💡 What is a three-phase voltage monitor used for in industrial control panels? A three-phase voltage monitor watches line voltages and trips relays or alarms when voltages fall outside safe limits, helping prevent equipment damage and downtime. Here's a quick intro and how it helps: - Detects over/under-voltage conditions and phase-loss to protect motors and drives - Provides relay outputs for alarm signaling, control interlocks and automation integration - Handy for panel-mount installations in motor control centers, switchgear and power distribution
