanned downtime.

Where: In OEM-manufactured electrical panels for machinery like industrial chillers, elevators, packaging machines, and CNC systems, typically installed at the incoming supply point.

Why: To monitor incoming voltage for overvoltage, undervoltage, or phase loss and trigger alarms or system shutdown before abnormal supply conditions damage motors, drives, or sensitive control electronics — ensuring machine reliability, reduced warranty claims, and extended service life of customer equipment.

Where: In commercial submetering panels and retail mall tenant distribution boards supplying power to shops, food courts, escalators, and common-area facilities.

Why: To monitor incoming supply voltage for overvoltage, undervoltage, or phase loss and trigger alarms or disconnect circuits before these conditions damage lighting systems, HVAC units, or tenant equipment — ensuring power quality, equipment longevity, and uninterrupted operation in high-traffic commercial spaces.
